Description Alexandre Prokoudine 2008-09-02 06:57:08 UTC
Currently PS/EPS surface flattens transparency to a bitmap. This can make a resulted file much larger than it could be. A good solution would be to flatten transparency in overlapping regions to new paths that have opaque fill matching the transparency projection.
