View Full Version : C Wrapper dll SetFrameReadyCallback Image flipped

March 13, 2014, 10:53:41
Hello again!

I am using IC_SetFrameReadyCallback of the C Wrapper dll (tisgrabber.dll version with QT environment.
In the callback fonction, the image I get from the buffer is always flipped (vertically or horizontally), either showed by a QT windows or saved by Opencv.
I tried with IC_SnapImage and IC_StartLive, the image is correct.
It looks like that the image in the buffered is set to be flipped but I don't find how to get the flip property, or how to set it by the C Wrapper dll.
My camera is DMK 72AUC02.

Thanks in advance for any advice.

Best regards,

Stefan Geissler

This is normal. If the image provided from IC Imaging Control is forwared to OpenCV, the image is bottom up.

I suggest to flip the image with the appropriate OpenCV function.

Thank you Stefan for your answer, I will flip it by OpenCV function.
