??? DESCRIPTION OF THE "ChannelReadPort" STRUCTURE ???

[_Chavdar_Papazov_]

Hi,

would someone tell me where to get the definition of the "ChannelReadPort" structure from?
I am writing a Photoshop Plug-in, that should read image lines from an image opened in Photoshop. I want to use the "ReadPixelsProc" function. The first argument of this function is a "ChannelReadPort" variable. I can't find anything about this structure, neither in the docs nor in the header files of the SDK...
Or there is another function to get the pixels of an image opened in Photoshop?
Can somebody help me?

Thanks.
Chavdar

You must have a really old SDK. It is defined in PIGeneral.h
