1、如何得到一个图片的尺寸大小，输入这样的命令

identify 1.png

1.png PNG 2000x1200 2000x1200+0+0 16-bit DirectClass 21.7kb
2、拼图
横向拼接

convert 1.png 2.png +append result1.png

这样图片就变成了一行两列的图了
纵向拼接

convert 1.png 2.png -append result2.png

这样图片就变成了两行一列的图了
3、放大缩小

convert -resize 100x100 1.png n.png

100x100是图片的尺寸，也可以用百分比，50%x50%
4、图片翻转
上下翻转：

convert -flip 1.png 2.png

左右翻转：

convert -flop 1.png 2.png

1.png 是原始的图片，而2.png是翻转之后的图片
5、单色
把图片变为黑白颜色：

convert -monochrome 1.png 2.png

6、加噪声

convert -noise 3 1.png 2.png

7、油画效果
我们可以用这个功能，把一张普通的图片，变成一张油画，效果非常的逼真

convert -paint 4 1.png 2.png

8、旋转
把一张图片，旋转一定的角度：

convert -rotate 30 1.png 2.png

上面的30，表示向右旋转30度，如果要向左旋转，度数就是负数。
9、炭笔效果

convert -charcoal 2 1.png 2.png

形成炭笔或者说是铅笔画的效果。
10、散射
1）毛玻璃效果：

convert -spread 30 1.png 2.png

2）漩涡
以图片的中心作为参照，把图片扭转，形成漩涡的效果：

convert -swirl 67 1.png 2.png

3）凸起效果
用-raise来创建凸边：

convert -raise 5x5 1.png 2.png
