Re: [matplotlib-devel] Error building docs from the source
I can't reproduce this here. These sorts of CXX errors are usually
caused by distutils not rebuilding enough when things change. Can you
try removing the build directory, rebuilding matplotlib, and then
rebuilding the docs?

[matplotlib-devel] imshow zorder (patch for review)
Hi All, I have addressed what I think is a long-standing wart: zorder is mostly ignored for imshow(). (See e.g. http://old.nabble.com/Re%3A--Matplotlib-users--imshow-zorder-tt19047314.html#a19047314 ) The question is whether I should apply the attached patch. The worry is that someone is relying on the old behavior of images being underneath everything else. To a degree, this could be achieved by having the default image zorder be lower than everything else. Currently, imshow() creates images with zorder 1, which is pretty low on the hierarchy, but there may be something lower. (The artist base class default is 0, but the Line2D class bumps it to 2.) All tests pass with the change, and manual inspection of several of the pylab_examples don't show any difference before and after the patch. -Andrew diff --git a/lib/matplotlib/axes.py b/lib/matplotlib/axes.py index f628134..d23d1ce 100644 --- a/lib/matplotlib/axes.py +++ b/lib/matplotlib/axes.py @@ -1721,7 +1721,8 @@ class Axes(martist.Artist): if len(self.images)=1 or renderer.option_image_nocomposite(): for im in self.images: -im.draw(renderer) +dsu.append( (im.zorder, len(dsu), im) ) +dsu.sort() # re-sort with images now else: # make a composite image blending alpha # list of (mimage.Image, ox, oy) -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

Jae-Joon Lee wrote: Andrew, One of my worry is that this can results in inconsistent ouputs between backends. Your patch only affects backends with compositing capabilities.

Does the patch make this situation any worse? Eric I think it is often sufficient if we draw images at the bottom but respect zorders among images, and I guess this actually solves the issue of the original post. So, my inclination is to respect zorders between images by default (images still drawn at the bottom), and optionally with all other artists. Anyhow, I guess the cases affected by this issue is quite rare, and I'm actually fine if you submit the patch as is.

OK, sorry I linked to a motivating example that actually wasn't exactly the same as the use case I have -- I want a single image to play well with other artists' zorder. This patch does handle that scenario. I simply was too quick choosing this example out of the email history to justify the patch. So now the question for me is what is this option_image_nocomposite is so that I can generalize the patch to both when it's True and False. From the emails here, (my only knowledge on it so far) it seems it has something to do with the capabilities of the renderer rather than a run-time option selected by the user. I'll dig a little deeper into this option and see if my patch can deal with other cases, too.

Does the patch make this situation any worse? When there are multiple Images and render.option_image_nocomposite() is false (as in the ps backend ), the images are composited (rasterized) into a single image before it is passed to the backend. So, AS FAR AS the images are concerned, I think the ps backend does handle alpha correctly and the results are consistent between backends. And with the Andrew's patch, and if there are non-image artists between two images, the results can be different. For example, those non-image artists can be obscured by the foreground image in the agg backend, but will always show up in the ps backend. So, I think this is somewhat different issue than alpha being ignored in the ps backend. Regards, -JJ -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

So, if you're interested (all the following is GPL2):
*matplotlib patch*
In FigureManagerQT.__init__, added:
self.canvas.axes = self.canvas.figure.add_subplot(111)
In NavigationToolbar2QT._init_toolbar, added:
a = self.addAction(self._icon(customize.png), 'Customize',
self.edit_parameters)
a.setToolTip('Edit curves line and axes parameters')
Added the following method in NavigationToolbar2QT:
def edit_parameters(self):
from figureoptions import figure_edit
figure_edit(self.canvas, self)

(http://matplotlib.sourceforge.net/devel/coding_guide.html#licenses) but
we
have more licensing flexibility in a toolkit, though we prefer to keep
everything BSD compatible where possible. And of course you would need
to
agree to maintain it :-) but I think many users would appreciate a GUI

I was not aware of this license restriction in matplotlib... I fully
understand the motivation, of course, but still: I wrote all this on
my free time which means no PyQt4 commercial license, so it can't be
anything but GPL. Sorry...
I think you have overlooked a subtlety of PyQt4's license. The author of
PyQt4 wrote on the enthought-dev mailing list:
PyQt is GPL but has exceptions that allow it to be used with BSD code -
hence it's Ok for TraitsBackendQt to be BSD.
However, the exception imposes additional conditions which, to all intents
and purposes, infects the code with the GPL. To be fair to people that
should be made clear in any text.
It's still a good idea for TraitsBackendQt to use a BSD license because it
allows commercial (ie. non-GPL) users to use it without problems.

I think it might be worth contacting the PyQt folks (Phil Thompson) about
this. I think there might be some differences here because Phil was the
author of TraitsBackendQt and thus his efforts didn't quite fall under the
develop under a free license, your results needs to be GPL clause Qt/PyQt
have in their licensing.

Hi all,
Dave, you are absolutely right.
Last week-end, I found myself surfing on PyQt's website and I told to
myself: what about re-reading the license? (always a pleasure) And
surprisingly, I found out that anyone using the GPL version of PyQt
can release source code under a very permissive license (like MIT or
BSD) thanks to the PyQt-GPL Exception, as long as PyQt itself is not
part of the distributed package (otherwise the whole package has to be
licensed under GPL) - and with other little restrictions. It was a
surprise because I've read here and there a lot of things on PyQt
license and the general idea was if you write PyQt code without the
commercial license, your code *must* be licensed under GPL - I can
tell now that it's not true (to be absolutely certain about it, I even
asked to Phil Thompson to confirm this, and he did).
So, I switched all the code I was referring to in my original e-mail
to MIT license.
I guess now it could be integrated to matplotlib Qt4 backend?

Does the patch make this situation any worse? When there are multiple Images and render.option_image_nocomposite() is false (as in the ps backend ), the images are composited (rasterized) into a single image before it is passed to the backend. So, AS FAR AS the images are concerned, I think the ps backend does handle alpha correctly and the results are consistent between backends. And with the Andrew's patch, and if there are non-image artists between two images, the results can be different. For example, those non-image artists can be obscured by the foreground image in the agg backend, but will always show up in the ps backend. So, I think this is somewhat different issue than alpha being ignored in the ps backend. What's the motivation of the ps backend compositing (rasterizing to a single bitmap) multiple images? It seems it will, by design, preclude the use of non-image artists between two images. I guess the motivation is to reduce output file size. Maybe Axes.draw() should disable compositing in the scenario where a non-image artist is sandwiched by image artists and suffer the increased file size. -Andrew -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

I can't say about what the original intention was, but I guess one of the benefit is that you can have alpha compositing of multiple images. I personally think that no alpha support for images is a more serious issue than no alpha support for other artists like lines and patches. So, I'm +1 for doing the alpha compositing of images before passing it to the backends (that do not support the alpha compositing). However, as I said in my first email, I don't think there are much cases that this actually matters, while I'm also not sure about the benefit of having images above other artists like lines. Anyhow, as far as zorders between images are respected (in all backends!), it should be good. Regards, -JJ -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
