Tile

grid

original 画像を、幅と高さを指定してグリッド状のタイルに切り分ける。各タイルの左端と上端を隣のタイルと重複させるピクセル数を overlap で指定（-g width,height:overlap）。重複が不要な場合は 0 とする。 % resize.rb -g 50,50:0 image.jpg 生成された画像は左上から右方向へ順に 0,0 1,0 2,0 ... 縦方向へ順に 0,0 0,1 0,2 ... と自動的にファイル名がつけられる。 >>> image-grid.jpg -> ./image-grid-0,0.jpg (50x50 @ 0,0) >>> image-grid.jpg -> ./image-grid-1,0.jpg (50x50 @ 1,0) >>> image-grid.jpg -> ./image-grid-2,0.jpg (50x50 @ 2,0) >>> image-grid.jpg -> ./image-grid-3,0.jpg (16x50 @ 3,0) >>> image-grid.jpg -> ./image-grid-0,1.jpg (50x50 @ 0,1) >>> image-grid.jpg -> ./image-grid-1,1.jpg (50x50 @ 1,1) >>> image-grid.jpg -> ./image-grid-2,1.jpg (50x50 @ 2,1) >>> image-grid.jpg -> ./image-grid-3,1.jpg (16x50 @ 3,1) >>> image-grid.jpg -> ./image-grid-0,2.jpg (50x50 @ 0,2) >>> image-grid.jpg -> ./image-grid-1,2.jpg (50x50 @ 1,2) >>> image-grid.jpg -> ./image-grid-2,2.jpg (50x50 @ 2,2) >>> image-grid.jpg -> ./image-grid-3,2.jpg (16x50 @ 3,2) >>> image-grid.jpg -> ./image-grid-0,3.jpg (50x50 @ 0,3) >>> image-grid.jpg -> ./image-grid-1,3.jpg (50x50 @ 1,3) >>> image-grid.jpg -> ./image-grid-2,3.jpg (50x50 @ 2,3) >>> image-grid.jpg -> ./image-grid-3,3.jpg (16x50 @ 3,3)
