Ang: Re: Ang: Re: Ang: Re: Ang: Re: wmf to svg conversion

[Mats Lundälv]

Yes Steeve, you may say that ;-/

Now I have tried Robert's suggestion - the wmf2svg tool, and guess what?

I get proper conversions to valid svg files with all graphical elements included, including the circular elements, it seems - BUT these circular elements are not proportionally sized - see the example image dumps below. So here I am, still stuck.

The problem is of course that we are messing with a complex and poorly documented proprietary Microsoft format - that Microsoft themselves cannot handle consistently between different Office versions. Since Office 2003 circle segments are not displayed as they were before. (Microsoft support suggested us to use png:s instead of wmf - stndard bitmap format instead of a Microsoft non-standard vector format, ha!) Different programs obviously output and display wmf:s slightly differently and few have any real clue to the details of the format, I suppose.

So no wonder really that our conversion tools have problems in converting consistently.

I'll ponder on this now for a while.
Thanks again for your help!

Cheers,
Mats

hmm looks rather like inkscape uses wmf2svg, or at least makes the
same assumption about wmf.

So I guess it's the same a Garry finds with export to wmf, you need to
hand adjust the images to compensate for wmfs badness :-(

If you send me the source wmf in question I'll have a quick look but I
can't promise anything right now as I'm swamped.

Is there any chance you could go back to the original source of the
wmfs and get SVGs ? Or do you have a library of WMFs.

We really need SVG to be adopted by everyone ASAP. Take up has been so
slow for some reason. It seems we've been rather 'sold down the river'
with wmfs :-(

> Microsoft support suggested us to use png:s instead of wmf - stndard bitmap format instead of a Microsoft non-standard vector format, ha!

Bah, that shows real ignorance of the issues; why not recommend SVG as
a better vector format?

Matt,

could you try if paste2xaml is rendering your files correctly
http://www.wpf-graphics.com/Paste2Xaml.aspx

the tool is not perfect yet but the author, Andrej Benedik has fixed a few issues for me last year for .emf(s) - so he may be willing to rectify the Ab2d.ReaderWmf library further

now, the latest Inkscape is capable of importing vector graphics from xaml
    http://wiki.inkscape.org/wiki/index.php/ReleaseNotes046#XAML_import.2Fexport
I've tried it and it gave promising results

if that route works, then
- writing a utility to convert wmf->xaml using Ab2d.ReaderWmf is not a problem

- Inkscape's xaml import is a set of xsl transformations (inkscape-0.46\share\extensions

\xaml2svg\) - some investigation will be required as to which order to apply them in / how to assemble the output but all in all it looks feasible

r.

OK, I've glued a little application together employing the components outlined below (going through xaml as an intermediate step)

http://www.3point14.com/pub/WMF_to_SVG_binaries.zip
http://www.3point14.com/pub/WMF_to_SVG_sources.zip

binaries require the Microsoft .NET Framework 3.5 installed
sources can be built using Visual C# 2008 Express

Matt,

could you try if paste2xaml is rendering your files correctly
http://www.wpf-graphics.com/Paste2Xaml.aspx

the tool is not perfect yet but the author, Andrej Benedik has fixed a few issues for me last year for .emf(s) - so he may be willing to rectify the Ab2d.ReaderWmf library further

now, the latest Inkscape is capable of importing vector graphics from xaml
    http://wiki.inkscape.org/wiki/index.php/ReleaseNotes046#XAML_import.2Fexport
I've tried it and it gave promising results

if that route works, then
- writing a utility to convert wmf->xaml using Ab2d.ReaderWmf is not a problem

- Inkscape's xaml import is a set of xsl transformations (inkscape-0.46\share\extensions

\xaml2svg\) - some investigation will be required as to which order to apply them in / how to assemble the output but all in all it looks feasible

Yes Steeve, you may say that ;-/

Now I have tried Robert's suggestion - the wmf2svg tool, and guess what?

I get proper conversions to valid svg files with all graphical elements included, including the circular elements, it seems - BUT these circular elements are not proportionally sized - see the example image dumps below. So here I am, still stuck.

The problem is of course that we are messing with a complex and poorly documented proprietary Microsoft format - that Microsoft themselves cannot handle consistently between different Office versions. Since Office 2003 circle segments are not displayed as they were before. (Microsoft support suggested us to use png:s instead of wmf - stndard bitmap format instead of a Microsoft non-standard vector format, ha!) Different programs obviously output and display wmf:s slightly differently and few have any real clue to the details of the format, I suppose.

So no wonder really that our conversion tools have problems in converting consistently.

I'll ponder on this now for a while.
Thanks again for your help!

Cheers,
Mats

surely there must be are better tools? Oh well.

Looks like image magick has not improved since 2002 and Robert's
solution was tha good one even back then
http://studio.imagemagick.org/pipermail/magick-users/2002-August/004112.html

Garry et al edit the files in Adobe Illustrator and export to wmf and
SVG. The wmf files need quite a bit of hand correction, probably due
to the very privative facilities of that format. The SVGs need very
little attention.
