22.214.171.124 Automated execution
POV-Ray for Unix is well suited for automated execution, for example, for rendering diagrams displaying statistical
data on a regular basis or similar things.
POV-Ray can also write its image output directly to stdout. Therefore the image data can be piped in another
program for further processing. To do this the special output filename '-' needs to be specified. For instance:
povray -iscene.pov +fp -o- | cjpeg > scene.jpg
will pass the image data to the
cjpeg utility which writes the image in the JPEG format.
The text output of POV-Ray is always written to stderr, it can be redirected to a file with (using a
povray [Options] 2> log.txt
See also Directing Text Streams to Files.
For remote execution of POV-Ray, as for example in a rendering service on the web, make sure you read and comply
with the POV-Ray Legal Document.
