Sizing image using gcf

I am trying to set my image to be 912 x 1140 pixels using:

set(gcf,'units','pixels','position',[0 0 912 1140])

However, when I save the .bmp image and check the properties, it says the dimensions are 912 x 821 pixels. Why is this happening / what are other ways for me to do this?

The command you provided does not resize the image. To resize image, use the “imresize” function. For example,

A = imread(‘peppers.png’); % read the built-in image
resizedA = imresize(A,[1140 912]);
imwrite(‘resizedPeppers.png’); % resizedPeppers.png is now 912 x 1140 pixels
