I am using the following code to display an image on an axis in a Matlab GUI.
This is distorting my image. (There is text on the image which becomes difficult to read). However it seems that Matlab is trying to keep the dimension ratio, because stretching the axis in one direction does not change the output of imshow at all.
I have tried using XData and YData to manually resize the jpeg, with limited success. If I open the jpeg directly, it looks perfect, so it must be something Matlab is doing.
Does anyone have any suggestions? I don't really have a firm grasp on what Matlab is doing when I call the imshow function, so please point out of I'm completely off-base. Thanks.

It "shrinks to fit" the image into your axes. This means that it might subsample your image and lose some pixels, causing it to look bad. Try using a bigger axes, or maybe you can play around with the 'InitialMagnification' option for imshow(), or try using zoom().
