[xep-support] XEP 3.3.1 suddenly crashes

[Alexander Peshkov]

Hello John,

If you need to concatenate several already formatted PDFs you have to
use some third party tools (i.e. those mentioned in the answer of Ken
Holman). However I was talking about another option: with XEP you can
format your documents into our internal XML representation using
appropriate backend (com.renderx.xep.H4XEP). This format have quite a
simple structure and a number of document can be easily concatenated
into a single one. Afterwards this document can be processed with XEP
into PDF or PostScript. Moreover you can automate this process using
XEP API without saving any intermediate result on the disk. This
technic demonstrated in our ConcatFormatter sample available in
Developer and Server editions of XEP (along with API description).

Best regards,
Alexander Peshkov                             mailto:peshkov at renderx.com
