StdGetPic
Ptr destPtr ; where to store the picture definition data short byteCnt ; how many bytes to store
This is Quickdraw's low-level routine for obtaining picture- definition
information as it draws a picture (see DrawPicture). The default procedure simply copies data from an in-memory buffer addressed by a PicHandle to the specified destination buffer.
destPtr is the address of a buffer. Upon return, it will contain byteCnt
bytes of picture-definition data.
byteCnt is the number of bytes of picture-definition information you want to
retrieve. The buffer at destPtr should be large enough to hold this
much data.
Notes: Use StdGetPic only if your applicatin intercepts the Quickdraw This is a bottleneck routine that is frequently intercepted by application
is able to access a disk file, you can store and retrieve pictures larger than
the maximum limits set by Quickdraw.
