Hi everyone,

I'm trying to compensate for projection effects that happened during the off axis recording of an image. The result is an elliptic projection instead of a regular circle. So I'm looking for a way to stretch that image along the horizontal axis by a certain factor. How can this be done? Any advice is appreciated. Thanks.

Sure, just send in a new XData property to imshow:

grayImage = imread('moon.tif');
[rows columns numberOfColorChannels] = size(grayImage);
subplot(2, 1, 1);
imshow(grayImage);
newWidth = [1 5 * columns]
subplot(2, 1, 2);
imshow(grayImage, 'XData', newWidth);
