.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. |
