In Photoshop, is there a way to warp an irregular image selected area, but with controllable number of sides (let's say 8), by these boundary lines instead of a general rectangle around the selection (with help of Illustrator if necessary)?

Yes. But without seeing the actual picture and usecase i can not describe a solution. I can not be expected to write a book on all cases and guessing game is not a good idea as you will just interject with no wont work in this situation because X. well either help us help you or expect vague answers. – joojaa Sep 18 '16 at 11:02

That is still just the same thing as a square. So do it as a square. – joojaa Sep 19 '16 at 19:04

Nope, it is an 8-like shape, skewed at the right. The red area is a pattern, imagine a ground with leaves, for the exercise. It doesn't matters the content, I am looking for a way to distort this "8" instead of cropping. – mike Sep 19 '16 at 19:15

Yes but you can treat it as 2 squares safely. – joojaa Sep 19 '16 at 19:28
I discovered this method in Illustrator while doing a curved label:
- Place a raster, embedded, not linked.
- Convert the raster to a Symbol (F8).
- Put your "arbitrary polygon" above the symbol.
- Press Ctrl-Alt-C or choose the menu item Object: Envelope Distort: Make with Top Object.
I think you already know about Transform-> warp and it's not giving satisfying result.
Only similar option I remember is a Puppet warp
Quick guide: 1.Select layer 2.go to edit->Puppet warp (triangular grid will appear on the object) 3. Add several anchors to object by clicking 4. Click and drag to move the anchor and portion of object
When you exit Puppet warp tool, anchors are lost
Hope this will help. More info https://helpx.adobe.com/photoshop/using/warp-images-shapes-paths.html

Puppet warp is far too complex and removes parts of the original object at the corners. I can't control it. – mike Sep 18 '16 at 9:33
