[xep-support] JRE change produces different result (?)

[Mark Cilia Vincenti]

Hi,

I was clearing my hard disk space and to save space I uninstalled JRE 1.5,
since I already had the latest version of Sun's Java.
Then I noticed that XEP wasn't working, so I edited my xep.bat and changed:

C:\Program Files\Java\jre1.5.0_06\bin\java

to:

C:\Program Files\Java\jre6\bin\java


XEP is now working again, but I've compared the same PDF output from the
older JRE with the output of the newer JRE and, despite not having any
visible differences (at least I'm not spotting anything!), the file size is
different. The older JRE produced a 534KB file whereas the newer JRE
produces a 476KB even though they are using the same FO and XML.

Since file size is not critical, because these files will be sent to
printers for printing, I am wondering if I should re-install JRE 1.5 or not.

Does anyone know what kind of differences there would be, and whether I
should keep on using JRE6 or revert back to JRE 1.5 to have the best
quality?


PS: As a guideline, the FO uses TIFF images and SVG graphics, all in CMYK.
