virtual L_INT LMemoryFile::CompressBuffer(pLBuffer)
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.
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.
