LutBuilderaT A class for building a MorphLut from a descriptive language
|
|
The input patterns is a list of a strings sequences like these::
|
|
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)
|
- M - Mirroring
|
|
Example::
|
|
lb = LutBuilder(patterns = ["4:(... .1. 111)->1"])
|
lut = lb.build_lut()
