Hi,
I am using imagesc to plot color maps in matlab. While saving as JPG and Figuire it gives white space around the image. Is it possible to save without white space?
imagesc(Subject_Assist_Quest);
set(gca,'YDir','normal')
axis off

When I try this I get: "Warning: Background transparency is not supported; using white instead. " So far I haven't found a workaround.

You can ignore the warning. Is white not OK? Why are you having transparent pixels anyway?

Yes, use imwrite:
imwrite(Subject_Assist_Quest, filename);
Do not save image analysis images as JPG or you'll be sorry. Use PNG.
