Python.exe hangs on creating .wmf files

[ProfessorF]

Running WindowsXP Pro 64-bit. Opened a .wmf file created in diaw.exe, modified it with Inkscape 0.47, and tried to save it as a .wmf file. A blank Python.exe command box appears and hangs. I have to close it manually. The resulting .wmf file has 0 bytes.

similar to bug #480664 “Save copy as ... pdf -> no file created”:

[su_v (suv-lp)]

Could you attach the original WMF file so we can try to reproduce this issue?

[ProfessorF (spam-fellmeth)]

Here it is as a SVG file. This file saves as a PDF just fine. It's only saving as a WMF that causes Python to hang.

Confirmed on Windows XP, Inkscape 0.46, 0.47 and bzr rev. 9275. Blank python command box.
Also confirmed on Ubuntu 9.10, Inkscape 0.47 and bzr rev. 9288, Uniconvertor 1.1.4, but I also get an error message (and of course no command box...).
Exporting simple shapes (rectangles and ellipses) works well on both operating systems with all Inkscape versions.

To reproduce, it is sufficcient to paint some Text (in Arial Narrow, which it offers on my system) on a blank page and try to save that to WMF. My inkscape.exe's version resource: 0.47.0.0 (from the download Inkscape-0.47-3.exe), python25.dll is 2.5.1150.1013.

This is a font name resolution problem!

My Analysis:
- Get the cmd process' command line, open cmd, cd to inkscape's python directory, launch the copied command line -> "...python25.dll not found..."
- Install Python 2.5.4.msi, default options, restart inkscape, retry - no dice
- copy inkscape's dll to the python folder and retry manual cmd step
Messages:
I can't find font Arial Narrow. I'll use Slim instead
I can't find font Slim. I'll use Slim instead
(...)
ValueError: Cannot find font Slim.

So, python is unable to find a font listed in Windows' control panel? Maybe because it didn't add the localized "standard/bold/italic" like Windows did?

- Use Calibri instead. Calibri is present in Win's font list both undecorated and decorated. No change.
- Use Algerian instead, Algerian comes with no bold and/or italic varaints. No change.
- Try Text-to-Curves. What, Inkscape doesn't have this feature?

I'm out of options. No idea where the font substitution tables are under a current windows.

> Try Text-to-Curves. What, Inkscape doesn't have this feature?

1. Select text
2. menu 'Path > Objects to Path' (Shift+Ctrl+C)
3. If needed, ungroup (Shift+Ctrl+G) and combine (Ctrl+K) the resulting selection.

running Windows XP, and Inkscape 0.48.0 r9654 (Aug 16 2010), when I save the file IPSchematic as .wmf I do not get a hangup. This version of Inkscape is using Uniconvertor 1.1.5

Instead I get the message below: I get this message any time I save an object that has a radial gradient fill.

[Alvin Penner (apenner)]

if I remove the radial gradients then I get the following wmf file:

[Alvin Penner (apenner)]

fwiw, the text problem appears to have been resolved. The attached file has text as text, and can be converted to wmf.

[Alvin Penner (apenner)]

the result is attached: This conversion did not work previously, using uniconvertor 1.1.4

[Kevin Davies (daviesk24)]

I got the same errors as JazzyNico posted on 2010-04-03 when I opened the testtext.svg image in Inkscape and tried to save a copy as .wmf. I'm running Inkscape 0.47 on Ubuntu 10.04. I've read some of the other threads too and I can't find a solution. I've checked for clipboard managers on my system (there are none), and I've reinstalled both Inkscape and the python-uniconvertor package (I have version 1.1.4-1build1 of that package). I also tried to upgrade to Inkscape 0.48 but I wasn't able to get it to compile correctly.

Is there a solution? Thanks!

You need UniConvertor 1.1.5 for exporting text objects to WMF.

[Beluga (buovjaga)]

No hang for me with IPSchematic.svg. Plz re-test.

Win 7 64-bit
Inkscape 0.92pre1_64bit r15044

[jazzynico (jazzynico)]

The WMF output filter was rewritten in 0.91 (without uniconvertor) and no longer hangs or fails to save.
