Thread Subject: Rotate the 'view' of images using imshow/imagesc

Hi all,

I've got an image (e.g. 100x200 pixels) and present the image using imshow or imagesc as landscape. How can I represent the image as portrait (thus rotated) without rotating the original image data?
I need to save memory, that's why I want to avoid creating new images due top imrotate every time.

Thanx in advance,

Kees

Wow, 100 x 200 and you're already constrained for memory? What are you running on? A cell phone?

I was going to suggest imresize but since you're already very very low on memory, I suggest you look at the DataAspectRatio property of the axes control.
Good luck (on getting a new computer).
