Exploring more alpha
tools
You can now for example erase the content of the selected pixels to a
different color. Set the primary color for example to orange, and
right-click the erase tool (the big X), then select "Clear selected to
primary"
Other things to explore: you can also invert the alpha (the selection)
and replace it through the stored alpha window:


If you right-click on the alpha tools, a floating window will pop up,
for Alpha options. most of these options are also accessible from the
Alpha menu
Notice the alpha effects near the bottom:
- Paint on alpha
- Alpha glow
- Drop shadow
- Emboss by alpha
There's a lot you can do with just applying these in various sequences
and combinations, and inverting alpha occasionally.
For example, can you tell how this was created?

Hint: emboss by alpha, invert apha, alpha glow (with different primary
color) |
