get image data in vc++

[scottsl]

hi  all,

i'd like to use vc++ to process image data (read/modify pixel values, display the image, etc.) through imaq library.

sample code:

// get the frame

imgGrab (Sid, &ImaqBuffer, TRUE);

// display it using imgPlot

imgPlot ((GUIHNDL)ImaqSmplHwnd, ImaqBuffer, 0, 0, AcqWinWidth, AcqWinHeight,

CanvasLeft, CanvasTop, plotFlag);

imaqBuffer ist the buffer for storing image data, which was declared as follows:

static

 char *ImaqBuffer=NULL; // acquisiton buffer

How can i get the image data from "ImaqBuffer"? (how to get the buffer size?)

thx a lot!

Hi Scott, wit installing NI-IMAQ you will get examples.  You can find them in C:\Programme\National Instruments\NI-IMAQ\Sample\MSVC\Grab I think they will answer your question.

Thanks, Rebecca
