| /* |
| * filter to tile a serie of image in a single, bigger, image |
| * |
| * The parameters are: |
| * |
| * xtile: number of tile on the x axis (5) |
| * ytile: number of tile on the y axis (5) |
| * xytile: when write the image, it can be different then xtile * ytile |
| * (for example you can write 8 * 7 tile, writing the file every |
| * 50 frame, to have one image every 2 seconds @ 25 fps ). |
| * start: pixel at the start (x/y), default 2 |
| * delta: pixel between 2 tile, (x/y), default 4 |
| * |
| * For example a valid command line is: |
| * ... -vf tile=10:5:-1:4:8 ... |
| * that make images of 10 * 5 tiles, with 4 pixel at the beginning and |
| * 8 pixel between tiles. |
| * |
| * The default command is: |
| * ... -vf tile=5:5:25:2:4 |
| * |
| * If you omit a parameter or put a value less then 0, the default is used. |
| * ... -vf tile=10:5::-1:10 |
| * |
| * You can also stop when you're ok |
| * ... -vf tile=10:5 |
| * (and this is probably the option you will use more often ...) |
| * |
| * Probably is good to put the scale filter before the tile :-) |
