|

4:(...
|
||||
.1.
|
||||
111)->1
|
||||
|

(whitespaces including linebreaks are ignored). The option 4
|

describes a series of symmetry operations (in this case a

4-rotation), the pattern is described by:

|
||||
- . or X - Ignore
|

- 1 - Pixel is on
|

- 0 - Pixel is off
|

|

The result of the operation is described after "->" string.

The default is to return the current pixel value, which is

returned if no other match is found.

Operations:

- 4 - 4 way rotation

- N - Negate

- 1 - Dummy op for no other operation (an op must always be given)
