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"
#include "ltclr.h"

L_LTCLR_API L_INT L_ClrConvertDirectToBitmap(nSrcFormat, nDstFormat, pSrcBuf, pBitmap, uStructSize, nWidth, nHeight, nInAlign, nOutAlign)

Parameters

L_INT nSrcFormat

Format of the source data. Possible values are:

L_INT nDstFormat

Format of the output data. Possible values are:

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

Comments

This function works only for conversion to BGR or RGB color space formats.

Platforms

Win32, x64.
