Chapter 4 Known Issues

The following table lists the issues that have been identified but not fixed in this release:

Issue # Description Impact Workaround

COM-369 Decompressing single frame JPEG image calls registered decompression callback function with isLast=true twice.

This defect applies to Merge DICOM C/C++ Toolkit.

Registered decompressing function will receive the second isLast=true callback with data length, data pointer being NULL.

When seeing isLast = true, data length = 0 and data pointer = NULL, just return MC_NORMAL_COMPLETION.

COM-628 When user registers a decompression function and starts retrieving encapsulated data from a multi-frame image without offset table, the toolkit doesn't set isLast flag at the end of pixel data when calling the registered decompression callback.


This only happens when there is no offset table for multi-frame image. User that needs to receive the entire pixel data before invoking a custom decompressor would not notice the end of data event. That means user does not know when to start decompressing.

Note: As stated in User's Manual, Toolkit requires user's registered decompressing function to incrementally decompress and returns data constantly. If user must gather all pixel data before decompressing, then it is already breaking the protocol. Nevertheless, the toolkit may wish to revise this behaviour.

Use MC_Register_Callback_Function to receive the pixel data in user space. User can then trigger decompression with all data in user space.

10


COM-631 C toolkit opens/closes temp file too often that impacts performance when LARGE_DATA_STORE is set to FILE


When using temporary file as pixel data storage, large streaming file (gigabytes) can cause the writing of a chunk of data to be very slow due to the seeking operation to end of file after every fopen call.

1. Set LARGE_DATA_STORE = MEM, or2. Use MC_Register_Callback_Function for pixel data tag and manage the pixel data by saving each chunk in a user controlled temporary file. User needs to close the temporary file only after the last chunk of data is written.

COM-645 Toolkit fails to pad odd size pixel data when total number of MCdata bytes are odd

This defect applies to Merge .NET/C+ Toolkit.

When total number of bytes is odd, user is calling MCattribute.setValue(MCdataSource, length) with a rounded up even length. However, user's MCdataSource.providData can return MCdata with odd size each time. At the end, the toolkit may receive odd size total bytes. When streamed out, the toolkit does not pad and results in even attribute length but odd size value.

User can pad the last MCdata buffer to even to match the setValue() parameter.

COM-669 Missing JPEG-LS compressor opcode from Pegasus.


Cannot compress an image using JPEG-LS transfer syntax.

Receive a copy of the JPEG-LS opcode .dll/.so after purchasing license from Pegasus. Manually edit mergecom.pro to insert license information for JPEG-LS.

COM-719 Solaris Sparc 8 toolkit hangs in MC_Read_Message when network cable is unplugged.


When network cable is unplugged for testing, MC_Read_Message is not returning after timeout period.

None. Do not unplug network cable.
