LMemoryFile::CompressBuffer

#include "ltwrappr.h"

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.

Parameters

LBuffer * 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.

Returns

Value Meaning
SUCCESS The function was successful.
< 1 An error occurred. Refer to Return Codes.

Comments

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.
