This may be slightly off-topic, but the task you describe here is
easily done with ImageMagick.
You can type "convert filename.svg filename.png".
If you want to convert a bunch of files:
for f in ~/pictures_svf/*.svg; do
f1=`basename $f .svg`
convert -resize 16x16 $f $f1.png
The other salient point is that SVG is a vector graphics format, while
PNG is a bitmap format, so you'll lose quite a bit of quality if
someone zooms in.
Hey that's great Alex! And to get us back on the topic, wouldn't it be
great to have a posting of how to do this for OpenOffice that a school
using FOSS could easily implement, something like:
1. Download Open ClipArt package:
But we have to figure out which package to download, and whether to use
SVG only package, or package with PNGs (possible duplicate file name,
2. Download ImageMagick:
3. Run the following script:
(But we'd want to save the files to a new location, possibly on the
school's file server so all LTSP servers could easily get to the clip
art. That would also solve the potential duplicate file name problem).
4. Is there anyway to set the location OpenOffice Impress looks in
first when you want to insert graphics?
While a school's IT person would have to do the above steps, it would
then be in a user friendly manner for teachers to use it. I agree 100%
that vector graphics are much more efficient (I bet the whole Open
ClipArt package will be hundreds of MB if not GB when converted to
bitmap, but if it's located on a school's server, it shouldn't be too
bad) but until OpenOffice supports SVG, it would really be great for
teachers to have easy access to a rich set of clip art to use both for
their own documents, and for students to use for projects like the one
Sharon described and mine.
Final question: ImageMagick's license claims to be compatible with GPL,
but is not GPL, is that an issue?
