We could say that ;)

The main problem is, that I need my image to be scaled and rotated with interpolation but with non anti-aliased edges. For this my workflow was completely wrong. Let's say I start with high-res source image with detailed path around it.

What I did:
- selection inverted, background removed (alpha channel added), sharpen selection
- rotated image (here I've lost my sharp selection already)
- scaled image
- save as GIF

What I think of as much better workflow:
- scale and rotate image in one operation together with path
- position image on signature canvas
- path to selection + sharpen selection
- add alpha channel and remove background
- save as GIF

I don't know how to perform the first step.

Help needed - theme buttons look weird

You can NOT scale and rotate in a single action.

You can NOT scale and rotate in a single action.

Two more:
1. How about scaling both image and path/selection in the same operation?
2. How do you remove anti-aliasing just from the edges of an image/selection?

I "give up". After all it's not normal to require image edges to reamin pixelated for saving output image. Tank you all for your patience.

I dropped the whole GIF fight but I would still like to know, how to prevent edges to be anti-aliased using transparency!
