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.
#include "ltwrappr.h"
virtual L_INT LMemoryFile::CompressBuffer(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.
| Value | Meaning |
|---|---|
| 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.
Win32, x64.
For an example, refer to LMemoryFile::StartCompressBuffer.
