Re: [Matplotlib-users] font always the same in PNG
There are at least a couple of fishy things here. It doesn't seem to
find the Vera fonts that matplotlib installs in mpl-data. Did you
remove them, or perhaps the Ubuntu or Debian packagers removed them?
Then at least the default font would be correct (and not cmr10.ttf,
which is a very bad choice since it uses a TeX encoding).
As for why it is not picking up FreeSans like you request, my best guess
is that the default properties to not align correctly with it. This is
a major shortcoming of the font looking mechanism in 0.90 that was
addressed in 0.91. There is a possible workaround that is somewhat
painful. If you run the following command in a shell, you should see
all of the details about the given font:
fc-match -v FreeSans
Pattern has 27 elts (size 32)
family: Bitstream Vera Sans(s)
familylang: en(s)
style: Roman(s)
stylelang: en(s)
slant: 0(i)(s)
weight: 80(i)(s)
width: 100(i)(s)
size: 12(f)(s)
pixelsize: 12.5(f)(s)
foundry: bitstream(s)
hintstyle: 1(i)(w)
hinting: FcTrue(w)
verticallayout: FcFalse(s)
autohint: FcFalse(s)
globaladvance: FcTrue(s)
file: /home/mdroe/.fonts/Vera.ttf(s)
etc...
(I don't have FreeSans, so the above is for the next best match on my
machine, Vera Sans).
Now, if you specify the font as specifically as possible, you may get it
to grab your font:
rc('font',**{'family':'sans-serif','sans-serif':['FreeSans'],'weight':80,
'style':'Roman'})
(The above will need to be replaced with values for FreeSans, of course).
Let me know if that helps.
Cheers,
Mike

Did I miss something here?
Does it work if you put this into your matplotlibrc?

I've linked the output of fonts_demo.py to;
https://www.box.net/shared/static/o693hq3soo.png
Hmm. That font is definitely not Vera Sans. Something really odd is
going on here.
I can appreciate that goal -- and AFAIK it does work for other users on
Ubuntu 7.10 so there is probably just
some configuration problem here that we can hopefully get to the bottom of.
Do you have any customizations in your matplotlibrc?
Cheers,

Mike,
I've not made any other changes to matplotlibrc. In fact I only just now have
copied the one in /etc to my $HOME/.matplotlib directory. It still seemed to
pick up the /etc version as you'll see below, I guess coz I was sudo'd as
root? :) anyway...
Interesting the font search path seems to only include mpl-data fonts, but it
does seem to know about the ones in /usr/share/fonts/truetype/freefont. Then
fails to use one, so we're always back to cmr10. The output below was for my
test plot but it's pretty much the same (longer) story for fonts_demo.py I
tried copying all the freetype fonts into mpl-data/font and everything came
out FreeSansOblique. Still failed to find the correct font, but used
something
a little closer. What do you make of it?
I'll be away for a while but I'll check the list if I can.
Cheers,
Paul

Done in r5074. I don't have an older numpy lying around to test my

Re: [Matplotlib-users] How do you static link to freetype when building eggs?
John Hunter wrote: Instead of all of us going through the pain of figuring out how to build and link static libs for MPL, and PIL, and GDAL, and ???, why don't we just build against the nice Frameworks here: http://www.kyngchaos.com/wiki/software:frameworks I read your post and perhaps I am missing the obvious, but my basic question is: apple provides libpng and freetype with xcode which ships with their computers (an optional install from their cd) and these work fine with MPL, so why should we require an external dependency? I'd love it if Apple provided this stuff. Are they static libs? What versions do they ship them with -- I don't have OS-X 10.5, and I don't think I have them -- maybe I need to update XCode. freetype comes with X11, which is optional (though installed by default on 10.5). Also, I need libjpeg for PIL, but I guess that's not an OS-X issue. Here's the goal: Be able to easily build and distribute binaries of MPL (and other packages that require require similar libs). These binaries should: (1) Run on any OS-X 10.4+ system (10.3.9 would be nice too) with python.org's 2.5 framework build. (2) Allow packaging up with py2app, to get packages that will run on any 10.4+ system. As far as I know, the only way to do that now is to statically link against universal builds of all the dependencies that Apple does not provide on a stock 10.4 system. The problem is that there doesn't seem to be any standard source of Universal binaries for any of these libs (and the extra build flags required haven't made it into the source of the host projects). Also, it seems a bit silly to have a whole bunch of different packages all working hard to bundle in the same libs. I just built PIL against William's Frameworks, and it was oh so easy -- this after spending quite a few hours trying (and not finishing) getting the required libs built as Universal. We can only use Apple's libs if: They provide static Universal versions or The dynamic libs are there on All 10.4+ OS-X boxes. Maybe we can use more Apple libs for 10.5 only builds.

With mpl 0.91.2, the markeredgewidth property does not seem to have an

a minimal example:
