Hi,
Don Demcsak (who rebranded himself to Don XML) has
started the SVG2XAML open-source project that -
surprise, surprise - converts the open royality-free
SVG format to Microsoft's upcoming all-in-one
Windows-only XAML format.
Somehow Don XML misses the point. Shouldn't it be
the other way round?
Anyway, Don XML introduces himself on his blog story
"I'm Not Don Box, but I wish I Were":
No I'm not Don Box. I'm Don Demcsak, but DonXML has
been my nickname since about 1999, since my days on
VBXML and svg-developers discussion groups, so I
decided to keep the handle. It was given to me by my
coworkers and while most folks still associated Don
Box with COM. In the world of Google you need an
identity that people can spell, and most folks
(Westerners) can't pronounce or spell my last name
correctly on a consisitent basis.
I've been an evangelist for XML and SVG since 1999
and .Net since 2001, but my day job is an indie .Net
consultant out of New Jersey. I was the TE on Kurt
Cagle's SVG Programming book out on APress. I am also
the PM for the SharpVectorGraphics open source project
bringing a native SVG rendering engine to .Net.
To get back to SVG2XAML Don XML writes in his blog:
I created a new GDN [Got Dot Net] Workspace for this
version of the code, and called it Svg2Xaml. It is
really just SharpVectors on Longhorn, but I think
people will find it easier with that name. I put all
the source into version control, and created two
releases, one of just the binaries, and another a zip
file with all the source. Any and all changes will be
made to the SharpVectorGraphics codebase, and migrated
to this project. SharpVectors is by no means
complete, but will render most SVG. If you want to
join the fun, the team is always looking for help.
Now onto the fun stuff. I used the standard tiger
SVG example as a base SVG example (the URL can also be
found in the SharpViewer’s combo box), and had the
viewer render it (here’s a raster version for those
with an SVG viewer). I then setup up my default
printer to the Windows Client Printer Driver. I
haven’t figured out how to change the printer
properties thru code, so you are going to also have to
go to the Advanced tab of the Printer Properties,
click the Printing Defaults. On the General tab,
change the Output Format to Windows Client Markup File
and click OK. If you don’t do this, you will get the
container version, which is used in the Digital Rights
Management support (not the open XAML format). Then
just click, File|Print and the Printing window will be
displayed and then the SaveAs dialog box is displayed.
The save as type should be set to xaml at this point.
If it says container, then you didn’t set the Output
format of the Print Driver to XAML. Save the file,
and voila, you have XAML.
So the net process is conversion of SVG to a GDI
Graphics object (via the SharpVectors GDI Rendering
engine. The graphics object is sent to the printer,
and the WCPD reverse engineers the graphics object to
XAML. You are not going to get any reuse of graphic
objects with this model. If a path is 20 different
places, it will show up 20 different times in the
XAML. You will have to convert the path to a component
and reuse as needed, but at least you don’t have to
convert all the paths yourself.
So, if you are a graphic artist, and want to start
creating some stuff with XAML (aka Avalon Elements)
you can use Adobe Illustrator (version 10 or CS) and
save to the SVG format. Then you can convert the SVG
to XAML using Svg2Xaml (aka SharpVectors on Longhorn).
Not the way you will be doing it in the future, but it
will work for now.
