Uttered "Paul W. Frields" <stickster(a)gmail.com>, spake thus:
There was some list traffic about this several times in the not-too-
distant past... I can't remember the content of all the discussions, but
the idea of whether to use FOP was definitely tossed around. Could
anyone with some time and inclination check the archives and try to
summarize the discussions here? Or is that unnecessary? If someone
were to do that, I would put a page up on the wiki in an agreeable place
(and with an agreeable name) just so we have a reference point.
The concern was that FOP needed some non-GPL assistance to render
some graphic content. Specifically, FOP can render BMP, EPS, GIF,
JPEG and TIFF files without any assistance. With JIMI or JAI (which
are not GPL'ed), PNG can be rendered. With BATIK, also an Apache
product, SVG files can also be rendered.
None of the non-free assistant packages are included or distributed
with FOP. FOP will notice these add-ons if present, but will work
without them, with the only caveat being PNG input will not work.
The official details are at http://xml.apache.org/fop/graphics.html
for those who are interested.
