This is the first icon where I worked very hard to make it visible to all sizes. The original icon for this program, a must for any photographer who uses Linux, is poorly integrated with the GNOME desktop.
It was created with Inkscape, the sources can be found inside the store.
The dimensions are:
16x16
24x24
32x32
36x36
48x48
128x128
256x256

Thanks to DanRabbit for help me to develop this icon!
