postproc.cpp is NOT a programm but a C++ source file.

To do what you want, you need to get the source files, edit the line 
360, and compile the executable.

You'll obviously need to get a C++ compiler with all the needed libraries.

You need the sources of megapov 1.2.1 (
> http://megapov.inetart.net/packages/unix/megapov-1.2.1.tar.bz2

)

Then the file is ./source/patches/postproc.cpp

Once changed, you "just" have to compile your version of megapov.

Well, sorry but I have no windows system to generate such binary.
Maybe someone else can help ?

Anyway,I am very grateful to you.I have solved this problem.However,I
encountered a new problem.I need to generate ancillary image planes with
MegaPov.Such as:




I found that the output rendered by MegaPov is the same as POV,that means no
difference with POV. How can I make MegaPov output auxiliary images such as
above I listed? Beg a hot!Thanks and expecting reply! Best wishes!

It seems to be in the doc:

http://megapov.inetart.net/manual-1.2.1/megapov0121.html#post_processing

Read it carefully and slowly. (hint: global_settings)
