dmj's graphics tips: backglow text

Here's a quick little effect that I've used to make small text more readable at small sizes on highly textured backgrounds. Make a new image and create a text object:


Now copy the floating object onto the clipboard. (You could re-create the text again later, but the clipboard is a convenient place to copy it so you don't have to re-create it.) At this point, if you like, you can fill the text with a texture; this is particularly effective with large type. Once you've done that, combine all the objects with the base.
The next step is to switch to the alpha channel, by clicking the little alpha button in the lower right corner of the main window. Paste your copied text onto the alpha channel. If your text is black (as mine is) you'll need to invert it; whatever you do, though, the text needs to be white. Go ahead and combine this text object with the rest of the alpha channel.


Now blur this alpha channel, using the Gaussian Blur effect. (Substitute other blurs for different flavors of the effect.)


Switch back to the image (the alpha button again) and copy this to the clipboard; paste it onto your textured background:


You can change the glow color by changing the background color of the image before you combine the text with it (right at the beginning). If you don't want the background texture to show inside the edges of the text (particularly if you've filled your text with a texture) put an extra copy of the text behind your fuzzed object, but filled with black (or some other color).
