Ok,  I have an animation that was working correctly.  I then changed the
resolution INI file to include this:

[854x391, Animation3]
Width=854
Height=391
Antialias=On
Sampling_Method=1
Antialias_Depth=0
Jitter=Off
Antialias_Threshold=0
Initial_Frame = 1
Final_Frame = 251
Initial_Clock = 0.0
Final_Clock = 1.0
Subset_Start_Frame = 15
Subset_End_Frame = 40

Note, I'm now only wanting to look at a 'subset' of the full animation that
was working correctly.  However when I ran with these new settings things
didn't go as planned.  After writing many parameters to an output file I'm
fairly sure I've found the problem.  Without the subset info in the INI
file, the value of final_frame as used in my POV code is found to be 251.
When
I now add the subset info this value then equates to 40.  Is this correct?

The help file states this in 3.2.1  Language Basics:

final_frame
This identifier reads the value set through the INI file option
Final_Frame=n or the command-line switch +KFFn.

So I was under the impression this value should have been unchanged as a
result of the subset info being added to the INI file.  Is this an error?
Is there a fix for this?  The value I'm after in the code in these cases I
want to be equal to 251 regardless of the subset start and end frames.

I'm using POVray for Windows version 3.6 if that makes a difference.

Thanks in advance,
Carl

I've run into that trouble a long time ago and just wrote a script to get
what I wanted:

http://www.nolights.de/povcode.html#Frames%20of%20an%20Animation

I've suggested then that either the description or the implementation should
be fixed, but as you can see... There was probably too much other stuff
going on, after all, POV-Ray is freeware maintained by geniusses, and
they're very much asked for outside of their spare time. :-)

Thanks.  That code should get me back in business.  If it makes a difference
I'll second your call that the implementation should be fixed.
