  • start gimp
  • open screenshot, rename layer “target”
  • create new layer, transparent, “base”
  • move to bottom of layer stack
    • gimp advanced stroking preview layers two of them
  • select “target” layer, visibility off
  • select “base” layer
  • Image > Canvas Size
    • linked increase 80 pixels or so
    • offset: center
    • resize layers: All Visible **
    • resize
      • gimp advanced stroking canvas size layer boundary shell gaming 1
  • “target” layer, visibility on
  • create new layer, transparent, “over”
  • move “over” to top of layer stack
  • select “target” layer
  • Layer > Transparency > Alpha to Selection
    • optionally disable: View > Show Layer Boundary
    • gimp advanced stroking canvas size layer boundary shell gaming 2
  • Select > Grow > 8 pixels
  • select “over” layer
  • set foreground color to red
  • Edit > Stroke Selection >  solid 6 pixels

gimp advanced stroking canvas size layer boundary cutout to transparency and not background color

Now there’s a transparent gap between stroke and “target” layer

**

this has the effect of  changing “Layer Bounding Size”.  After resizing canvas need I also change Layer Bounding Size?  Why doesn’t it suffice that the top layer “over” has a larger Bounding Size (matching image size)?
