[Mats Lundälv]

Hi Robert,
Thanks for your efforts!

I have now tested opening my wmf files with the Paste2Xaml tool - and unfortunately it does not handle any of the circles, semi-circle or circle segment components of the wmf:s - just like SVGFactory they just disappear. Only straight lines are displayed. I didn't manage to run your app, probably because I don't have the latest .net components installed - or is it a command line tool? Anyway it should not work any better than the Paste2Xaml routines that it uses, I suppose?

The application that actually let's me both open the wmf:s correctly and save them as reasonably usable svg images now is OOo Draw. The problem there is that the line widths are set to zero, and that the black line colour is set to undefined. I can open these converted svg images in Inkscape and manually correct them to a good result - but it would be a HUGE work for the between 3000-4000 thousand files I'm working with - close to undoable.

ImageMagick can also open and display the wmf:s correctly, but cannot convert to correct svg.

The most promising auto-conversion tool so far is probably the wmf2svg-0.8.1.jar tool. It actually picks up all components of the wmf, and the converted svg:s are basically nicely displayed in both Firefox and Inkscape - except it cannot handle the circular elements correctly:
Circles are correctly positioned but double diameter in size
Semi-circles are collapsed to a blob - a very small filled semi-circle - incorrectly positioned
Circle segments are displayed in a weird way - double diameter - incorrect position, orientation (ignored mirroring/flipping) and rotation (45 degrees).

So what are the alternatives:
- Find a way to use the components that OOorg uses and try to get them improved
or/and
- Approach the developer of wmf2svg-0.8.1 and try to persuade him to take a look at my odd line drawing wmf files and try to handle the circular shapes better
- others?

 

I attach a few samples of the Blissymbol wmf files I'm struggling with, if any of you want to see for yourselves what happens ;-)

Cheers,

Mats

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

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

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.

That's exactly what the unoconvert utility does that I tried above. My
results seem to be that I also lost the border line.

As these are the best I think it would be worth your while contacting
both projects with samples and asking for a fix. I'll try to find the
right person to contact at OOo

Thanks Jonathan!

I have just downloaded the trial version of the Meta Fly conversion tool.

It does the conversions very well indeed. The "difficult" examples (with the different kinds of circle line objects come out beautifully in almost all cases I've tried so far. So the performance of the this tool is really a good target for any open source competitors.

This could actually do the conversion in a manner that would require very little manual tweeking - while waiting for the real solution: A tool that creates the symbols directly in SVG. I am working for that. We use an application called WinBliss to produce the symbol files in a number of formats, including WMF. So the natural solution is to add SVG to the list of supported formats there. It's only a matter of time and resources for the software developers.

I'll probably try to convince one of my employers here to invest in Meta Fly to quickly produce a good SVG library for general access - as soon as that's ok with BCI (Blissymbolics Communications International) - soon I hope.

Hi Robert,
Thanks for your efforts!

I have now tested opening my wmf files with the Paste2Xaml tool - and unfortunately it does not handle any of the circles, semi-circle or circle segment components of the wmf:s - just like SVGFactory they just disappear. Only straight lines are displayed. I didn't manage to run your app, probably because I don't have the latest .net components installed - or is it a command line tool? Anyway it should not work any better than the Paste2Xaml routines that it uses, I suppose?

The application that actually let's me both open the wmf:s correctly and save them as reasonably usable svg images now is OOo Draw. The problem there is that the line widths are set to zero, and that the black line colour is set to undefined. I can open these converted svg images in Inkscape and manually correct them to a good result - but it would be a HUGE work for the between 3000-4000 thousand files I'm working with - close to undoable.

ImageMagick can also open and display the wmf:s correctly, but cannot convert to correct svg.

The most promising auto-conversion tool so far is probably the wmf2svg-0.8.1.jar tool. It actually picks up all components of the wmf, and the converted svg:s are basically nicely displayed in both Firefox and Inkscape - except it cannot handle the circular elements correctly:
Circles are correctly positioned but double diameter in size
Semi-circles are collapsed to a blob - a very small filled semi-circle - incorrectly positioned
Circle segments are displayed in a weird way - double diameter - incorrect position, orientation (ignored mirroring/flipping) and rotation (45 degrees).

So what are the alternatives:
- Find a way to use the components that OOorg uses and try to get them improved
or/and
- Approach the developer of wmf2svg-0.8.1 and try to persuade him to take a look at my odd line drawing wmf files and try to handle the circular shapes better
- others?

 

I attach a few samples of the Blissymbol wmf files I'm struggling with, if any of you want to see for yourselves what happens ;-)

Cheers,

Mats

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.

Mats,

Did you take the time to look at the weather icons I pointed you to?

http://www.openicon.org/icon-ark/weather-icons.svgz

18 icons in 2Kb.

Can I ask you once again to consider and understand the reasons for publishing bliss symbols together in batches as <symbols> in svg files rather than individually.

regards

Thanks Jonathan!

I have just downloaded the trial version of the Meta Fly conversion tool.

It does the conversions very well indeed. The "difficult" examples (with the different kinds of circle line objects come out beautifully in almost all cases I've tried so far. So the performance of the this tool is really a good target for any open source competitors.

This could actually do the conversion in a manner that would require very little manual tweeking - while waiting for the real solution: A tool that creates the symbols directly in SVG. I am working for that. We use an application called WinBliss to produce the symbol files in a number of formats, including WMF. So the natural solution is to add SVG to the list of supported formats there. It's only a matter of time and resources for the software developers.

I'll probably try to convince one of my employers here to invest in Meta Fly to quickly produce a good SVG library for general access - as soon as that's ok with BCI (Blissymbolics Communications International) - soon I hope.
