Wich parsers to use

[Esteban Gonzalez <eg...@outside.com.ar>]

Hi!
I´m using XML --> XSL --> FO --> PDF transformations...

and i´m willing to know wich is the best parser to use for performance.
Unfortunately I DO have to create a DOM tree of the xml and modify it with
some data from a database... i´m using xerces to do so... but i´m not sure
that´s the best way to go...

any ideas or insights?

Best Regards,

If you really talking about parser, it's actually doesn't matter at all, 
because in this processing schema parsing itself is I believe about 1% 
performance consumer.

If you care about performance, try keep SAX at transformation and 
optimize you formatting (see the list achiv? about it).
But first you have to profile you application and spot bottlenecks and 
only then try to optimize concrete modules.

Chances are you don't have to. You can fire SAX events
from your database directly into the XSLT processor, and
use document() for aggregation with you static XML. There
are other possibilities for aggregation if you are using
Cocoon or a standalone xinclude processor.

You can use height and/or width, in a length unit (cm, mm, pt).
If you use only one of these properties, the aspect ratio of
the image will be preserved.

Image resolution in FOP

["Philip S. Constantinou" <ph...@wayfinder.net>]

I'm struggling a bit with embedding images into FOP.

The FOP to PDF converted always seems to output the image at 72 DPI
regardless of the stored format. So far I've only tried GIF which doesn't
support resolution and JPG which does but in both cases the image comes at
72 DPI.
Any other options- attributes to the external-graphic tag? other file
formats?

Thanks -
