How to make same ROI?

I draw roi using impoly in figure plotted using plot command. I get the coordinates using getposition.(red line in figure1,see attached). I use this coordinates to draw mask using poly2mask which is rotated and looks rotated and mirror inverted in shape( see attached, figure2).

How can i make my ROI and mask look similar( no mirror invertion and no rotation) and same size?

Any help would be much appreciated.Thank you.

Make sure while using poly2mask(x,y,m,n), m and n are same dimension as image otherwise image size will change. Check the script for the reference.
