I'm moving all of my dynamic image generation to svg.
Not only does it look better, but it is less resource intensive on my
server allowing me to generate the svg on demand instead of
pre-generating (via cron) twice a month like I had to do with gd dynamic
generation.
However, some browsers *cough*IE*cough* do not support SVG, so I still
need png or gif fallback (I'll decide which after investigating size
difference).
Example SVG to convert -
http://www.shastaherps.org/map/map22.svg
Using convert from ImageMagick in the CLI is fast enough that I may just
use the ImageMagick php module and do the fallback dynamic for the IE
users, but I've run into a bit of a snag - it seems that ImageMagick
doesn't understand xlink.
IE running
convert --size=800x574 map22.svg map22.png
on above file results in a nice pretty map with the county and text, but
the colored hexagons are not displayed.
Is there an easy way around this? IE a php class/function that
understands SVG w/ xlink and can replace the use tags with the polygons
they refer to? If not, I'll have to try to write one, but I'd rather not ...
Thanks for suggestions. It is too bad ImageMagick doesn't understand the
use tag and xlink, that is one of the more useful features of SVG that I
have personally found, makes dynamic generation so much easier.
