XnView Software

In my Windows XP version 1.96.5 there is a menu item for IMAGE - between View and Filter.

I'm a new user - XnView 1.96.5 for Windows. I searched the Help files and Forums but didn't find an answer to this question. Is there any way to make a selection using a circular or oblong selection instead of the default rectangles? Say I want to sharpen an eye that is circular, how can I do this ...

Thanks for the quick reply, Helmut. I missed that in the Edit menu. I will give it a try. I believe that the 3:2 ratio is approximately the right size for a 4x6 inch print.

I searched the Forums but didn't find any way to crop images into standard paper ratios, i.e., 4x6", 5x7", etc. I was really starting to like XnView until I came across this omission. Am I overlooking something?
