| 3 |  |  | .SH NAME | 
| 4 |  |  | fieldcomb - combine two or more field frames for video animation |

| 16 |  |  | .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 | greg | 1.2 | file names by 2, inserting a 'C' right before the number, adding | 
| 34 |  |  | leading zeroes to make it always four digits. | 
| 35 | greg | 1.1 | For example, the command: | 
| 36 |  |  | .IP "" .2i | 
| 37 |  |  | fieldcomb anim12.pic anim13.pic anim14.pic anim15.pic | 
| 38 |  |  | .PP | 
| 39 |  |  | will produce two output pictures: | 
| 40 |  |  | .IP "" .2i | 
| 41 | greg | 1.2 | animC0006.pic & animC0007.pic | 
| 42 | greg | 1.1 | .PP | 
| 43 |  |  | If an odd number of input files is given on the command line, the last file | 
| 44 |  |  | is held over and used as the first file in the next invocation of | 
| 45 |  |  | .I fieldcomb | 
| 46 |  |  | in the same directory. | 
| 47 |  |  | In this way, the program works well with the "TRANSFER" facility of | 
| 48 |  |  | .I ranimate(1), | 
| 49 |  |  | which does not guarantee an even number of frames will be passed every time. | 
| 50 |  |  | .PP | 
| 51 |  |  | If only two input files are given, the | 
| 52 |  |  | .I \-f | 
| 53 |  |  | option may be used to specify a different output name of the user's choosing. | 
| 54 |  |  | .PP | 
| 55 |  |  | If the | 
| 56 |  |  | .I \-r | 
| 57 |  |  | option is specified, then the input files will be removed once they have | 
| 58 |  |  | been combined. |
