我想做到和windows的桌面一样能把小图片放大为大图片时，是通过平铺填充到大尺寸里，我应该怎么做，我用Imagick搞了半天还是找不到头绪。
Imagick有个Montage工具。
用法如下：
To tile a set of images, allowing ImageMagick to pick the layout for you:
$ montage *.jpg out.jpg
To tile a set of 7 images, arranged in a single row:
$ montage *.jpg -tile 7x1 out.jpg
To tile a set of 5 images, arranged in a single column:
$ montage *.jpg -tile 1x5 out.jpg
To tile a set of 10 images, arranged in two rows:
$ montage *.jpg -tile 5x2 out.jpg
To specify that only a spacing of 2 pixels be used between images in the above setting:
$ montage *.jpg -tile 5x2 -geometry +2+2 out.jpg
Tried with: ImageMagick 6.6.9-7 and Ubuntu 12.04
