Saving Matlab figure(Imagesc) to JPG without White borders

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

Use this command from MATLAB - exportgraphics(gca,fname,'BackgroundColor','none')

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?

This works great. Thanks.

Answer 2

Yes, use imwrite:

imwrite(Subject_Assist_Quest, filename);

Do not save image analysis images as JPG or you'll be sorry. Use PNG.

Thanks got your point. I will save in PNG.
