Hi,

I am having issues with using the imageview roi when imageAxisOrder is set to row-major. The values that get sampled are wrong. I made a test-file that I attached in which I compare the plots that I get from the roi in the original file, and a modified plot. (PS: you have to manually enlarge the plot in the red-custom plot window)

The axes values need to be different in order for the roi to display the correct image.

Moreover I get data values from where the rectangle would have been drawn if I did not have the row-major config settings.

So the question:

Is this a bug or is there another way to do this ?

Hi,

It isn't to do with the axes you pass into the getArrayRegion() method? Also, maybe take a look at this thread, it was a while ago but I think there might have been bug with axis ordering and I proposed a workaround. It might be the same problem you've having.
