Outline marks after resizing (scale)

[JDRay]

Hello everyone!

When a layer is selected (alpha to selection) and I use the scale tool to resize it, it leaves marks/outlines of the original size.
How can I prevent this from happening?

Thanks for your help!

Could really do with more information on your workflow, a full screenshot also helps.

My best guess,
Alpha to selection > cut selection which leaves some semi-transparent edge pixels. Paste and scale leaves the edge pixels behind. example: https://i.imgur.com/5RCIF3t.mp4

A few ways depends on what is around the graphic. Alpha to selection then grow the selection by 2 or 3 pixels. Cut , paste, scale. example https://i.imgur.com/ceSnasr.mp4

If the graphic is all alone on its own layer then just resize the layer Layer > Scale layer.

This happens because you have partially selected pixels at the border of the subject when you do alpha to selection.
So when you transform the content of the layer, these pixels are "partially" transformed.
To avoid this, several ways:
- do not use any selection and scale the layer directly.
- make your selection where pixels are full transparent (away from the subject borders)

Seconded. As a rule, never use alpha-to-selection to act (paint, transform, etc...) on the same layer, because it partially selects the edge pixels, so you will get a partial action on these. Using alpha-to-selection on a layer to do something on another layer (fill, delete, etc...) is on the other hand often a good solution.
