/* * 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 :-) * * copyright (c) 2003 Daniele Forghieri ( guru@digitalfantasy.it ) * * This file is part of MPlayer. * * MPlayer is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by * the Free Software Foundation; either version 2 of the License, or * (at your option) any later version. * * MPlayer is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
