PStill Use Case: PDF Generation on the command line:

Applies to: ALL VERSIONS 1.90.xx and newer.

Note: PStill needs options! At least the -M defaultxxx options
are recommended. For a list of possible options run 

pstill -H

(or pstill64 -H for the 64 bit version)

This works for any supported source (PDF, EPS, PS. PNG, JPEG, TIFF, etc.).

The simple case:

-v -M defaultall -o output.pdf input

To generate RGB output:

-v -M defaultrgb -M cmykprofile=optionalCMYKProfile.icc -o output.pdf input

Where -M cmykprofile=optionalCMYKProfile.icc is optional, use it for CMYK sources
for exact colors. It should match the source CMYK color space.

To generate matching CMYK output:

-v -M defaultcmyk -M cmykprofile=optionalCMYKProfile.icc -o output.pdf input

Where -M cmykprofile=optionalCMYKProfile.icc is optional, use it for RGB sources
for exact colors. It should match the target CMYK color space. Source RGB color
space is assumed to be sRGB.

Option -v turns on verbose output. You can omit it if you don#t want to see
feedback on what PStill is doing.
