Thread Subject: Displaying 3 channel data of values larger than 1

Hi all,

I've got 3 channel data (call it pseudo RGB, e.g. 100x100x3) with values larger than 1.
When I push this image to imshow or imagesc it complains that it cannot be displayed since values are <0 or >1 (no true color data).

How can I solve this problem, in other words, how can I display the image scaled between min and max values without affecting the original data.

thanx in advance,
Kees

If you don't want the scaling to effect the original you can either make a copy of the array or apply the scaling inline to the call to imagesc e.g.

imagesc((A-min(A(:)))/(max(A(:))-min(A(:))))

Thanx for reply.

In the solution you mentioned, there is still an affection of the CData stored by the image-handle.
Isn't there a solution using colormaps?
