Batik-rasterizer/SVG for image creation via script?

[Thomas Singer <th...@regnis.de>]

Hi all,

I want to simplify the generation of application images. Typically those 
application images contain common parts (e.g. a user-symbol) to make it 
easier for the application user to recognize related tasks. If such a 
common part changes (e.g. I want to modify the used user-symbol), 
currently all application images need to be updated. If one needs to do 
this by hand, it's no fun. Now my question:

Is it possible to (ab)use SVG and Batik's rasterizer to render 
application images from existing raster-images (common parts)? Is it 
possible to create (semi)transparent png files with the rasterizer?

Thanks in advance!

Tom

     Yes, take a look at the SVG 'image' element.  It can reference
raster content (JPEG and PNG is required).

     Yes, this is the default for PNG.  It does not normally
generate pallete PNG (and if you tell it to it doesn't generate
alpha - this makes palletization really hard...).
