Powerpoint to SVG conversion[edit]

I am helping to prepare an upload a set of 265 life cycle diagram, available in Powerpoint, containing fungal life cycle diagrams in English and Spanish. The originals are in Powerpoint ppt format and a mixture of embedded bitmaps, connecting arrows and editable text. I can produce high-res png version, but svg versions would be translatable into further languages. I cannot do this, googling did not give me any insights either. No Adobe illustrate available, Inkscape available but not time to redo 265 diagrams manually. Anyone has an existing (semi-) automatic workflow for this and is willing to support a conversion? --G.Hagedorn (talk) 04:21, 2 January 2012 (UTC)

I think not, something like that I've never seen. (I have not done it yet, manually you can do it (using PDFCreator), convert to PDF, and then in SVG. -- πϵρήλιο 14:35, 9 January 2012 (UTC)

(Wikimedia?) Rendering issues on SVG files[edit]

Hello all, I'm having some rendering issues with several Georgian keyboard layouts I created. The first was based on They all appear fine on Inkscape and on my browser, but when Wikimedia renders them, it adds a bunch of stuff, specifically:

  • A black bar by the pipe key.
  • A black square in bottom left corner
  • A big honking lowercase "h" over the middle.

I should note that I created the latter three from the first one, which was fine in itself, until I tried to correct some minor issues in a new version.

Hello Quintucket, do you know Help:SVG#Fonts!? -- πϵρήλιο 18:45, 4 January 2012 (UTC)
Yes! Thank you! :•) One of the files was a slightly different issue, but fixing the other ones gave me the confidence to solve that one as well. --Quintucket (talk) 20:08, 4 January 2012 (UTC)

Problem with Libremap files[edit]

I'd like to create a town-level map of New England, based on the files available at Libremap. However only Connecticut and Rhode Island will display properly in Inkscape. The other four states Maine, Massachusetts, New Hampshire, and Vermont show up simply as the document background, with no objects visible, and no objects editable when I select all. Any ideas what's wrong? Thanks, --Quintucket (talk) 17:24, 10 January 2012 (UTC)

For me the problem is on all maps the same, the stroke-width ist 0.000000 !? Correct would be about 0.01px. -- πϵρήλιο 00:30, 14 January 2012 (UTC)
I found the same problem as Perhelion above. So the solution is to simply select all, then in the "fill and stroke" panel choose a stroke paint, and under the stroke style choose a width of 0.01 px. -- Orionisttalk 07:21, 14 January 2012 (UTC)
Aha! Thanks guys. :•) --Quintucket (talk) 07:52, 14 January 2012 (UTC)

Black blob[edit]

Metropolitian Railway 1863.svg

Just started with inkscape and edited File:Hammersmith & City Line.svg to create this image of the railway when it first opened. However I have a black area which I can't see in inkscape! Edgepedia (talk) 17:53, 13 January 2012 (UTC)

Uploaded png file without artifact for now.

✓ Done fixed, flow elements deleted. -- πϵρήλιο 00:15, 14 January 2012 (UTC)
Metropolitan Railway (1870).svg
Thanks! However got the same problems with this file. What am I doing wrong? Edgepedia (talk) 13:00, 14 January 2012 (UTC)
See here. I had the same problem. Inkscape is just annoying. I see someone else fixed it for you, but try to fix it anyways and upload the new version. See if you can find any elements named <svg flowRoot ...> and remove them. You'll need to go into the XML editor in the edit menu, and likely expand your elements. You can also open it in a proper text editor (don't use TextEdit or Notepad) and search for it. Regards, --Quintucket (talk) 15:21, 14 January 2012 (UTC)
Thanks, I'll copy this to my talk page for next time. Edgepedia (talk) 20:15, 15 January 2012 (UTC)

Gnuplot problem: Wrong label values on the Y-axis[edit]

Bielefeld population
Eberswalde population

The labels on the Y-axis of these two Gnuplot diagrams end with 2024, but obviously should end with 2025. While I could correct the issue in the SVG output directly, I'd prefer to understand and fix the underlying problem. Any ideas? --Tkarcher (talk) 19:28, 26 January 2012 (UTC)

I think that's really an idiosyncrasy with the generating program "GNUPLOT 4.4 patchlevel 4" which only people who know about Gnuplot might help you with... AnonMoos (talk) 01:31, 27 January 2012 (UTC)
Thanks for the good advice to ask gnuplot experts: A guy in this gnuplot usenet group noticed I used wrong values for the xtics variable (based on the wrong assumption that a year has 365 days - the correct value is 365.2425). It's fixed now. :-) --Tkarcher (talk) 16:04, 27 January 2012 (UTC)
