Hallo!

i wrote a class to write Openoffice ODG File from a Canvas, various
operation are supported see Manual.txt in the archive

http://www.alb42.de <- ODG Writer Class for FPC

Features:

    * Basic Operation of TCanvas are supported (Line, Rectangle,
FillRect, Ellipse, Arc, Chord, RadialPie, Textout, StretchDraw, Draw,
Pixels)
    * Various styles (line width/line colors/dash/fill colors/Fonts
type/font size) are supported.
    * Draw/Stretchdraw copied as pictures to the odg file.
    * Items can be grouped. (means this items are grouped in
Openoffice)
    * simple example is included

currently it only supports writing, as long as my project (Apace see
website) only need a write support.
But i think its interresting for more people out there, so i announce
it here.
I'm very interresting about Feedback.

Ciao

P.S. anyone knows why the ZIP files (with the zip unit) are not
compressed? only packed together? or why the TZipFile class produce
not-openable ZIPs (not openable in Winzip/Winar/7Zip and as ODG in
Openoffice)?

ODG is actually a vectorial graphics format and Free Pascal now has an
official vectorial graphics library, FPVectorial (available in svn
Free Pascal), you could also write an export module for this library
(if you are interrested we can then talk more by e-mail):

http://wiki.lazarus.freepascal.org/fpvectorial

The advantage is that this library supports multiple inputs and
outputs, so by writing an export module for it you can also convert
from any of the currently supported vectorial formats (currently reads
PDF and G-Code). At the moment it supports lines and bezier curves in
paths, which is enough for any drawing, but we could also add
generation of circles and texts to make it easier to generate images
from code.
