fieldcomb - combine two or more field frames for video animation
fieldcomb [ -e|-o ][ -r ] [ -f combined.hdr ] field0.hdr field1.hdr ..
Fieldcomb combines two or more field frames into half as many final
video frames for field-based animations. Normally, the even scanlines
in the output are given over to the first, third, fifth, etc. pictures
given on the input, and the odd scanlines are given over to the second,
fourth, sixth, etc. pictures on the input. This behavior corresponds
to the -e option, which is set by default. To reverse this ordering,
the -o option must be specified.
Normally, fieldcomb will name output frames by dividing the numbers on
the input field file names by 2, inserting a ’C’ right before the
number, adding leading zeroes to make it always four digits. For
example, the command:
fieldcomb anim12.hdr anim13.hdr anim14.hdr anim15.hdr
will produce two output pictures:
animC0006.hdr & animC0007.hdr
If an odd number of input files is given on the command line, the last
file is held over and used as the first file in the next invocation of
fieldcomb in the same directory. In this way, the program works well
with the "TRANSFER" facility of ranimate(1), which does not guarantee
an even number of frames will be passed every time.
If only two input files are given, the -f option may be used to specify
a different output name of the user’s choosing.
If the -r option is specified, then the input files will be removed
once they have been combined.
Work on this program was sponsored by Iebele Abel.
