USING COREL TEXTURE™ 1Corel TEXTURE� lets you create patterns from rock, marble, clouds, or

other materials. A texture is the surface revealed by slicing a

three-dimensional object. For example, when you slice a block of wood at

different angles, you create surface features that show growth rings, a

straight grain, or a veneer effect. You can control the appearance of the

pattern to reflect the cutting knife, the direction of the cut, and how the

edges of the cut are beveled. You can also control the color and lighting

effects that enhance the appearance of a texture.

You create textures by combining four properties:

� Lighting � manipulates one, two, or three spotlights that shine onto a

texture�s surface

� Shader layers � contain a material, a color, and a blend

� Topography� defines the surface contour of a texture. The shape of the

surface, such as waves, ripples, and bumps, is controlled by the shape of

the knife that slices the material.

� Edge � creates a round, beveled, or flat border for a texture

You can design and edit textures at any time. You can make natural textures,

such as wood, stone, ripples, clouds, and bumpy surfaces. You can also create

patterns of checkers, dots, and lines or combine natural textures with these

patterns. The textures you create have consistent characteristics over their

entire surface and may be produced at resolutions suitable for either

electronic or paper formats.

Creating a surface by slicing an object

A texture is a surface created by slicing a solid object. Resolution, object

dimensions, and pattern irregularity are important concepts to understand

when slicing a surface.

Object dimensions

You can slice a material in any direction and from any angle. A texture is the

surface revealed by slicing the object. Depending on the type of material, you

can produce a wide range of surface features. For example, when cut at

different angles, a marbled surface can have veins or spots.

You must define the size and characteristics of your texture: narrow and thin,

or wide and short. You can view the image from up close or far away to gain

different perspectives. When you render a texture � or transform it into a

bitmap image � the size and resolution you choose determines how much of

the surface detail is shown.

Details in rendered resolutions

The resolution of a rendered texture affects surface detail. Fine details

appear as you move closer to the object. This means that larger images are

not blow-ups of smaller images. The resolution detail remains the same and

the quality does not degrade as the image is enlarged.

Pattern irregularity

The internal structure of the materials used to create textures often has a

regular pattern. This pattern, in wood or granite for example, appears when

the material is sliced. You control the regularity of a pattern by creating a

uniform texture or allowing the pattern to degrade randomly. You can also set

up a pattern in which half the elements are uniform and half are random.

Unrendered texture designs

Unrendered texture designs include all the properties of a texture, as well as

a thumbnail image used to draw the texture.

The textures you create, along with preset patterns, are in a texture file

format. These textures simulate surfaces, such as stone, clouds, and waves.

Corel TEXTURE files share a few characteristics:

� Texture designs can be edited and modified at any time.

� Texture designs have a relatively small file size (40-50Kb.)

� Texture designs must be rendered before being used in other applications.

Rendered texture designs

A rendered texture is converted to a bitmap that may be imported into other

applications. You can render a texture to your screen, where the image may

be reviewed for any final changes. Remember the following points about

rendered textures:

� You can use rendered textures in other applications.

� You can specify the size and resolution of a rendered texture. Resolution

depends on the intended use of the texture. Electronic documents require

a low resolution, while printed documents require a high resolution.

2 Corel TEXTURE�: Chapter 1

� Rendered textures are saved as .BMP files.

� You cannot edit or alter a rendered texture in Corel TEXTURE. However,

you can import the rendered image into another program and edit it as a

bitmap.

Getting started with Corel TEXTURE™You create unique textures for use as backgrounds for a Web site, wall paper

on your desktop, or part of a design you are making in another application.

You can create a new texture by designing one from a blank texture, from a

preset texture, or using Texture wizard.

Creating a texture from a blank texture

Starting with a blank texture lets you create a custom design. You begin with

a �blank slate� in which two lights shine on a flat, black, featureless surface.

Creating a new texture is the best way to experiment with designs.

To create a texture from a blank texture

1 Click File, New.

2 Enable the Blank Texture button.

3 Click the New button.

Creating a texture by modifying a preset texture

Corel TEXTURE provides preset textures that you can modify to create new

images. Use the Texture gallery to browse through the available textures.

To create a texture by modifying a preset texture

1 Click File, New.

2 Enable the Texture Preset button.


4 Click a tab to view the contents of the page.

5 Choose a shade from the Texture Type list box.

6 Double-click the image in the gallery.

� To avoid overwriting the preset texture, save the texture with a new

filename.


Creating a texture using the Texture wizard

The Texture wizard helps you create complex, custom textures from scratch.

The Texture wizard guides you through all the steps required to create a

texture by prompting you for design decisions. At any time, you can back up

and specify different settings.

To create a texture using the Texture wizard

1 Click File, New.

2 Enable the Texture wizard button.


4 Follow the on-screen instructions.

Specifying texture size and resolution

The texture size you specify depends on how you plan to use the texture.

You may use it as a Web page background, as part of a composite image, or as

part of another application. The texture resolution you define depends on

whether the texture is produced as an electronic file or printed on paper.

To specify texture size

1 Click File, Image Setup.

2 Enable one of the Measurement Units buttons.

3 Type a value in the Texture Width box.

4 Type a value in the Texture Height box.

To specify texture resolution

1 Click File, Image Setup.

2 Enable one of the Resolution Units buttons.

3 Type a value in the Texture Width box.

4 Type a value in the Texture Height box.


� The settings you specify affect the rendering time and the size of the

rendered texture file. A large, high-resolution texture file takes longer to

render.

� Different printing and display formats require different resolution values.

Textures intended only for screen display should be set at 72 dots per inch

(dpi.) Most printed textures are set at 150 dpi, regardless of the printer

resolution. Geometric patterns with sharp line boundaries require a

higher resolution.

Defining lighting propertiesLighting properties determine the amount, intensity, and quality of the

illumination on a texture�s surface. You can create lighting effects by

manipulating up to three spotlights hanging above the surface of the texture.

You can turn on some, none, or all of the lights and change their positioning.

You can assign a different color to each light. Lighting is also affected by the

surface properties of the texture.

You can adjust the following properties for each light:

� Ambient � sets the overall intensity of the light shining on a texture�s

surface. Increasing the ambient light brightens the surface of the texture.

� Shading � sets the amount by which color values are reduced to create

shading

� Highlights � sets the amount of contrast created by each light

Setting lighting properties

You can view a three-dimensional representation of both the texture and the

lights that shine on a surface. Up to three lights may be turned on and

positioned above the texture. You can also change the color of the lights.

Turning lights on and off

Lighting properties control how the light shines on the surface of the texture.

You can specify the number of lights that you want to use. Lighting controls

have no effect on the texture when all three spotlights are turned off.

To turn a light on

1 Click the Lighting Properties layer.

2 Enable the Light check boxes to turn each light on.


To turn a light off


2 Disable the Light check boxes to turn each light off.

Positioning a light on a texture surface

The position of each light is represented three-dimensionally and may be

moved around the texture. The texture is divided into four quadrants; the

arrow in the middle indicates the top of the texture.

To position lights on a texture surface

1 Enable one or all of the Light check boxes.

2 Drag a light pin to a position on the texture.

Adjusting the ambient light

You adjust the ambient light to alter the intensity of the lighting on the

texture. Higher ambient light values brighten the surface; lower values

darken the surface.

To adjust the ambient light


2 Move the Ambient slider to adjust the amount of ambient light applied to

the texture.

Adjusting the shading

Shading controls the amount of shadowing that is created by surface

irregularities. As you increase shading, shadows lengthen and surface

elements stand out more clearly. A low shading level creates a dark image

with less visible features. A high shading level creates a lighter image with

more visible features.

To adjust the shading


2 Move the Shading slider to adjust the amount of shading applied to the

texture.


Adjusting the Highlights

Highlight values determine the amount of light reflected from the highest

points on a surface. The tops of bumps, ripples, and waves stand out more

clearly as you increase the amount of surface highlighting.

To adjust the highlights


2 Move the Highlights slider to adjust the amount of highlighting applied to

the texture.

Applying a preset lighting effect

You apply a preset lighting effect to give a texture a predefined look. You may

want to use a preset effect if you are creating multiple textures with similar

or identical lighting patterns.

To apply a preset lighting effect

1 Click the down arrow button on the Lighting title bar.

2 Choose the lighting effect you want to use from the Lighting flyout.

Applying color to lights

Each of the three light sources can have its own color. When you shine a

colored light on the surface of a texture, the color of the light blends with the

colors defined for each shader layer. You can change, create, and edit the

color of lights.

Applying color to a light

You add color to lights by dragging colors from the color swatches bar onto

the light pins. The color of the pin changes, as does the color of the light

reflected on the texture in the three-dimensional representation.

To add color to a light

� Drag a color from the Color Swatches Bar onto a light pin.

Changing the color of a light

You can create new colors and edit the brightness and opacity of existing

colors by using the Color Wheel.


To change the color of a light

1 Double-click a color on the Color Swatches Bar.

2 Drag the color shade indicator in the Color Wheel.

3 Move the Brightness slider to adjust the brightness of the color.

4 Move the Opacity slider to adjust the transparency of the color.

5 Drag the new color from the Color Swatches Bar onto a light pin.

Understanding surface propertiesSurface properties are the defining characteristics of a texture. Surface

properties act like a filter, controlling how the lighting properties interact

with the shader layers.

Setting Surface properties

You set the surface properties of the texture by adjusting the roughness,

brilliance, metallicity, and graininess properties until you have the texture

you want. These effects create a realistic surface for the texture.

To set surface properties

� Move any of the following sliders:

� Roughness� adjusts the overhead lighting applied to the texture; a

low roughness setting focuses each spotlight into a small, intense

circle. As you increase the roughness setting, the light gradually

spreads over the surface of the texture.

� Brilliance� adjusts the length and depth of shadowing applied to the

texture; surface irregularities, such as bumps and wrinkles, stand out

more clearly as you decrease the brilliance setting

� Metallicity � adjusts the metallicity applied to the texture; at low

metallicity, a large amount of surface lighting appears in the final,

composite texture. At high metallicity, the color is almost entirely

taken from the shader layers.

� Graininess� adjusts the graininess applied to the texture; as you

increase the graininess setting, the texture becomes more obscure

Understanding shader layersYou can use shader layers to apply color, surface features, or pictures to a

layer in a texture. Each texture is composed of one or more shader layers.


Since a texture is created by looking down through each layer, you should

define the bottom layer first and then work your way up.

Defining shader layers

Shader layers are opaque, transparent, or semitransparent layers that alter

the color, texture, and blend of the texture. You define the blend and surface

features, as well as the color, for each layer in the texture.

Defining shader layers

Each shader layer contains adjustable parameters, such as opacity, pattern,

and color that contribute to the overall appearance of the texture.

To define shader layers

1 Select the bottom shader layer.

2 Choose an algorithm from the Algorithm list box.

3 Move any of the following sliders:

� Magnification slider � adjusts the surface detail applied to the texture

� Rotation slider � rotates the texture

� Turbulence slider � adjusts the texture�s smoothness

� Variance slider � sets the uniformity of the turbulence setting

4 Click the Preview Selected Layer button to preview the changes made to

the bottom layer.

� The blend setting for the bottom layer is always opaque.

� You can use the preview command to preview the effect of combining all

the shader layers.

Manipulating shader layers

You can delete, reorder, copy, or save shader layers for use in other textures.

Disabling a shader layer lets you see how the texture looks with a layer

removed.

Deleting a shader layer

You delete shader layers from the stack if you no longer want them in the

texture. Once the layer is deleted, the texture loses all the properties defined

in that layer.


To delete a shader layer

1 Click the shader layer you want to delete.

2 Click Texture, Remove Layer.

� You can also use the Delete Layer button on the property bar to delete the

layer.

Changing the order of a shader layer

Shader layers are represented in the three-dimensional model as layers in a

stack. You change the appearance of the texture by changing the order of the

layers.

To change the order of a shader layer

1 Click the shader layer you want to move.

2 Drag the layer to a new position.

Copying and pasting a shader layer into another texture

You can move shader layers from one texture to another. Once you insert the

layer into the stack, the texture reflects the properties of the new layer.

To copy a shader layer

1 Click the shader layer you want to copy.

2 Click Edit, Copy Layer.

To paste a shader layer

1 Click File, Open.

2 Open the texture into which you want to paste the shader layer.

3 Select the layer onto which you want to paste the new properties.

4 Click Edit, Paste.

Saving a shader layer in a texture

Shader layers in textures can be saved and used in different textures. If you

are creating multiple textures with similar characteristics, you may want to

save particular shader layers.


To save a shader layer in a texture

1 Click a shader layer.

2 Click the Down Arrow button on the Shader Layer title bar.

3 Choose Save Layer from the Shader Layer list box.

4 Type a name for the layer in the Save Layer dialog box.

Enabling and disabling a shader layer

Shader layers can be temporarily excluded from the stack. If you are

experimenting with the look of a texture, you may want to disable a

particular shader layer.

To enable a shader layer

� Enable the Shader Layer check box in the upper left corner of the Shader

Layer title bar.

To disable a shader layer

1 Click a shader layer.

2 Disable the Shader Layer check box in the upper left corner of the Shader

Layer title bar.

Applying color to layers

You can add, remove, save, and load preset color patterns. All available colors

are located on the color swatches bar. You move colors from the color

swatches bar to the color gradient bar to apply a color or several shades of

color to any shader layer in a texture. The color gradient bar lets you use

color pins to define exactly how colors will blend. The placement of a color

pin indicates the highest point of intensity for that color. On either side of the

color pin, the color gradually fades and blends into the color defined by the

next closest pin.

Colors marked with an �X� are transparent colors � solid colors with

transparent bands that allow colors and other elements from lower layers to

show through.

Adding a color pin to the color gradient bar

Color pins are used to transfer colors from the color swatches bar to the

color gradient bar. You can view the changes to the layer as you drag color

pins to the Color Gradient bar.


To add a color pin to the color gradient bar

1 Drag a color from the Color Swatches Bar to the Color Gradient Bar.

2 Drag the color pin to the location you want.

Removing a color pin from the color gradient bar

You remove a color from the color gradient bar by removing color pins. You

can view the changes to the shader layer as you drag color pins from the

color gradient bar.

To remove a color pin from the color gradient bar

1 Click the color pin you want to remove.

2 Drag the pin off the Color Gradient Bar and out of the work Area.

Changing the color of a color pin

You can add colors to the color gradient bar by changing the color of the color

pins. This lets you alter the colors of the texture but maintain the original

color pattern.

To change the color of a color pin

1 Click a color pin on the Color Gradient Bar.

2 Drag the new color from the Color Swatches Bar to the color pin.

Saving a color set contained in the color gradient bar

You can save the color set used in your texture for future use. If you are

creating multiple textures with the same color pattern, you may want to save

a color set.

To save a color set

1 Click the Down Arrow button beside the Color Swatches Bar.

2 Choose Save Color Set from the Color Swatches Bar flyout.

3 Type a name for the color set in the Save Color Set dialog box.

Loading a preset color set into the color gradient bar

You can load preset color patterns. If you are creating multiple textures with

the same color pattern, you may want to load a preset color set.


To load a preset color set

1 Click the down arrow button beside the Color Swatches Bar.

2 Choose the color set you want to import from the Color Swatches Bar

flyout.

Applying blend settings

Blend settings define how a layer combines with the layers underneath it to

create a composite texture. You can use 11 blend settings to create distinct

effects. For example, by combining opaque shader layers with layers of

varying transparency, you control how dark or how light the features of the

texture appear.

Applying a transparent color to a shader layer

Using transparent colors is similar to placing a colored filter over a camera

lens � light shines through, but it is subtly altered or colored. By combining

different opacity settings with transparent colors, you can control how each

layer contributes to the final texture. Transparent colors are marked with an

�X� on the color swatches bar. A layer that contains a solid color and has a

fully opaque setting blocks all light coming from below. The bottom shader

layer is automatically assigned an opaque blend setting.

To apply a transparent color to a shader layer

1 Select a shader layer.

2 Drag a transparent color swatch from the Color Swatches Bar to the Color

Gradient Bar.

3 Adjust the position of the color pin until you are satisfied with the color

effect.

Applying the additive blend setting to a shader layer

In an additive blend setting, the color values of the additive layer are added to

the color values of the lower layers. An additive blend lightens the texture.

White in the additive layer blocks out any color from the lower layers. Black

in the additive layer has no effect on color from the lower layers.

To apply the additive blend setting to a shader layer


2 Choose Additive from the Blend list box.


Applying the subtractive blend setting to a shader layer

In a subtractive blend setting, the color values of the subtractive layer are

subtracted from the color values of the lower layers. A subtractive blend

darkens the texture.

White areas are converted to black in a subtractive blend. Black areas do not

change the underlying colors.

To apply the subtractive blend setting


2 Choose Subtractive from the Blend list box.

Applying the lighten blend setting to a shader layer

The lighten blend setting brightens all the colors in a texture.

To apply the lighten blend setting


2 Choose Lighten from the Blend list box.

Applying the darken blend setting to a shader layer

The darken blend setting darkens all the colors in a texture.

To apply the darken blend setting to a shader layer


2 Choose Darken from the Blend list box.

Applying the shade blend setting to a shader layer

The shade blend setting turns a solid colored layer into a layer in which

colors gradually shift from light to dark.

To apply the shade blend setting to a shader layer


2 Choose Shade from the Blend list box.

Applying the hue shift blend setting to a shader layer

The hue shift blend setting inverts all the color pins in the layers below the

hue-shifted layer. For example, a red color pin becomes a green color pin.


To apply the hue shift blend setting


2 Choose Hue Shift from the Blend list box.

Applying the multiply blend setting to a shader layer

The multiply blend setting acts like a color filter, allowing some color to show

through and blocking other colors. In a layer to which the multiply blend is

applied, white lets all colors show through, a color with a medium brightness

lets some color show through, and black does not let color show through.

To apply the multiply blend setting


2 Choose Multiply from the Blend list box.

Shader layer algorithm settings

An algorithm is the type of graphic effect contained in the shader layer. For

example, the clouds algorithm creates the effect of a cloudy sky. You control

the look of each texture by changing, for example, the magnification,

contrast, or orientation of an algorithm. The following sixteen algorithms can

be applied to a shader layer:

� colored � applies a solid color to a shader layer

� clouds � creates the effect of a cloudy sky

� marble � creates marble patterns, such as streaks and spots

� wood � creates wood grain, veneer or growth rings

� checkers � creates a checker pattern

� spots � creates a spotted pattern

� agate � creates a blue or gray quartz pattern

� granite � creates a uniform, sandpaper pattern

� polka dots � creates a polka dot pattern

� wrapped� creates a spiral pattern of circles

� fractal � creates a design of circular streaks

� weave � creates a pattern of interlocking bands

� wisps � creates a pattern similar to clouds

� noise � creates a pattern similar to television static


� cellular � creates a honeycomb network of bumps

� picture � lets you import a picture from another application

Applying a preset algorithm to a shader layer

You can apply preset algorithms or graphic effects to any shader layer. If you

are creating multiple textures with the same pattern, you may want to apply

a preset algorithm.

To apply a preset algorithm to a shader layer

1 Select the shader layer you want to change.

2 Choose an algorithm from the Algorithm list box.

Applying the colored algorithm to a shader layer

The colored algorithm applies a solid color to a shader layer. You can use the

colored algorithm to add a tint to a texture or to create different shades by

combining different colored layers. The amount of color added by each layer

to the overall texture is controlled by the blend setting. For example, blend

settings can be transparent, semi-transparent, or opaque.

When you apply the colored algorithm to a shader layer, you must choose a

gradient for the color. Gradients are used to create surface designs by

applying the color as either a solid color or a wash that flows from light to

dark.

To apply the colored algorithm to a shader layer


2 Choose Colored from the Algorithm list box.

3 Choose a gradient option from the Gradient list box.

4 Choose a blend option from the Blend list box.

Applying the clouds algorithm to a shader layer

The clouds algorithm creates the effect of a cloudy sky. This algorithm is

derived from the spots algorithm, with added settings for turbulence. If you

want a cloud pattern without turbulence, try modifying the spots algorithm

until you get the results you want.

To apply the clouds algorithm to a shader layer



2 Choose Clouds from the Algorithm list box.


� Magnification slider � adjusts the magnification level applied to the

layer; a low level of magnification creates many small clouds. A high

level of magnification creates a few large clouds.

� Rotation slider � adjusts the rotation angle of the layer. Rotation

changes the orientation of the clouds.

� Turbulence slider � adjusts the amount of turbulence applied to the

layer; a low level of turbulence creates smooth, rounded edges for each

cloud. A high level of turbulence gives each cloud a jagged appearance.

� Variance slider � adjusts the variance setting; with low variance most

elements in the pattern have the same turbulence setting. With high

variance, turbulence settings are applied randomly.


� You can type values for the three-dimensional transformation parameters

in the Layer Orientation dialog box if you want to adjust the cut of the

layer.

Applying the marble algorithm to a shader layer

You create marble patterns by slicing a simulated block of marble in different

directions. The direction of the cut determines whether the surface contains

streaks, bands, or spots.

Applying the checkers algorithm to a shader layer

The checkers algorithm applies a pattern created by slicing a cube made of

small, rectangular blocks. With magnification set to 1.00, the texture has

eight blocks on each side. Checkers are ideal for making tablecloth patterns.

To apply the checkers algorithm to a shader layer


2 Choose Checkers from the Algorithm list box.



layer; a low level of magnification creates many small blocks. A high

� Contrast slider � adjusts the contrast level of the layer; the contrast

setting determines the shades of colors that are taken from the color

gradient bar


layer; as turbulence increases, the edges of each block become more

ragged until a �salt and pepper� pattern is produced







layer.

Applying the spots algorithm to a shader layer

The effect of the spots algorithm is created by looking down on a surface

rather than slicing an object. The model for the spots algorithm is an


irregular mountain range. Peaks and valleys are assigned colors from

opposite ends of the color range shown in the color gradient bar.

Intermediate elevations are assigned colors from the middle of the color

gradient bar.

Applying the weave algorithm to a shader layer

The weave algorithm creates a pattern of individual shapes that interlock in a

uniform pattern.

To apply the weave algorithm to a shader layer


2 Choose Weave from the Algorithm list box.


� Magnification slide � adjusts the magnification level applied to the

layer; a low level of magnification creates many small, clearly defined

weaves. A high level of magnification creates a few large weaves.

� Rotation slider � adjusts the rotation of the weave pattern. Rotation

determines the direction of the weaves. For example, horizontal,

vertical, or diagonal.

� Bias slider � adjusts the bias of the pattern; a low bias setting uses the

colors found on the left side of the color gradient bar. A high bias

setting uses the colors found on the right side of the color gradient bar.

� Gain slider � adjusts the amount of space between the individual

weave patterns

Importing a picture into a shader layer

You can import a picture from another application into the bottom shader

layer. You can achieve dramatic effects by filtering the picture through other

shader layers. When you import a picture into a shader layer, Corel

TEXTURE attaches the picture file to the texture file. This attachment

ensures that the texture design always contains the most up-to-date version

of the picture file.

To import a picture into a shader layer


2 Choose Picture from the Algorithm list box.

3 Click the Import button on the work area.

4 Choose the drive where the picture file is stored from the Look In list box.

5 Double-click the folder in which the picture file you want to import is

stored.

6 Double-click the filename.

7 Do any of the following:

� Click the Stretch button to stretch the picture to fit over the entire

texture surface.

� Click the Center button to center the picture in the middle of the

shader layer.

� Click the Tile button to create a tiled pattern from the imported

picture.


Defining form and geometryYou can use form and geometry settings to apply a contour, topography, or an

edge to the surface of a texture. These properties give the texture a

three-dimensional appearance.

Topographic algorithms create contours on the surface of your texture. You

can create bumps, dents, ripples, waves, or a flat surface. You can adjust the

magnification, height, and frequency parameters of topographic algorithms.

The edge property of a texture specifies the type and size of the texture�s

border. You can specify a bevel, round, extruded, or picture frame border.

Form and geometry algorithm settings

The form and geometry algorithm settings apply topographic effects to a

texture�s surface. You can control the look of each texture by changing, for

example, the magnification, turbulence, or frequency of an algorithm. The

following eight algorithms can be applied to the form and geometry layer:

� wave � creates concentric waves

� ripple � creates small waves

� wrinkles � creates the effect of a crumpled piece of paper

� bumps � creates a pattern of raised bumps

� dents � creates indentations or pits on a surface

� bump maps � creates a bumpy surface on imported .BMP and .TIF files

� cellular � creates a honeycomb network of bumbs or cells

� weave � creates a pattern of interlocking shapes

Applying the wave algorithm

The wave algorithm creates concentric waves radiating from the center of

the texture.

To apply the wave algorithm

level of magnification creates a few large waves.


� Height slider � adjusts the height of topographic elements; increasing

the height setting creates a more dramatic effect

� Frequency slider � adjusts the number of visible topographic

elements; a low level of frequency creates a few large waves. A high

level of frequency creates many small waves.

Applying the bumps algorithm

The bumps algorithm creates raised bumps on a texture�s surface. The

frequency and distribution of the bumps are random.

To apply the bumps algorithm


2 Choose Bumps from the Algorithm list box.







� You cannot adjust the three-dimensional cut of the bumps algorithm.

Applying the dents algorithm

The dents algorithm creates indentations or pits in a texture�s surface. The

frequency and distribution of the dents are random.


To apply the dents algorithm


2 Choose Dents from the Algorithm list box.




dents. A high level of magnification creates a few large dents.

� Height slider � adjusts the height of topographic elements;

increasing the height setting creates a more dramatic effect



layer.

Applying the bump map algorithm

The bump map algorithm carves text or pictures into wood, stone, and other

textures. The contrasting colors in the picture determine the relative height

of the bumps. Corel TEXTURE uses the following scale to determine how

elements are placed in relation to the surface of the texture:

� Black elements are placed below the texture�s surface.

� Elements that are 50 percent gray are placed level with the texture�s

surface.

� White elements are placed above the texture�s surface.

Black and white pictures create high-contrast images. Grayscale pictures

create softer images. Corel TEXTURE translates color images into grayscale

images before creating the bump map.

To apply the bump map algorithm


2 Choose Bump Map from the Algorithm list box.

3 Click the Import button on the work area.

4 Double-click the folder containing the picture you want to import.

5 Double-click the filename, and click OK.

Creating three-dimensional effects with edges

Edge properties define the border around a texture. The textures you create

begin as flat surfaces. You can simulate depth by setting the size and shape of

the border that surrounds a texture.

Defining edge properties

Edge properties define the border of a texture. There are many edges to

choose from, including bevel, round, and picture frame.

To define edge properties



2 Choose a border effect from the Edge list box.

3 Move the Bevel slider to change the size of the border; moving the slider

to the left decreases the thickness of the border. Moving the slider to the

right increases the thickness of the border.

Rendering texturesRendering transforms a texture into a bitmap image that you can use in other

applications. You can render a texture to a window or a file. When you render

an image to a window, you can view the final image immediately. Rendering

to a window is faster than rendering to a file, and you can make sure that the

rendered texture matches your design. This feature is useful with large,

complex textures that require a lot of memory to convert to a bitmap. You

can save unrendered texture designs if you are not finished editing the

pattern.

Rendering a texture to a window

Rendering a texture to a window lets you immediately view the image. This

lets you make sure that the settings and the appearance are correct. You can

pause and resume the rendering process any time you want.

To render a texture to a window

1 Click Texture, Render To Window.

2 Click the Minimize button on the rendered window.

3 Click File, Save As.

4 Choose the drive from the Save In list box where you wan to save the

texture file.

5 Double-click the folder in which you want to save the texture file.

6 Type a filename in the File Name box.

7 Click the Save button.

To stop the rendering process

� Click the Stop button.

To resume the rendering process

� Click the Refresh button.


Rendering a texture to a file

Rendering a texture to a file lets you create a bitmap of the texture. This

process is slower than rendering to a window and does not let you preview

the texture.

To render a texture to a file

1 Click Texture, Render To File.

2 Double-click the folder in the Save In list box where you want to save the

texture.



To stop the rendering process

� Click the Cancel button.

� You can monitor the rendering process by observing the Status Bar.

Creating a tile pattern from a texture design

A tile pattern is created by placing smaller images of the same texture side

by side.

To create a tile pattern

1 Click Texture, Generate Tiling Image.

2 Click Preview, Test Tiling to view the image.

3 Click anywhere on the screen to remove the Pattern window that appears.

4 Render the tiled texture to a window or a file.

Saving texture designs in an unrendered format

You can save a texture in an unrendered format if you are not finished editing

the pattern. You cannot edit a texture once you render it to a window or to a

file.

To save a texture in an unrendered format

1 Click File, Save As.


2 Double-click the folder in the Save In list box where you want to save the

texture.



� Save preset textures with a different file name before you edit them,

otherwise you overwrite the preset texture.
