Proper support for RGB images

[ivmartel]

RGB images can be loaded from DICOM and displayed but the contrast does not work on them.
RGB images should also be loaded properly from jpeg or png,

I do not think that making brightness / contrast adjustments to RGB images makes sense.
In particular, there is a discussion about applying "presentation states" to RGB images, and the answer (from David Clunie among others) is definitely not to do that:

Anyway, that does not mean that dealing with RGB images is working at 100%. There are things that still need to be modified. When you click with the mouse pointer in the image, the software obtains the value of the HU without taking into account the "samples per pixel" condition. The system reads the value corresponding to a very different position.
That should be changed to display the RGB value (or just nothing at all) for the proper X,Y coordinates. Apart from that, I do not think Hounsfield units make sense on RGB images.

About the presentation state, I understand what you mean Jose, I just need a bit more reading to make up my mind. In the meantime I activated it to see what it would be like.
