I’m trying to figure out a way to use the image.difference() method to only do the image subtraction on a particular ROI.
I’m able to save only an ROI
img.save("/temp.bmp", roi = [x0,y0,x1,y1], quality = 50)
… what would be the best way to do a image.difference() using that same ROI?
I can save off the old image easily enough (as seen above) … but how would I specify the ROI on the current image?
