Hi,
I'm loading an image (with imread) and then I'm plotting some points on this images (with scatter and imshow for the image). The problem is, while using saveas to save the figure, im getting a completly different resolution. My image is 1360*768 pixels and is saved at 1200*900. I tried setting 'PaperPositionMode' to auto - but then I'm getting an 2384*1335 image saved. Also tried changing 'papersize' and 'paperposition' but still, i cant seem to have the figure saved at 1360*768. Does anyone know how to do this, I'v tried all the suggestions i found related to this subject but none worked.
Thanks.

Have you tried IMWRITE? Depending on the format you want to save as, you can specify the resolution in the command. You have to check for each format what the actual parameters are called (just use help imwrite to see specifics), but here is an example for a TIFF file:
imwrite(a, 'your_image.tif','TIFF','Resolution',[1360 768])
