First, is this FloatCanvas 1 or 2?

so you are displaying letters, with different colored backgrounds?

do you mean ScaledText object?
SC.BoundingBox should do it, however, from the notes in the code:
"""
def CalcBoundingBox(self):
## this isn't exact, as fonts don't scale exactly.
"""
I guess I looked into that a bit at the time. Also, aside from scaling
issues, wx.DC is a bit weak with text extents -- it gives you a box
around the text, but it won't necessarily line up the "base line" right
if you put multiple chunks of text next to each-other.

.BoundingBox should have it, it just may not line up all that well.
So:
A) post some small sample code, and maybe I can see what's wrong.
B) if it really doesn't work well, you should be able to create your own
drawobject that has a clearly defined bounding box -- maybe every letter
would be a rectangle you draw, each one the same size, with the letter
drawn on top.
You could either start "from scratch" by looking at the Rectangle and
Text classes, or use a Group object, and put a Scaled Text object on top
of a rectangle.
