[vtkusers] Display OpenCV Image (IplImage) in VTK

[Samunda Perera]

Hi Anant,

I think i just found the problem, (not a bug).

Since opencv defaults to BGR memory style vtk reads these data as R<--B, G<--G, B<--R.

so displayed image does not appear as the real one.

however when input image is converted to RGB style  (ex: cvCvtColor(img,img,CV_RGB2BGR); ) looks ok!.

Regards,
samu

Dear all,

I have a pointer to a image stored in memory (example void* frame or similar data type obtained from opencv) .
How to display this 2D image data as a image in VTK window?

Thanks & Regards,
Samu
