Exception ERROR in ColorSpaces: interactiveColorDetect.cpp

[PrimusSPS]

Current code throw an exception error when cursor is moved in the "placeholder" area. It can be fixed by updating the if condition on line 12:

FROM:
LINE 12: if( event == EVENT_MOUSEMOVE)

TO:
LINE 12: if( event == EVENT_MOUSEMOVE and (x<img.rows and y<img.cols))

Thanks for the fix attempt. The reported crash is real, but I don’t think this condition is correct yet.

In the mouse callback, x is the column coordinate and y is the row coordinate, so the bounds check should be against img.cols for x and img.rows for y. The current PR uses:

x < img.rows && y < img.cols

which is swapped. It only appears to work here because the image is resized to 400x400, so rows == cols.

Could you please update it to something like:

if (event == EVENT_MOUSEMOVE && x >= 0 && x < img.cols && y >= 0 && y < img.rows)
