Remarks

When this method is completed, there are two copies of the image in memory: the original DIB and the RasterImage it creates. Freeing one will not affect the other.

This method 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.

This method does not support signed images.

For more information on DDBs and DIBs, refer to Using DIBs, DDBs, and the Clipboard.
