L_LTFIL_API L_INT L_CompressBuffer(pBuffer)

pointer to the input buffer

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
pBuffer	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

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

Comments

Note that you must call the L_StartCompressBuffer function before using this function, and you must call the L_EndCompressBuffer function to end the compression process. For a description of how these functions work together, refer to L_StartCompressBuffer.
