.SH DESCRIPTION
|
| 17 |
|
|
.I Fieldcomb
|
| 18 |
|
|
combines two or more field frames into half as many final video frames
|
| 19 |
|
|
for field-based animations.
|
| 20 |
|
|
Normally, the even scanlines in the output are given over to the first,
|
| 21 |
|
|
third, fifth, etc. pictures given on the input, and the odd scanlines are
|
| 22 |
|
|
given over to the second, fourth, sixth, etc. pictures on the input.
|
| 23 |
|
|
This behavior corresponds to the
|
| 24 |
|
|
.I \-e
|
| 25 |
|
|
option, which is set by default.
|
| 26 |
|
|
To reverse this ordering, the
|
| 27 |
|
|
.I \-o
|
| 28 |
|
|
option must be specified.
|
| 29 |
|
|
.PP
|
| 30 |
|
|
Normally,
|
| 31 |
|
|
.I fieldcomb
|
| 32 |
|
|
will name output frames by dividing the numbers on the input field
|
| 33 |
|
|
file names by 2, inserting a 'C' right before the number.
|
| 34 |
|
|
For example, the command:
|
| 35 |
|
|
.IP "" .2i
|
| 36 |
|
|
fieldcomb anim12.pic anim13.pic anim14.pic anim15.pic
|
| 37 |
|
|
.PP
|
| 38 |
|
|
will produce two output pictures:
|
| 39 |
|
|
.IP "" .2i
|
| 40 |
|
|
animC6.pic & animC7.pic
|
| 41 |
|
|
.PP
|
| 42 |
|
|
If an odd number of input files is given on the command line, the last file
|
| 43 |
|
|
is held over and used as the first file in the next invocation of
|
| 44 |
|
|
.I fieldcomb
|
| 45 |
|
|
in the same directory.
|
| 46 |
|
|
In this way, the program works well with the "TRANSFER" facility of
|
| 47 |
|
|
.I ranimate(1),
|
| 48 |
|
|
which does not guarantee an even number of frames will be passed every time.
|
| 49 |
|
|
.PP
|
| 50 |
|
|
If only two input files are given, the
|
| 51 |
|
|
.I \-f
|
| 52 |
|
|
option may be used to specify a different output name of the user's choosing.
|
| 53 |
|
|
.PP
|
| 54 |
|
|
If the
|
| 55 |
|
|
.I \-r
|
| 56 |
|
|
option is specified, then the input files will be removed once they have
|
| 57 |
|
|
been combined.
