/*
|
|
* 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 :-)
