clipping paths, images and text are now all working in the new branch. Whew.
i renamed the 'RestoreCtx' class to 'EndClip', which makes its purpose
more evident.
check out the commit messages to see what other things i've tweaked
there ().
while trying to fix all the broken stuff i ran into a few issues and
fixed most of them.
Francesco, you've got my total respect for the great hacks you made in
clips and text -- took me a while to get it, but everything is really
neatly done. I've just repositioned some calls, but wow, great work. I
still don't know how you got the clips to work with save/restore, Cairo
just drove me mad and i ended up going back to your double-save hack,
which i still don't know how works (i just know that it does :)
one thing on my mind is to review the ShoebotDrawingArea so that expose
events don't run the script again (only scripts with a draw loop should
be animated/refreshed, but you'll see them being re-run if you resize
the window. They should just redraw the canvas, not run the script again.)
oh, and i got a Drawbot implementation almost there, just missing text
support. Woo! I'm a happy hacker tonight :)
please test some stuff if you feel like it. I'd love to be confident
enough to pull all these changes by the end of the week. Francesco, let
me know if you need help updating the lib imports.
cheers y'all

clipping paths seem not to work anymore either

colors library is broken as well with file-structure refactoring:
it used to do things like "from shoebot import Color as BaseColor" or
"from shoebot import RGB", and now it doesn't know where to find the
classes it needs

hi ricardo,
seems a lot faster indeed.
there are some things still broken anyway, two I noticed are:
-text is not working
- .fill and .stroke attributes for objects seems not to be working
anymore either. (e.g.sun_planet_moon_2.bot in nodebox examples
subfolder)

hey guys,
after the file structure refactoring, i couldn't help taking another
stab at finding the bottlenecks in the transform code.
it turns out that after
- removing individual path transforms, which breaks stuff like
rect(0,0,10,10, scale=(2,2)), but that won't be hard to put back again
and is a bit pointless anyway
- having the canvas directly process the drawables as Bot passes them,
instead of building a drawables stack that get drawn in the end of the
loop; then it applies the Bot transform matrix instead of the one in the
drawable
- and doing some cleanup on the canvas drawing code,
stuff looks quite a bit faster to me. My eee shows something like a 2x
increase in speed in the planets script that Stu sent to the list some
months ago.
if you feel like trying the new code, get it through
hg clone http://bitbucket.org/rlafuente/shoebot-filestructure
the script i mentioned is in examples/basic/transform/planets.bot (in
the main branch it's in examples/nodebox/transforms_stress_test.bot IIRC)
can any of you guys test it to make sure i'm not seeing things?
:r
