Subject RE: Problems with SVG display as background to region-body (FOP-Trunk)
Date Tue, 06 Jul 2010 14:26:26 GMT
I haven't gotten anything but blanks for external-graphic because it
keeps saying it can't find the file.  I haven't researched yet why, if
there's a problem with FOP or just a problem with the format of my link
to the file.  I haven't tested 0.94, only 0.95 and Trunk.

I don't know if there is a log file.  That may depend on how you run it.
I run it in webstart and I set my Java Console to visible in the Control
Panel, so I can see warnings logged there.  You may need to set up
log4j.  That may be able to write it to a file, I haven't tested.

Yes, I misread your message about the 20 meg FO and thought that was the
size of a PDF.  70 megs for one PDF sounds even more insanely large,
though it may be normal depending on the number of pages, images, and
links.  I haven't put any links in mine thus far.  I read someone on the
list thought links were taking up a lot of space.  I don't have an FO
file on mine.  I just pass in an XML file and an XSL file to generate
either a PDF or a printout.  I'm assuming it generated FO code in that
process but it apparently keeps it in memory.  With the way I'm using
the embedded code I wouldn't even know how to get the FO into a file.

There is this in the documentation:
After the Apache FOP 0.94 release, the image handling subsystem has been
rewritten...
The actual image loading framework no longer resides in Apache FOP, but
was instead placed in XML Graphics Commons.

I'm mystified as to why 0.94 has no problem with external-graphic (and
in my case SVGs) and using SVGS as background and the trunk does.

You must of misunderstood me, the FO file is down to 20megs, the PDF
with all SVGs, linking, and such is around 70megs. There are 500+ full
page SVGS and 15000+ links (mainly in indexes). It is a 1400+ page parts
manual. It is quite impressive when done, if I might say so myself. We
run the entire process on a 12gig Ram 64bit Windows XP machine.

Eric, you are exactly right in that I'm also seeing a blank space where
external-graphic should be placing and SVG.

I'll see if I can find the log, or if there isn't one at the moment,
then have it created.

Thanks for your insight and relating your experience with this issue.

I had too many problems with external-graphic, is why I'm using
instream-foreign-object.  When I get time I need to take another look at
getting external-graphic to work.  If you're having the same problem I
was having, everything prints fine except the external-graphic space is
blank, and if you can see the Java Console it will show logs of file not
found.

20 megs sounds ridiculously large for a PDF file.  If you're embedding
images, the problem is no doubt the inclusion of ridiculously large
image files.  The largest reports I've generated so far are around 44kb
for a 1 page report and an 84kb 7 page report which includes this svg
image 3 times per page.. At that ratio a 20 meg file should be over 1600
pages..

Eric,

I'm using external-graphic for all non-background images to keep the
file size down. I have the FO file down to around 20 megs from whopping
250 megs. I also remove all the <xsl:comments /> I place in the output,
this saves another 20 megs. They are used to inform me where the various
attributes and their values are coming from for style debugging.

I'll try and place them inline and see what happens.

If you don't mind can you post one of your SVGs? Just want to see the
root element (don't need the content itself) and any DTD/XSD
declarations. I want to compare what you have and see how mine are
different, if there any differences.

Thanks

My SVG images appear find, using 0.95 and the Trunk, but I haven't tried
background images.  I'm drawing the SVG within instream-foreign-object.

Subject: Problems with SVG display as background to region-body
(FOP-Trunk) I have the following as a child of simple-page-master

<fo:region-body region-name="sectionBody_Section"
background-image="url(file:graphics/partsTable_4ColBG.svg)"
background-repeat="no-repeat" margin-top="{$g_MarginTop}"
margin-bottom="{$g_MarginBottom}" margin-right="{$g_MarginInside}"
margin-left="{$g_MarginOutside}" />

I've tried various values for background-image, from relative to
absolute paths, and other formats for file: (ie. file:///), and with or
without url(). Everything I tried basically worked with 0.94 but once
I'm using the Trunk, no SVG appears in the output as a background or
even as an external-graphic. Note this happens with all the SVGS. Below
is the SVG partsTable_4ColBG.svg. 

Is it a problem with the SVG itself or how I'm referencing the SVG?

<?xml version="1.0" encoding="UTF-8" standalone="no"?> <!DOCTYPE svg

Any help will be appreciated.
