[sage-support] Re: Don't know a PDF representation for alpha in graphics?
I have uploaded a patch to the trac, ticket 13732, which fixes this for all the plot commands that seem to accept alpha. (To find them, I performed a grep alpha sage/plot/*py and looked at those files.) The doctests in sage/plot pass for me, though I had to make some changes to older doctests because float gives a different output; I haven't yet tried doctesting anything outside of that directory. I couldn't find anything that made the save command choke like this except the alpha option, though I didn't try very hard. I hope someone reviews it; it should be easy, unless I did something stupid. john perry -- You received this message because you are subscribed to the Google Groups sage-support group.

With this change, I can sage PDF with alpha, and it probably fixes a lot of other thing Huh. See http://trac.sagemath.org/sage_trac/ticket/14074 for an example where alpha works fine with saving as a pdf. Of course, you could always put the alpha to float(.5) or something... s, as well. -- You received this message because you are subscribed to the Google Groups sage-support group.

If possible, matplotlib should rely on duck-typing: try: alpha = float(obj) except ValueError: here we know that obj is not a float If not, the solution is probably to patch sage's commands that create graphics, to change RealLiteral's to float's. That should be fixed as well. Sage shouldn't feed its own floating point classes to 3rd-party libraries, they certainly aren't doctested with extended precision floating point numbers. -- You received this message because you are subscribed to the Google Groups sage-support group.

Hello Finally got round to it. On Thursday, November 15, 2012 11:44:36 AM UTC-6, Volker Braun wrote: I think I saw that before. Maybe converting coordinates to RDF works? Please open a ticket if you can isolate a test case. RDF doesn't work, either. float does. I'm trying to write up a patch now. The alpha option should in fact be float, and not RFE or RDF, should it? I was thinking of making the change there, when the option is set, though I could also convert RDF etc. to float in the backend. john perry -- You received this message because you are subscribed to the Google Groups sage-support group.

Okay, does anyone know how I change files in the library in such a way that mercurial actually notices? I can modify the matplotlib backend for PDF's so that this works, but those files don't show up in the source directory, so hg doesn't pick up on the changes. How do I supply a patch for this circumstance? -- You received this message because you are subscribed to the Google Groups sage-support group.

Or even better, in my opinion, post the patch to the matplotlib mailing list, or make the change in the matplotlib github source and submit a pull request to them.
