Defining Colors

• A color is stored as an unsigned integer

• A color is composed by 24 OR 32 bits (8 bit a channel)

• A color is computed as a HEX

Applying Filters

• Filters applied to BitmapData are more performing but DESTRUCTIVE

• You can apply only BitmapFilters (BevelFilter, BlurFilter, ColorMatrixFilter, ConvolutionFilter, DisplacementMapFilter, DropShadowFilter, GlowFilter, GradientBevelFilter, GradientGlowFilter, ShaderFilter*)

• (take a look at Image Processing library by Joa Ebert) http://blog.joa-ebert.com/imageprocessing-library/

Masking, Detecting Interacting

• Use BitmapData.threshold() to mask a color within a bitmapData

• Use BitmapData.getColorBoundsRect() to locate it

• THEN INTERACT! :D
