Save image in specific resolution in Matlab

Question

I\'m trying for hours to simply output a certain plot in a specific resolution (320x240).

  xmax = 320; ymax = 240;
  xmin = 0; ymin = 0;
  figure;
  set(gcf         


        

Answer 1

There's an easier solution for this.

Saying you have your figure, gcf, you capture the frame and just use imresize to edit the object property cdata of your frame.

frame = getframe(gcf);
frame.cdata = imresize(frame.cdata,[240, 320]);

Then you can write your video using this frame, which now has the assigned resolution.

writeVideo(VideoObj,frame);

It works quite well.
