.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. |
