Note: These directions work in GIMP 1.2.0 for
Windows. It should work for Linux versions, but you may have to slightly vary
them because of different versions. (I do have Linux, but I've been downloading
an upgrade, and I need to get a USB hub to get my mouse working.)
Anyway, here's how: (It does not matter
whether you're using a Layer Mask or an Alpha channel.) (This one had me
stumpped for a bit.) (Also make sure your image's black on white. If it's the
other way around, Invert it.)
1. Open the image
(or make one) and use Layers-->Flatten Image.
2. In the Layers, Channels & Paths window,
right-click on the layer and choose Add Alpha Channel.
3. Right-click the layer again and choose Add Layer
Mask... and click OK.
4. Click on the left-hand preview image in the
layer list. (It's the one that looks like your image.)
5. Use Edit-->Copy in the image
window.
6. Click on the right-hand preview image in Layers,
Channels & Paths, then Edit-->Paste in the image window. Click to anchor
the selection.
7. You should now have a white image with
transparent text. Image-->Colors-->Invert it. Now, you should have a
transparent image with black text.
8. Go to Image-->Colors-->Threshold. For the
range, put in 1 as the first number and 255 as the second one. Click
OK.
9. Change the type to Indexed and save
it.
