Converts a Windows device independent bitmap (DIB) into a LEAD Technologies bitmap. When this function is completed, there are two copies of the image in memory: the original DIB and the LEAD bitmap. Freeing one will not affect the other.
Parameter |
Description |
pBitmap |
Pointer to the bitmap handle referencing the target LEAD bitmap. |
uStructSize |
Size in bytes, of the structure pointed to by pBitmap, for versioning. Use sizeof(BITMAPHANDLE). |
pInfo |
Long pointer to the Windows BITMAPINFO structure. |
pBits |
Long pointer to the DIB image data. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
This function updates information in the bitmap handle and copies the DIB image data into the LEAD bitmap.
Before calling this function, you must declare the LEAD bitmap handle and initialize it, specifying a height and width of 0. However, you should not allocate the bitmap. (If the bitmap is already allocated, you must free it and initialize the bitmap handle again.)
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
