Thanks Mr DeWeese

As I am very new to SVG and Batik I didn't fully understand your
explanation.  If you don't mind could you please explain in detail?

Hi Shan,


    Since you seem to know what rasterization is I'm a little at a
loss to know what I should explain in more detail - other than to
point out that the raster version of most geometric primitives is
several orders of magnitude larger - hence the 12K -> 1.8MB change
in size.

Also I can see that opacity operations end up rasterizing.

Not all do - fill-opacity and stroke-opacity are directly transcoded, but group-opacity is rasterized - it is non-trivial to avoid this (if it can be avoided in PDF - I am not a PDF expert).


Thanks Shan

Dear Friends,

I am using Rasterizer in Batik to convert SVG into PDF. It is converting fine but the problem is the size.

12kb svg is converted into nearly 1.8 meg pdf.


Hi Shan,

> Any idea?

    There are quite a number of SVG features that need to be rasterized
for PDF. Like almost all filter effects, also some opacity operations
end up rasterizing (some of these could theoretically be avoided I
think).
