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.
