[Matplotlib-users] Intersecting polygons
Hi, I have a semitransparent plot that I rather like: [image: Inline image 1] I'd like to publish something like this in a journal which requires EPS figures. Unfortunately, EPS doesn't support transparency. How hard would it be to coax matplotlib (or another tool) to convert this semi-transparent figure into a non-semitransparent figure that looks the same? It would consist of more polygons, each of which has a constant RGB value in the transparent figure. I don't want to rasterize the lines, because I like zooming absurdly far into plots, and having them stay crisp.

I won't claim that this is an ultimate solution, but what I did a few times was to 1. Choose the svg backend, savefig the picture as svg. 2. Open in Inkscape and export as .eps. The result was satisfactory. Jerzy Karczmarczuk -- Introducing Performance Central, a new site from SourceForge and AppDynamics.

Re: [Matplotlib-users] Intersecting polygons
Thanks for these tips. It looks like some programs (like illustrator, and pdf2ps) are semi-smart about handling transparency when converting to ps. Both have their quirks (illustrator seems to mess up the bounding box, pdf2ps makes the text look worse/fuzzy). Is this the recommended/best strategy?

[Matplotlib-users] building matplotlib 1.3 on OS X 10.8.4
I built MPL 1.3 from source, all seem to go OK but I ran into the problem of not finding libfreetype.6.dylib when importing. On the web, I found references to this problem for builds on OS X. The solutions refer to a file README.osx, which is not present in the 1.3 distribution. The documentation (http://matplotlib.org/1.3.0/users/installing.html) also refers to this file and appears to be out of date. I have tried fiddling with the LD_LIBRARY paths, but have not come upon a solution. --Jim Boyle-- Introducing Performance Central, a new site from SourceForge and AppDynamics.

Re: [Matplotlib-users] [matplotlib-devel] I have a Mac!
with/without third party X I'm not quite sure what you mean by with/without third party X. If you are referring to Tck/Tk: I had an issue where MPL found the headers to freetype in /opt/local, but library in /usr/X11. Hilarity ensues. I *think* /usr/X11 showed up when I installed XQuartz, but I don't have a clean image to compare against. The with-X / without-X builds would be there to check that the default search paths are compatible with common environments. -matt -- Introducing Performance Central, a new site from SourceForge and AppDynamics.

Here's what I've done on recent versions of OS X. I'm not sure it's necessary to install everything below. Note that this only builds the native architecture for the version of OS X you are using, for example 64 bit for OS X 10.8, so there may be problems if you have to build matplotlib for a different architecture. In that case, you can add the appropriate CFLAGS=-arch blah parameter to ./configure download, unpack, configure and install pkgconfig curl -O http://pkgconfig.freedesktop.org/releases/pkg-config-0.28.tar.gz tar -xf pkg-config-0.28.tar.gz cd pkg-config-0.28 ./configure --with-internal-glib make -j4 sudo make install download, unpack, configure and install freetype curl -O http://hivelocity.dl.sourceforge.net/project/freetype/freetype2/2.5.0/freetype-2.5.0.1.tar.bz2 tar -xf freetype-2.5.0.1.tar.bz2 cd freetype-2.5.0.1 ./configure make -j4 sudo make install download, unpack, configure and install fontconfig curl -O http://www.freedesktop.org/software/fontconfig/release/fontconfig-2.10.93.tar.bz2 tar -xf fontconfig-2.10.93.tar.bz2 cd fontconfig-2.10.93 ./configure make -j4 sudo make install download, unpack, configure and install libpng curl -O http://hivelocity.dl.sourceforge.net/project/libpng/libpng15/1.5.17/libpng-1.5.17.tar.bz2 tar -xf libpng-1.5.17.tar.bz2 cd libpng-1.5.17 make -j4 sudo make install download, unpack, configure and install ghostscript curl -O http://downloads.ghostscript.com/public/ghostscript-9.09.tar.gz tar -xf ghostscript-9.09.tar.gz cd ghostscript-9.09 ./configure --with-x \ --x-includes=/opt/X11/include \ --x-libraries=/opt/X11/lib \ --disable-gtk \ --with-system-libtiff \ CFLAGS=-arch x86_64 -arch i386 LDFLAGS=-arch x86_64 -arch i386 make -j4 sudo make install Now python3 setup.py in the matplotlib directory should show that it found the libs you just installed.
