Hello Benoit,
Where is your copy of XEP installed? Is it under 'subst'ed directory
also? Could you try to run your test with temporary directory pointing
to some directory on disk C (i.e. C:\TEMP)? You can set it by
specifying appropriate XEP option on Java command line:
-Dcom.renderx.xep.TMPDIR=C:\TEMP
I think testing on Linux box could also be helpful.
Best regards,
Alexander Peshkov mailto:peshkov@renderx.com

MB> Hi Alexander,
MB> I don't do anything special regarding temp directory. Should I? I use the default xep.xml.
MB> All URIs are local; fo, at, pdf and images are local. Images are given by a relative path. Example:
MB> <fo:external-graphic scaling="uniform" height="295mm" content-height="152.4mm" content-width="101.6mm" src="url(../graphics/ENR-6-BirdMigration.svg)"/>
MB> Which gives in AT:
MB> <xep:image system-id="file:/H:/eAIP/_dev/eAIP/eAIP-pack/graphics/ENR-6-BirdMigration.svg" id="image6" type="image/svg+xml" x-from="0" y-from="4491" scale-x="0.5966168839595076"
MB> scale-y="0.5966168839595076" width="288000" height="356167">
MB> [127kB of encoded binary]</xep:image>
MB> My H: drive is a "subst" to a local C: directory.
MB> Some images are rescaled, and I didn't check if this issue is related to rescaling. Does rescaling happen in FO->AT or in AT->PDF? or in the PDF browser?
MB> I am running XEP on Win NT. A colleague of mine has the same problem on Win2k. I could test on a Linux box is that can help.
MB> Cheers,
MB> Benoit
