ReadImageDocumentDesc Struct Reference
[Channel Ports Suite Callbacks (DEPRECATED Standard Suite)]

#include <PIGeneral.h>

Detailed Description

The document information, used by the Export, Filter, and Selection module parameter blocks.

Describes the document as a collection of channels and layers. The host provides a read port for each channel, so the pixel data can be read by using ReadPixelsProc in the Channel Ports Suite Callbacks (DEPRECATED Standard Suite).
