why do some blocks behind text darken?
« on: May 23rd, 2003, 8:57pm » |

For my text that's against the background, it's as if a bounding box, like blocks of set type, darkens around each letter as I use the applet. I'm using noBackground() and would like to keep that for the text.
Also, do I need hint(SMOOTH_IMAGES) every time I redraw a letter or shape I want to anti-alias?
Thanks,
RoBo

hint(SMOOTH_IMAGES) can be set once for all...
for the other issue: noBackground() means that the screen is not cleared at the beginning of a new frame, so each letter (which is, after all, a texture drawn with transparency) gets incremented opacity on the edges...
photoshop analogy: it's like taking a transparent layer with an antialiased black shape in the middle, and duplicating (the layer) x times...
make sense?

Thanks. That's still a little wierd. I thought I tried background(255) before, but it works now. On to digest your other suggestion...
