How can I set the size of figure window, so all the figures can how the images only within the window?

Hi all,

I get multiple images from my code and they have different sizes, such as 30x10, 50x10, 70x10, and 90x10 as an example. If I am only interested in 60x10 in the center of all figures, can I crop the outsides of bigger images before the figures are created?

For example, I want 30x10 and 50x10 images just to be output, but 70x10 and 90x10 to be cropped. In other words, I want to look at the figures through 60x10 window and save them.

Is there any way to do that? I tried figure('Position',[left bottom width height]), but it just shrank the whole figure.

Any comment would be appreciated.

Thanks,

ROJO

newimage = YourImage;
if size(newimage, 1) > 60; newimage = newimage(1:60,:,:); end
if size(newimage, 2) > 10; newimage = newimage(:, 1:10, :); end

When doing newimage = YourImage, how can I read the image? I was doing something like A = contour(checkerboard), but it doesn't seem to do what I wanted. It doesn't even work for plot and imread.

Thank you,

Example:

YourImage = imread('peppers.png');

gimg = rgb2gray(YourImage);
[~, h] = contour(gimg);

axis off
frame_struct = getframe( ancestor(h, 'axes') );
contour_img = frame_struct(1).cdata;

newImage = contour_img;
if size(newImage, 1) > 60; newImage = newImage(1:60,:,:); end
if size(newImage, 2) > 10; newImage = newImage(:, 1:10, :); end
