Hey, I'm in the dire need of some simple post processing through POV files.
This is for animations, I could do all of this in - for example - PSP, but
I don't have the patience to go through more than 100 frames. So, having
some kind of limited post processing options availible directly in the POV
file would be really helpful for me at least.

Ultimately, my need boils down to this:

- Change the color of a pixel either before or after anti aliasing.
- Retrieve the color of a pixel either before or after anti aliasing.

And, if there is something that does it:

- Automatically encode all produced bitmaps into an AVI or an MPEG video.
Perhaps even with a sound file?

Does anyone know of one or more patches that do this?

Thanks.

Both things are something not primarily a task for POV-Ray but for
external tools.  There are a lot of programs able to automatically process
a large number of images.  For example:

http://www.imagemagick.org/

Apart from that you seem to have a quite wrong idea on how antialiasing
works, there is no 'before and after' - you should have a look at the
corresponding part of the documentation concerning this.

For combining a number of images to an animation you can find various
tools in the POV-Ray link list:

Do you really need patched POV to do this ?
Just create another scene/animation with the same number of frames and then
start it over previous.

But perhaps no need for second queue ? Perhaps features in screen.inc include
file (locating texturized but semitransparent plane in front of camera) would be
enough ?

No need for it. There is enough of tools to make MPEGs and AVIs so that
programmers can work on real 3D features :-)

I suggest to post questions about patches into povray.unofficial.patches group
in the future.
