[matplotlib-devel] bug introduced in 0.87.3: subprocess error while saving eps
Sorry to bother you again, but I recently upgraded from 0.87.2 to 0.87.3, and cannot save eps files anymore. I get a 'subprocess' error.I am running Python 2.3, mpl 0.87.3, and TkAgg (although that shouldn't matter).
Error occurs whether using toolbar or savefig to save.Here's the script and the errror. Has this been fixed in svn?>>> from pylab import *>>> plot([1,2,3])[]>>> savefig('c:/temp/test.eps')Traceback (most recent call last): File "", line 1, in ? savefig('c:/temp/test.eps') File "C:\Python23\Lib\site-packages\matplotlib\pylab.py", line 811, in savefig

Using Tomcat but need to do more? Need to support web services, security?

Just as a note, if you have Cairo, you have PS, PDF, SVG, raster, and, indeed, native draw-to-the-screen functionality. They're not all robust and complete, but it's seeing a lot of development. A robust, numpy-aware PyCairo would be really nice. In short, Cairo has essentially the same goals (plus a few more) as Kiva, except it's written in C. There's some discussion of using it in wxWidgets, and, of course, it's already used in newer GTKs. -Chris -- Christopher Barker, Ph.D. Oceanographer NOAA/OR&R/HAZMAT (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception [EMAIL PROTECTED] - Using Tomcat but need to do more?

Last I checked if I recall correctly, about a year ago, the PS backend merely dumped a raster image and didn't do real vector graphics. Has this changed? JDH - Using Tomcat but need to do more?
