${B}USAGE${N}"
$0 [-f|--file] <file> [ -t|--tile ${U}row${N} ${U}col${N} ] [ -d|--dest ${U}dest${N}]
[ -ts|--tile-size ${U}tw${N} ${U}th${N} ] [ -gs|--grid-size ${U}gw${N} ${U}gh${N} ]
[ -os|--out-size ${U}ow${N} ${U}oh${N} ] [ -b|--background ${U}svgcolor${N} ]
${B}PARAMS${N}
${U}file.svg${N}
The input SVG filename
-t, --tile ${U}row${N} ${U}col${N}
Specify the selected tile.
You can specify a range with ${U}num${N}-${U}num${N}
or a list of space-separated ${U}num${N}s (remember quotes)
-d, --dest ${U}dest${N}
Specify the output destination. The output path of each tile is created
appending \`${U}row${N}-${U}col${N}.png' to ${U}dest${N}.
Defaults to ${U}file${N} without \`.svg' extension.
-ts, --tile-size ${U}width${N} ${U}height${N}
Specify the tile size. Defaults to: $TILESIZE_W,$TILESIZE_H
-gs, --grid-size ${U}width${N} ${U}height${N}
Specify the grid size, by number of horizontal/vertical tiles.
Defaults to: $GRID_W,$GRID_H
-os, --out-size ${U}width${N} ${U}height${N}
Specify the size of the output PNG image. Defaults to tile size.
You can also use -ow or -oh to set only width/height. The unset
value is auto-determined by keeping aspect ratio.
-b, --background ${U}svgcolor${N}
Specify the background of the image. Defaults to: $BACKGROUND.
-h, --help
Show this help and exit.
--license
Show license and exit.
--debug
Enable debugging mode.
