It could get cumbersome to change the Post_Scene_Command
every time you changed scene names. POV-Ray can substitute various values into a command string for you. For example:
Post_Scene_Command=tga2gif -d -m %s
POV-Ray will substitute the %s
with the scene name in the command. The scene name is the Input_File_Name
or +I
setting with any drive, directory and extension removed. For example:
Input_File_Name=c:\povray3\scenes\waycool.pov
is stripped down to the scene name waycool
which results in...
Post_Scene_Command=tga2gif -d -m waycool
In an animation it may be necessary to have the exact output file name with the frame number included. The string %o
will substitute the output file name. Suppose you want to save your output files in a zip archive using the utility program pkzip
. You could do...
Post_Frame_Command=pkzip -m %s %o
After rendering frame 12 of myscene.pov
POV-Ray would shell to the operating system with
pkzip -m myscene mysce012.tga
The -M
switch in pkzip
moves mysce012.tga
to myscene.zip
and removes it from the directory. Note that %o
includes frame numbers only when in an animation loop. During the Pre_Scene_Command
and Post_Scene_Command
there is no frame number so the original, unnumbered Output_File_Name
is used. Any User_Abort_Command
or Fatal_Error_Command
not inside the loop will similarly give an unnumbered %o
substitution.
Here is the complete list of substitutions available for a command string.
|
Output file name with extension and embedded frame number if any |
|
Scene name derived by stripping path and ext from input name |
|
Frame number of this frame |
|
Clock value of this frame |
|
Height of image in pixels |
|
Width of image in pixels |
|
A single % sign. |
