Try this,
set(gca,'position',[0 0 1 1],'units','normalized')
or you can try the imcrop
function.
문제
I want to save a frame as an image in png format with saveas command. Although my image's size is 640X480 (gcf), the saved images size is 1201x901 and spaces white color.(like a bold white border).So I want the image to be saved 640x480. I tried transparent background but it didn't work. How can I fix this problem?
F(j) = getframe(gcf);
fname='C:\...'
saveas(gcf, fullfile(fname, 'newImage'), 'png');

다른 팁
If you aren't overlaying any graphics over the image, then save the image data directly using imwrite
, rather than exporting a figure containing the image to png.
If you are overlaying graphics then the export_fig function (available for download on the MATLAB File Exchange) will automatically crop the whitespace around the figure. In this case use:
export_fig(fullfile(fname, 'newImage'), '-png', '-a1', '-native');
