L_BitmapFromYUV

Summary

Creates and allocates a BITMAPHANDLE from the YUV data. A bitmap will be created and stored in pBitmap, using the information (width, height, bits per pixel) and YUV data from the YUVIMAGE structure.

Syntax

#include "l_bitmap.h"

L_LTKRN_API L_INT L_BitmapFromYUV(pBitmap, uStructSize, pYuv, uBitsPerPixel, uFlags)

Parameters

pBITMAPHANDLE pBitmap

Pointer to the bitmap handle

L_UINT uStructSize

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

YUVIMAGE *pYuv

Pointer to the YUVIMAGE structure to be stored in pBitmap.

L_UINT uBitsPerPixel

Must be 8-, 24-, or 32-bits per pixel.

L_UINT uFlags

Unused, reserved for future use. Pass 0.

Returns

Value	Meaning
SUCCESS	The function was successful.
ERROR_BITPERPIXEL	`pBitmap` is not 8-, 24-, or 32-bits per pixel.
ERROR_UNSUPPORTED_CONVERSION	The YUV format indicated by YUVIMAGE.Format is not one of the supported values.
< 1	An error occurred. Refer to Return Codes.

Comments

This function supports only the following YUV formats:

L_YUV_420_888
L_YUV_YV12
L_YUV_NV12
L_YUV_NV21
L_YUV_YUY2

L_BitmapFromYUV allocates the bitmap and then calls L_SetBitmapYUVData.
