Does buffer-to-buffer JPEG or LEAD CMP compression. Call this function to compress raw 24-bit BGR or 8-bit grayscale data using input and output buffers that your program allocates.
Parameter |
Description |
pLBuffer |
Pointer to the buffer that holds the data to be compressed. The data in this buffer must not be padded; so you should strip any padding bytes when loading the buffer. The BytesPerLine field in the bitmap handle may include padding. When getting data from a bitmap, it is better to calculate the bytes to get based on the Width and BitsPerPixel fields. |
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Note: You must call the LMemoryFile::StartCompressBuffer function before using this function, and you must call the LMemoryFile::EndCompressBuffer function to end the compression process. For a description of how these functions work together, refer to LMemoryFile::StartCompressBuffer.
