用python对图片进行错位处理

1、这是纵向错位：def f(i,j): return i+0.1/3*abs(int(30*j%2))def g(i,j): return j

2、横向错位：def f(i,j): return idef g(i,j): return j+0.1/3*abs(int(30*i%2))

3、双向错位：def f(i,j): return i+0.1/3*abs(int(30*j%2))def g(i,j): return j+0.1/3*abs(int(30*i%2))

4、增加错位频率：def f(i,j): return i+0.1/10*abs(int(100*j%2))def g(i,j): return j+0.1/10*abs(int(100*i%2))

5、斜边错位：def f(i,j): return i+0.1*(((10*j)%2))def g(i,j): return j

6、def f(i,j): return i+0.1/20*(((200*j)%2))def g(i,j): return j+0.1/20*((200*i%2))

7、曲边错位：def f(i,j): return i+0.1*((10*j%2-1)**2)def g(i,j): return j

8、def f(i,j): return i+0.1/3*((30*j%2-1)**2)def g(i,j): return j

9、def f(i,j): return i+0.1*((10*j%2-1)**2)def g(i,j): return j+0.1*((10*i%2-1)**2)
