I had the impression that XeTeX had stopped development and that LuaTeX was 
the path forward.

I would never have thought ctypes would be a problem for speed/optimization and I never benchmarked the freetype-py. Not sure how to do that though.

Yes, and I recently discovered it may make things really slow in some cases.

You're right. I try to keep the very-low level to stick to the freetype implementation/type and the mid-level wrapper should use float everywhere (I may need to check that).


This + your comment on Google App Engine makes me think that freetype-py might not be so useful in the end. Anyway, I would gladly (try to) contribute to the new system.

Additionally, I just discovered that ctypes isn't available on Google 
App Engine, for obvious security reasons.  That sort of, unfortunately, 
makes it a non-starter for matplotlib.

Wish that weren't the case, but I think Google App Engine support is an 
important thing to keep going...

Exactly! I like that I can set text.usetex=True and add
\usepackage{fourier} and I *know* that my figures and document will look
the same.

That said, I've never been able to get the PGF backend to work well. Random
elements are pixelated. It's surely user-error on my end, but the usetex is
comparatively easy to set up.

As I state above -- I absolutely require One Font throughout my documents.
If it's a serif font, I use the fourier TeX package. If it's a sans-serif
font, I do the weird \sansmath voodoo (I still owe you a PR with an example
of setting that up). Point is, it works well.

Thanks for noticing that.  You are correct, and that underscore should 
be replaced with a hyphen.  However, I think in practice it's making no 
difference.  distribute automatically replaces underscores with hyphens 
before it does the PyPI lookup.  In any event, I've fixed this in e2e89eb.

> - Why include licenses for pytz and dateutil?

I just forgot to remove those during the refactor.  They have been 
removed in 441fe10.

As for the tests:  The warnings are all normal (it would be great to 
hide them, but I haven't invested much time to investigate that).

The first two failures are related to the PGF backend, and I suspect are 
failing because of a missing package in your LaTeX installation.  I've 
created issue #2097 and Cc'd you and Peter Wurtz (the PGF backend 
author) who may have some insight.

The last failure is a puzzler -- for some reason, the 
test_coding_standards test module isn't importing, though it was found.  
I'll let you know if there's more information I need from you about 
that, but at this point I'm not even sure how to investigate that one.

Thanks for working on this,
Mike

I looked at this a number of years ago, and just looked at it again 
today.  I think in general it's a better approach than what we have now 
in matplotlib, in that it's a thin wrapper around freetype rather than a 
"just enough to for what we need approach", which should make things 
more flexible in the long run.  It's a lot like what I have in mind.

However, I do have some concerns about it and I'd like to get a sense of 
your receptibility to these changes.

1) It's implemented in ctypes.  I'm not much of a fan of ctypes, as it 
has the potential to segfault in nasty ways if the API changes in any 
way from what was expected (which would normally be caught at compile 
time in a C extension).  I'm also concerned about the overhead of 
ctypes, given that there are already so many required optimizations in 
the matplotlib freetype wrapper to make it fast enough.  But I'm willing 
to hold judgement on that until some measurements have been made.

2) It's not Numpy-aware.  For example, it loads image buffers into 
regular Python lists.  This really should use Numpy for speed.

3) It exposes the fixed point numbers to Python as integers -- it should 
really return all of these as floats -- the user shouldn't have to know 
or remember which values are 16.16 and which are 24.8 etc.  It should 
just give floats.  Double precision (with 52 bits in the mantissa) is 
enough for any of these 32-bit fixed-point values. I think that's just a 
remnant of older systems and needing to run on hardware without an FPU 
that doesn't need to be brought forward into the Python wrapper.

4) It should have another layer to handle the decoding of SFNT tables in 
a consistent manner.  I know the sfnt-names.py example does this, but 
that should be built into the library.  There are certain places where 
hiding the details of the underlying font file is a good thing -- and I 
think one of the reasons freetype doesn't do this is the lack of a 
standard Unicode type in C.  We don't have that problem in Python.

I think all of these are fixable by adding another layer on top, with 
the exception of (1) of course.  Maybe it makes sense to build that 
intermediate layer, adapt matplotlib to it, benchmark the ctypes issue, 
and if necessary reimplement the core using C/API.

By the way, Behad is considering a refactoring of the library and it might be worth to interact with him (on the harfbuzz list) to see how this could ease a python wrapper (if you intend to use it of course).

That example is very helpful.  Thanks.  I should add to the MEP, for 
those that are not aware, that even though Harfbuzz is a part of the 
Gtk/Gnome/Cairo ecosystem, it is a very standalone library itself, and 
is the closest to "works everywhere with minimal requirements" of any of 
the available options.  I should definitely clarify that even though 
there are many options for font layout libraries, including both 
cross-platform/open source and closed-source-vendor ones, Harfbuzz could 
be the "one to rule them all" so we wouldn't necessarily need to wrap 
all of them.

Yeah -- I need to make that more explicit.  I think MEP14 needs to 
consider the *possibility* of adding rich text support down the line so 
that the API can support it, but the details of how we might actually do 
that should be postponed for another MEP.  It's already a lot to bite 
off as it is.  Does that make sense to you -- are there things in the 
proposed API that would inhibit that from being added in the future?

Mike

That's an interesting idea, that we should definitely ruminate on. That 
still doesn't address the Unicode issues, which are really complex to 
get right -- I'd really rather depend on something else for that.  But 
what you suggest might be the best way forward to improve the built-in 
rendering for a good fraction of users that don't really care about Unicode.

Right -- and I think moving to XeTeX for the "usetex" backend, which is 
now pretty widely available, might be a good improvement on that front.  
I still don't want to reimplement all of that, if I can avoid it.

I'm not sure that's realistic.  The usetex backend gets a great deal of 
use, and I don't think it's only because it handles multiline text 
better -- it's also the easiest way to make the text match that of a 
larger TeX document in which it's included (though the new PGF backend 
goes some way to helping that in an entirely different way).  It might 
be worth collating a list of reasons that users are using "usetex" to 
include in the MEP -- if we can address them all in another way, great, 
but if not it's not too difficult to keep something that already works 
fairly well working.  The problem I have with it is not really that it 
exists, only that it has tendrils all throughout matplotlib that could 
be better localized into a single set of modules.

Thanks.  Keep em coming!

I uploaded a binary installer for MacOS X, 64-bit python.org python 2.7.
I built it using numpy 1.7.1. This version does not include pytz, 
dateutil or six, but the included ReadMe says they are prerequisites and 
suggests installing them with pip.

The tests showed more problems than usual. I have appended the whole set.

A few questions:
- Why does setupext.py's dateutil finder have this:
   return ['python_dateutil']
when the package is called python-dateutil (hyphen instead of 
underscore)? If it is intentional, it might be worth noting with a 
comment.
- Why include licenses for pytz and dateutil?

For the free type wrapper, maybe the freetype-py may be of some help:
http://code.google.com/p/freetype-py/

I did not wrap all the freetype library but it already allows a fair amount of font manipulation/rendering.


For unicode/harfbuzz, I've found this example

https://github.com/lxnt/ex-sdl-freetype-harfbuzz

to be incredibly useful to understand the (poorly documented) library. The strong point of harfbuzz is to have no heavy dependencies (compared to pango for example). By the way, Behad is considering a refactoring of the library and it might be worth to interact with him (on the harfbuzz list) to see how this could ease a python wrapper (if you intend to use it of course).


In the current draft, you're speaking of rich text but I found no reference for a possible markup (or equivalent) to specify the different font, color, boldness, etc.

nice writ-up and thanks for workign on this.

One idea (alternative?) would be to put more effort into the
"mathtext" renderer. TeX itself, of course does an outstanding job of
laying out text, paragraphs, etc. I'm assuming that the core stuff is
already in mathtext, so adding better support for regular old non-math
text would be a less-than-huge deal. And we still wouldn't need the
full how-to-split-pages and all that code for MPL.

Not sure about properly handling unicode issues, though modern TeX
does support unicode.

With a fully-function mathtex, it could be the default (only?) text
layout system for MPL, simplifying things quite a bit.

... just a thought.

I agree -- adding them to the binary package is the way to go here --
it's  packaging issue, not a development or building issue.

I can't imagine it would be hard to write a little script that
includes them all in one mpkg.

Should the code that's shipped with MPL be build-able with PIP? But
the harder issue is third-party dependencies that we expect the system
to provide: libpng, libfreetype, ....

On the building side, I'd really like to see more support for this --
the Linux package managers handle it OK on LInux, but there is no good
system for Windows or OS-X.

I'm taking a look at gattai:

http://sourceforge.net/projects/gattai/

Mostly for the Mac, but it does support Windows and linux as well.

I'm not looking at Windows right now, as Christoph's repository gives
me all I need -- which makes me think:

Christoph, do you have a build system for all those that might be a
good basis for a multi-platform solution?

I've drafted a MEP with a plan to improve some of the text and font 
handling in matplotlib.

I'd love any and all feedback.

OK, that worked. I uploaded Windows binaries, which include all test files.

It's really just that the matplotlib source no longer includes them.  
Binaries can be built however we want them to be.  Not knowing how the 
.dmg is put together, is it possible to add pytz, dateutil, pyparsing 
and six to the dmg during its creation?

Right -- and we're not using pip (because we can't) to handle our C/C++ 
dependencies, many of which we continue to ship with matplotlib.

No worries.  I'm certainly guilty of not always being able to keep up 
with the firehose myself.  This work was done as part of MEP11 ( 
https://github.com/matplotlib/matplotlib/wiki/MEP11) 
<https://github.com/matplotlib/matplotlib/issues/2092>, and searching 
the mailing list with "MEP11" as a key should help you find the rest of 
the discussion.  It was pretty unanimous to move to not including these 
dependencies -- I certainly understand that different communities and 
platforms have different expectations, though, and if we want to find a 
way to include the dependencies in the Mac installer, I'm not opposed to 
that, but I would like to find a way to do it that only affects that one 
particular use case and not all the others (i.e. something external to 
or at least optional within the current setup infrastructure).

These are tricky, as we want to continue to support earlier versions of 
Numpy.  (Officially, we support back to 1.4, though only 1.6 and later 
is getting regular testing).  Last time I looked, there wasn't a good 
way to do this without a lot of #ifdefs that would just make the 
maintenance more complicated.

However, perhaps for the next major release we should consider dropping 
Numpy < 1.5 and fixing up these deprecation warnings.

Must be a problem with the upload.  I'm reuploading it now.  I'm not 
going to bother upping the version -- it's just the result of a failed 
transfer apparently.

I have been following that thread with great interest. If such a repository becomes available I do intend to contribute to it.

For the record:
- I prefer static libraries
- The wheel format sounds very promising. But until we have it and until pip supports it, my suspicion is that it's not worth trying to automate dependency handling, and we should live with mpkg binary installers.


In the short term I'd be happier if matplotlib continued to support including dateutils, pytz and six. It is not ideal to include dependencies, but convenient and pragmatic. Failing that, i think we should ask users to install pip and use pip to install dateutils, pytz and six. I fear it would be too much work to provide binary installers for pytz, dateutils and six because we would need to make different packages for different versions of python (which feels silly for pure python packages!), keep them up to date, find somewhere to serve them...

In the long term, I hope wheel format will allow us to use pip to install matplotlib, in which case it will handle dependencies and we need not include them.

If the binary installers are available (and easy to find), not such a
big deal -- this is teh case with Christoph's repository for Windows,
for instance.

Russell, have you been following the thread I started on the pythonmac
list? We really need a way to deal better with binaries on the Mac,
including dependency handling.

Note that supposedly the "wheel" format is coming (soon?), and after
that support for binary wheels by pip.

Of course, none of that helps right now...

Thanks for the update.

The Mac version built fine, but I saw several warnings. The only one I'm 
worried about is use of a deprecated Numpy API:

It looks like the ability to include pytz and other dependencies in 
binary distributions has been removed?

Is this really what we want? In the past we always included them. 
Excluding them certainly makes sense if using pip or a similar installer 
that can handle dependencies, but that is not the case for binaries.

I guess we could serve the associated packages (pytz, dateutil and six), 
or if they can be installed by pip, ask users to install those. But 
users using binary installers may not even have pip available, so it's a 
big initial hurdle.

I'd personally be happier reverting to the old system. Sorry if I missed 
a discussion on this.

Sorry, but that tarball does not include setup.py and other files. It is 
only ~25 MB.

Hi all,

I just wanted to let you all know that Hans Petter Langtangen,
well-known author of books on scientific Python and long-time champion
of these tools at the University of Oslo for many years, has arranged
for a donation of $10,000 to support matplotlib's development.

Hans Petter is the Director of the Center for Biomedical Computing at
Simula (http://home.simula.no/~hpl), where a number of projects use
Python as key elements of their research, the Fenics platform being
among the most well-known (http://fenicsproject.org).

We have now confirmed that these funds have been transferred to the
NumFOCUS donations account, where Michael and the rest of the team can
make use of them.

I wanted to publicly thank Hans Petter and Simula Labs for
persistently jumping through the necessary hoops to make this
possible, and to Leah, Travis and Anthony at NumFOCUS for managing the
receiving side of things.

Ok, folks.  1.3.0rc2 is here:

While annoying, I think these are benign --- the 2to3 tool is tripping 
up on these docstrings.  Overtime, the docstrings will get rewritten in 
numpydoc format and we *might* see these go away.
