/*
|
||||
* filter to tile a series of images in a single, bigger, image |
||||
* |
||||
* The parameters are: |
||||
* |
||||
* xtile: number of tiles on the x axis (5) |
||||
* ytile: number of tiles on the y axis (5) |
||||
* xytile: when writing the image, it can be different than xtile * ytile |
||||
* (for example you can write 8 * 7 tiles, writing the file every |
||||
* 50 frames, to have one image every 2 seconds @ 25 fps ). |
||||
* start: pixels at the start (x/y), default 2 |
||||
* delta: pixels between 2 tiles, (x/y), default 4 |
||||
* |
||||
* For example a valid command line is: |
||||
* ... -vf tile=10:5:-1:4:8 ... |
||||
* that makes images of 10 * 5 tiles, with 4 pixels at the beginning and |
||||
* 8 pixels between tiles. |
||||
* |
||||
* The default command is: |
||||
* ... -vf tile=5:5:25:2:4 |
||||
* |
||||
* If you omit a parameter or put a value less than 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 :-) |
