script-fu Bevel questions
All,
I'm trying to create some buttons that are beveled along the edges, have
an optional "pressed-in" look, etc.
I'm basing my script-fu work on the script-fu-button00 function (file:
beveled-button.scm). I'm understanding everything in the example code up
until the point that it makes a call to: plug-in-bump-map()
This is the call that takes the bump-map image and overlays it with
another image (terminology might be off, sorry).
But what I dont understand, is how, or which parameters, are setting the
shadowing of the pressed in look (or the not pressed-in).
I don't understand what is causing the 2 strips of dark bevel to appear.
I've commented out the code to where it stops drawing at that point so
that I can look at the layers, but I'm still not seeing it. I've looked
at the plug-in code, and am still not seeing what is causing the shadowing
effect.
In short:
What is causing the dark portions of the bevel (one horizontal,
one vertical)?
Thanks
Matt
