Hi,
I want to export the RGB values directly from matlab figure (.fig). I don't want to store my image data as image files like .jpeg or .bmp.
Please look at the figure below, I need the RGB values.
Thanks for help

What do you want to export to ?
Are you creating a .fig just to avoid having to use saveas() / print() / imwrite() ? Because if you want to export in a different form such as a .mat file, the easiest time to do it is as you construct the graphics, not from a .fig file.

I'm using imagesc to scale my image data. And I need this scaled RGB values, when I export the scaled image for example as a .jpeg file all the RGB values are different. Do you know a good way to export or to work with imagesc?
Thanks for comments.

If you want to scale your pixel values, for some reason, use mat2gray().

If you want to export the scaled values I recommend you use the File Exchange contribution "freezeColors" and then get the CData of the image.
