2 * filter to tile a serie of image in a single, bigger, image
6 * xtile: number of tile on the x axis (5)
7 * ytile: number of tile on the y axis (5)
8 * xytile: when write the image, it can be different then xtile * ytile
9 * (for example you can write 8 * 7 tile, writing the file every
10 * 50 frame, to have one image every 2 seconds @ 25 fps ).
11 * start: pixel at the start (x/y), default 2
12 * delta: pixel between 2 tile, (x/y), default 4
14 * For example a valid command line is:
15 * ... -vf tile=10:5:-1:4:8 ...
16 * that make images of 10 * 5 tiles, with 4 pixel at the beginning and
17 * 8 pixel between tiles.
19 * The default command is:
20 * ... -vf tile=5:5:25:2:4
22 * If you omit a parameter or put a value less then 0, the default is used.
23 * ... -vf tile=10:5::-1:10
25 * You can also stop when you're ok
27 * (and this is probably the option you will use more often ...)
29 * Probably is good to put the scale filter before the tile :-)
