Image Processing

[Yw Kim]

Hi.
I bought two DMK21BF04 models. I want to know how to get the image buffers. Is there image processing sample source? I use vc8 and IC 3.0.
Thanks.

Yes, there is sample code. Please have a look into the "samples" directory of your IC Imaging Control installation path.
Also the documentation shows how to access the image buffers.
The online documentation shows this too at:

Thanks for your answer.
But I want to perform continuous image processing.

I think my question is same as thisCLICK HERE (http://www.theimagingsourceforums.com/showthread.php?t=317441&highlight=buffer), however this sample code doesn't work in my environment(VC8).

Hello,

you can download from http://www.imagingcontrol.com/downloads/servicepacks/ the Service Pack 2 for IC Imaging Control. This installs the IC wizards for VS 2005. With this you can create a VC 8 application, that performs continuous image processing.

The trick:
Inherit an own class from GrabberListener. Call it e.g. "CListener"
Add this class to your grabber object.
Set the sink's snapmode to false: pSink->setSnapMode( false );
Now the frameReady() method of the CListener will be called automatically if a new frame is delivered and the previous call of frameReady() has returned.

Using the GrabberListener inherit class is shown here:

If the snapmode has been set to "false", then you do not need to call "snapImages", because the "GrabberListener::frameReady()" is called automatically.

The link you refer to in your post is for IC Imaging Control 1.41 or 2.1. In 3.0 there are some changes in the frame handler sink.
