Unable to get the coordinates of ROI correctly

[HassanIqbal]

Hi all,

I am trying to obtain the grayscale values of pixels from a region of interest. The way I am doing is (1) converting the whole image into grayscale values and plotting an intensity graph.  (2) drawing an unflattening pixmap of the same image then drawing rectangle on the region of interest to get the coordinates. The problem is there is an offset in the coordinates of the intensity graph and the image means I am not getting the values from the ROI. Is there a way to remove the coordinates offset ?

Thanks and Regards

Hassan
