[gs-devel] JNI Interface to GhostScript

[Russell Lang]

Jim,

RedMon is a Windows printer port monitor.  If you write to 
the printer, it will redirect to stdin of a program which 
can be Ghostscript.  This does involve starting a 
Ghostscript process for each job, but keeps the 
configuration separate from your program.
Note that processing PDF requires random access to the 
file, so you will need to either tell Ghostscript to read 
the file from the local file system, or use one of the 
RedMon tools to write a temporary file then call 
Ghostscript.
