L_ChangeFromDIB

#include "l_bitmap.h"

L_INT EXT_FUNCTION L_ChangeFromDIB(pBitmap, uStructSize, hDIB)

pBITMAPHANDLE pBitmap;

/* address of the LEAD bitmap handle */

L_UINT uStructSize;

/* size in bytes, of the structure pointed to by pBitmap */

HGLOBAL hDIB;

/* DIB handle to be changed */

Changes a Windows device independent bitmap (DIB) to a LEAD bitmap. This function results in only one copy of the bitmap, and it invalidates the DIB handle.

Parameter

Description

pBitmap

Address of the LEAD bitmap handle.

uStructSize

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

hDIB

The DIB handle to be changed.

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

Comments

Before calling this function, you must declare the LEAD bitmap handle, but you should not allocate the bitmap, because the new bitmap handle will point to the previous DIB data after the function is called. (If the bitmap is already allocated, you must free it.)

This function supports the standard DIB formats (BI_RGB and BI_BITFIELDS) as well as some FOURCC (Four Character Code) formats that some capture cards output.

These are the FOURCC that LEADTOOLS supports at the moment:

YVU9 (YUV9), I420 (YUV12), YUV2 , YV12 , IF09 , IYUV , UYVY , cyuv, YUY2, YVYU, Y41P, Y211, Y41T, Y42T
