[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.

That sounds really encouraging for freer use. I wonder if we could
host them on Straight Street?

@Mats: Do you have some good SVG conversions of these now to compare
against (e.g from meta fly)?

Hi Steeve,

 

Great you raised the bug in OOo!

 

Here are the sample wmfs together with the Meta Fly conversions.

They mostly look quite good, though with a grid and Meta Fly eval version stamp added.

I'm checking up on the grid with them.

Cheers,

Mats

OK I added them to the bug as more examples.

Mats,

Paste2Xaml libraries have been fixed by Andrej Benedik and he's released a new version now.

I've subsequently updated the conversion util and added some exception handling to it.
We should now be able to see if it's missing components or something else causing it to fail on your machine.
In principle - if Paste2Xaml is working, the conversion util should work also.

Updated files you can find here
   http://www.3point14.com/pub/WMF_to_SVG_0_2_binaries.zip
   http://www.3point14.com/pub/WMF_to_SVG_0_2_sources.zip

Attached are svg files created using the tool - I think you should find the results satisfactory.

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 ;-)

Hi Robert,

 

You (and Andrej?) have done a fantastic job in no time - congratulations!!

Your conversions look close to perfect when I open them in Inkscape. In Firefox I only see the xml code - very compact - lacking meta and presentatin information etc I guess?

 

The only general tweek I would like to do so far - to what I can see in Inkscape - is changing the line style to rounded ends - to make the symbols look nicer and less "edgy".

Funny enough: When I look in the code it looks like stroke-linecap/line-joins areactually are set to "Round"? I don't know enough about svg-xml, but Inkscape does not seem to pick it up.

When I change the line style Line-ends in Inkscape, and save, I get a much larger svg-xml file of course, where the stroke-linecap="Round" setting is duplicated in a "style" entry in the path tag: style="stroke-linecap:round"

 

I also need to check that the fixed hights and vertical positioning of the symbols is retained a bit more, but this looks very good!

How can we best communicate this progress to the OOo, Inscape and Batik projects?

 

Cheers,

Mats

Hi Steve and all,

 

We are working on making Blissymbols available under a free license - but it takes some time.

 

For BCI it is very important that the new licensing will not disturb existing and potential agreements with commercial vendors who want to support blissymbolics in their products. We will need a license that allows packaging of Blissymbolics libraries in proprietary products, while protecting the general freedom of the resources in themselves. Some kind of LGPL-like license I suppose.

 

It will take some time to get this completely solved, but I hope we will have a principle decision soon at least. I will keep you updated as soon as something happens. 

Cheers,

Mats

Mats,

For FF to render those you'd need to add the following attribute to the output .svg file (in the top-most <svg> node:
   xmlns="http://www.w3.org/2000/svg"

You can find an example in the attached.

Indeed FF renders them correctly as rounded and Inkscape appears to be ignoring those attributes.

Now - this should really be done as part of Inkscape's xaml2svg xslt but I can also add this in post-processing stage of the conversion util - I will try and do it sometime this week.

Isn't that always required anyway?

Robert thanks for all you work on this.
If you'd like more test cases's you could try the straight-street.com
Mulberry Symbol set (CC BY-SA) which includes the lemon example I
attached above and for which OOo have now confirmed the bug and
assigned;

For general use you'd need to drop the MS specific namespaces (winfx
and xslt) which aren't used and  I suspect are artifacts of the
conversion transforms.

I have some good news and some bad news

good news is - version of the converter which clears the MS specific namespaces and adds correct xmlns is ready - so we should be fine for winbliss generated files now

bad news is that xaml2svg is not behaving for more complex paths (like the ones found in Mulberry set) - find the attached screenshot and try importing the xaml into Inkscape 0.46 (renders blank for me)

For general use you'd need to drop the MS specific namespaces (winfx
and xslt) which aren't used and  I suspect are artifacts of the

cool, thanks ;-)
Do you know if this works on Mono as I'm on Linux most of the time.

Yea I see nothing but have never imported XAML before, I used file->
import, is that correct?

As I think I mentioned it's not a issue for Mulberry as both formats
are exported from Illustrator so not conversion is needed.

However it would be ideal if it could work with anything you throw at it.
