The five methods of passing images are: % +% % +% FILE - same thing as filename so it should be a NOP % +% IMAGE - passes an image and image info structure % +% BLOB - passes binary blob containining the image % +% STREAM - passes pointers to stream hooks in and does the hooking % +% ARRAY - passes a pointer to a Win32 smart array and streams to it % +% % +% Of all of these, the only one getting any real use at the moment is the % +% ARRAY handler.
