[matplotlib-devel] wx.AlphaPixelData() is failing on windows server 2003
wx.AlphaPixelData() is failing on windows server 2003. The sample code is given below. The same is working fine on windows xp. what could be the reason? import wx class Size(wx.Frame): def __init__(self, parent, id, title): wx.Frame.__init__(self, parent, id, title, size=(250, 200)) absFilename = "C:\Python26\Lib\site-packages\win32\Demos\images\smiley.bmp" bmp = wx.Bitmap(absFilename, wx.BITMAP_TYPE_BMP) pixelData = wx.AlphaPixelData(bmp) if not pixelData: print "error" else: print "fine" app = wx.App(False) Size(None, -1, 'Test') app.MainLoop() -- View this message in context: http://old.nabble.com/wx.AlphaPixelData%28%29-is-failing-on-windows-server-2003-tp27847892p27847892.html Sent from the matplotlib - devel mailing list archive at Nabble.com. -- Download Intel® Parallel Studio Eval Try the new software tools for yourself.

Re: [matplotlib-devel] wx.AlphaPixelData() is failing on windows server 2003
Is this bug related to matplotlib? (i.e. does it happen only when matplotlib is imported?) If not, you may have more luck on the wxpython mailing list.

It looks like you've done a pure-wx test, so it is a wx issue. > If not, you may have more luck on the wxpython > mailing list. yup, that's the place for it -- I suspect that windows server 2003 is old enough that it may not have the newer alpha-supporting drawing stuff -- that may be a dll that you could add, though. You'll get a better answer on the wxpython-users list. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R(206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception chris.bar...@noaa.gov -- Download Intel® Parallel Studio Eval Try the new software tools for yourself.

[matplotlib-devel] Inconsistent behavior in plt.hist
I get inconsistent behavior when plotting multiple sets of data with plt.hist. Here's a quick example: >>> import numpy as np >>> import matplotlib.pyplot as plt >>> x = np.random.randn(10) >>> y = np.random.randn(9) >>> plt.hist([x, y]) The above code plots two sets of histograms, as expected. My data sets have different lengths, but by coincidence, I had two data sets with the same length. When you call hist on data sets with the same length >>> plt.hist([x[:-1], y]) then hist actually transposes the data; for the above, you get 9 sets of data instead of two. Below is a patch that fixes the issue, but unfortunately, it'll probably break other peoples' code; in fact, it breaks the example code (histogram_demo_extended.py). I'm not sure what's worse: dealing with the inconsistency or breaking a lot of code. But if there's a time to break code, MPL 1.0 might be it :) Best, -Tony Index: lib/matplotlib/axes.py === --- lib/matplotlib/axes.py (revision 8187) +++ lib/matplotlib/axes.py (working copy) @@ -7122,7 +7122,7 @@ try: # make sure a copy is created: don't use asarray -x = np.transpose(np.array(x)) +x = np.array(x) if len(x.shape)==1: x.shape = (1,x.shape[0]) elif len(x.shape)==2 and x.shape[1]http://p.sf.net/sfu/intel-sw-dev ___ Matplotlib-devel mailing list Matplotlib-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-devel
