1.a. Your animated gif is exactly what I meant by "virtual frame", I'm not sure if name is ok though, maybe image transform frame?
1.b. To simplify wish I just meant same basepoint option as frames have, but of course free-selectable would be best
1.c. That's best option.
2. I will look for free animated gif tool to show, but in the meanwhile I hope description will be ok:
- Place frame, put image inside.
- Adjust frame proportions and size to fit with text nicely.
- Double click on the image, now to crop you have scale with alt+up,down but that way only right and bottom of the image will be cropped (as basepoint is set to top-left), so you have to move the image to the left and scale again to get proportional cropping right. Usually I repeat it 3 times. Here center basepoint as default would be better, but virtual frame scaling using e.g. mouse+alt+shift (or some shortcut keys) and selecting basepoint would be best solution ever.
Same thing with rotation, it's pretty awkward to rotate image with top-left basepoint...
3.b. Button+document option "reset image scale after substitution" as default
Thanx alot for supporting idea!
