L_ClrConvertDirectToBitmap

Summary

Converts image data in a buffer from one color conversion model to RGB\BGR directly using built in algorithms, and sets the output as a LEAD bitmap.

Syntax

#include "ltkrn.h"

L_INT nDstFormat

Format of the output data. Possible values are:

Value Meaning
CCS_RGB [0x00] Color conversion is RGB.
CCS_BGR [0x0C] Color conversion is BGR.

L_UCHAR * pSrcBuf

Pointer to the buffer holding the input data.

pBITMAPHANDLE pBitmap

Pointer to the LEAD bitmap that will hold the converted data.

L_UINT uStructSize

Size in bytes, of the structure pointed to by pBitmap, for versioning. Use sizeof(BITMAPHANDLE).

L_INT nWidth

Width of pixels to be processed.

L_INT nHeight

Height of pixels to be processed.

L_INT nInAlign

Each scanline in the input buffer is a multiple of nInAlign bytes.

L_INT nOutAlign

Each scanline in the output buffer is a multiple of nOutAlign bytes.

Returns

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