looking for an image viewer with pixel preview

this question is only indirectly connected to opencv. However, I hope its ok asking it. In my workflow I usually have a time series of images and I examine them using the image viewer Eye Of Gnome. However, recently I saw a usefull feature on a image viewer on the MacBook (I am sorry I forget to ask how the program was named). There was a little window with a large magnification of the section under the mouse cursor. Next to it the RGB values where listed.

Does anyone know a image viewer for Linux (Ubuntu 14.04) that allows me to examine image series similar to Eye of Gnome (easy and quick changing the image with one click) and adds a magnification tool with RGB values?

Thanks a lot.

You can do it using OpenCV ;)

You can do it using opencv built with Qt. imshow() has a ton of features with Qt. You can zoom in to a pixel level.

Interesting. I did not know about the many features of imshow. I use it only to get a quick look at my data during debugging. How complicated is is to add additional buttons like previous and next image in series? Or to add a statusbar with additional information (like image 5 /100, filename, ...)?

Also I am not interested in zooming in. I like a second windows with a magnification of what lies under the cursor and some text with RGB (or HSV) values next to it.

Thanks a lot.

I am sure you could do that with Qt, zooming to pixel level shows you RGB values of those pixels
