Hi all,
I'm writing a small app that will effectively "scroll" a large image
generated procedurally. The image will have O(1000) words on it, some
rectangles, etc.. I don't need to interact with the words or edit
them in any way, just show them. My code is too slow right now.
Currently, the only way to draw text appears to be directly in a
stack, using one of the text methods (para, inscription, etc.). This
means every text block is a full-fledged object that must be managed.
I'm guessing that is really hurting performance when I want to draw
this many words (from reading the "rules" page).
For example, I can do:
Shoes.app do
para "foo", :top => 10, :left => 10
end
but can't do:
Shoes.app do
image 300, 300 do
para "foo", :top => 10, :left => 10
end
end
Any thoughts on adding text-drawing methods (preferably mimicking the
NodeBox API)? I looked through canvas.c to get some idea of how the
current text functions work, but I'd probably need some pointers on
where to start.
For a mock-up of the app (with lots of rectangles and words), check out:

There's a flag at the top that allows you to set either an "image" as
the container (no text), or just draw straight into a "stack".
Thanks!
