How can I view SWT Image while debugging?

Question

I added a breakpoint on my SWT-based application, and when Eclipse stops at it during a debug session I want to view the image referenced by an Image variable.

If I right click the variable and choose watch or inspect, all I see is what is returned from Image's toString method.

Is it possible?

You are generating that image on the fly..? Or why do you want to see it..? You can ask for width/height by `img.getImageData().width` if it helps you somehow.. — Sorceror, Jul 13 '11 at 17:37
I'm drawing it on the fly, and I'd like to see how it is in an specific point in time. — Mario Marinato, Jul 13 '11 at 17:50
I create a new GC passing my Image to it and draw a few dozens of squares and lines. That's it. — Mario Marinato, Jul 14 '11 at 04:14
You can create some method which will save the image to some uniquely name file on each step of you generating algorithm.. — Sorceror, Jul 14 '11 at 06:34
So you can use timestamp as a name of saved image and you'll get the progress in time as you want.. — Sorceror, Jul 14 '11 at 14:12

The debug views cannot "show" an image. The custom "Detail Formatters" can only return a string to be shown, not an Image or ImageDescriptor. It would make for a very nice extension though...

Don't you know if there's a plugin for that? – Mario Marinato Jul 13 '11 at 18:32

None that I know of... I'm not even sure how to do it... You probably want to add a new item to the popup menu of the Variables view. The selection seems to be an `JDILocalVariable`... but I haven't tried to decipher this... – Tonny Madsen Jul 13 '11 at 22:39

You could add a few lines of code that save the Image to your disc, then you can view the image.
