Call for testing: Freetype module build system
Hi all, I wrote up a very simple wrapper to do textual annotations directly using Freetype. This allows, for instance, adding annotations to image buffers created by fixed resolution buffers, volume rendering, etc. It should, eventually, also allow us to make a subset of plots with colorbars without using Matplotlib. Anyway, I've already added freetype to the yt build system. Additionally, matplotlib requires it. So it *should* already exist on the system, although I've had to add some guesswork to get the yt build system (not the install script) to link against the freetype wrappers. I've bundled up the changes and attached them to this email. It would be amazing if I could have a couple people try unbundling these changes, updating to hash 2f9479b4f1dd, re-cythonizing and attempting a build. This process should look something like: hg unbundle freetype.hg hg up -C 2f9479b4f1dd cython yt/utilities/amr_utils.pyx python setup.py build_ext -i Testing this will help to make sure that we can push the new freetype module out into the wild, and use it more generally for annotating volume rendering, etc etc. You can see the (documented!) function as "annotate_image" which should be in mods, and which accepts a bitmap (as, for instance, output by write_image) as input. Any reports of success/failure would be great. Thanks! -Matt
+1 Works on my custom OSX 10.6 yt setup (own install of numpy, matplotlib, freetype I think, etc). I think this will be a really nice addition. One thing that might be nice as well is to instead of raising an error for the type not bing na.unit8, we could convert it like what is done in write_bitmap. That way if I were to read in a png with pylab.imread I could then just directly annotate the image that I read in. I've been playing around with a class that reads in all of the image (in this case volume renders) in a directory, enhances them (gets rid of flicker), and writes them back out to a new directory. That way the original image from the vr is kept intact before playing movie-maker and adjusting the images. Anyways, that's just a request and I can deal with it if it presents problems. Looking forward to it passing the tests! Sam On Tue, Dec 14, 2010 at 9:26 AM, Matthew Turk <matthewturk@gmail.com> wrote:

Just saw the _scale_image function in image_writer....ignore my request. On Tue, Dec 14, 2010 at 10:44 AM, Sam Skillman <samskillman@gmail.com>wrote:

Hi Matt, This is great. It installed with one problem (not related to the freetype additions) on OSX 10.6 with yt installed from the install script. I still had cython 0.12.1, and it gave me this error yt% cython yt/utilities/amr_utils.pyx Error converting Pyrex file to C: ------------------------------------------------------------ ... cdef void read_art_vars(FILE *f, int min_level, int max_level, int nhydro_vars, int grid_level,long grid_id,long child_offset, fields, np.ndarray[np.int64_t, ndim=1] level_offsets, ^ ------------------------------------------------------------ /Users/jwise/codes/yt/yt/utilities/_amr_utils/fortran_reader.pyx:213:47: Expected ']' Then I tried to install it on NASA's pleiades, where I have a custom install with Python 2.7.1, matplotlib 1.0, and numpy 1.5.1. When I installed matplotlib, it didn't play nicely with the system's freetype2 install (in /usr/include/freetype2), so I installed my own copy in my home directory (~/local). Can we have an option to point the setup script to look in a particular directory? John On 14 Dec 2010, at 11:26, Matthew Turk wrote:

Hi all, Thanks for the (so far!) positive (mostly!) feedback. John -- you should be able to set the base directory in freetype.cfg, just like png.cfg and hdf5.cfg. If you give that a shot, can you tell me if it works? Also, good to know about the 0.13 thing; cython 0.13 is now part of the installation script, but with any luck we can just ship the .c files for the most part. Sam -- I agree, we should have more unified image handling. As it stands, the bitmapping and whatnot is a bit annoying. I think in conjunction with the plot objects (and FRBs) we currently have, an ImageBuffer object would be nice. It could be created from floating point values, and then with min/max/colormap properties it could have a .bitmap property that would return a bitmap. Or something like that. I'm still thinking on it, but I believe we could do something useful with images. -Matt On Tue, Dec 14, 2010 at 10:51 AM, John Wise <jwise@astro.princeton.edu> wrote:

Hi John, Okay, I think this might be related to the way FreeType2 does its includes, which I think is a bit odd, and which I may not have implemented correctly in yt/utilities/setup.py. Is it finding the correct .h files, and then it's not able to identify the symbols? (At compilation, or during link?) Can you fiddle with the actual freetype includes in that setup.py, and then see if there's some kind of logical sense I am missing with the build? -Matt On Tue, Dec 14, 2010 at 11:10 AM, John Wise <jwise@astro.princeton.edu> wrote:

Hi Matt, I managed to fix this by installing my own copy of libpng. Previously I was using the system's copy in /usr. But there's also a copy of freetype2 in /usr. So the include paths had two copies of freetype2 in them with the system-wide (faulty) one taking precedence. I'm not sure why this didn't cause me problems with matplotlib.

Hi... I tested the version in the current tip. Super awesome. I made an amazing test image, but it has swears, so I will refrain from posting it to this family-friendly forum. If we can build a color bar on top of this, we can roll the PlotWindow out with no matplotlib necessary. Inline image generation on XT5! Great stuff, Matt. j On Tue, Dec 14, 2010 at 8:26 AM, Matthew Turk <matthewturk@gmail.com> wrote:
