class RegionMatcher.RegionMatcher(config, strategy=None)

I am the public inteface to do RegionMatching. My actually matching strategy can be selected at load time by specifing it in the config.

Parameters:

match(haystack, needle, rect)

Look for matches of the needle within the haystack, optionally restricted to only those within the given rectangle.

Parameters:

  • haystack: an Region to search

  • needle: an Region to look for

  • rect: if specified as a 4 element list (or tuple) those are the coordinates of a rectangle to bound the search, otherwise it is ignored, if this argument has only 2 elements they are assumed to be the coordinates of the upper left corner, the remaining corners can be derived from the needle

Return: a list of tuples which are the upper left coordinates that are the start of a match of the needle

match_at(haystack, needle, corner)

Check at a particular location to see if we match the given needle.

Parameters:

  • haystack: a Region to search in

  • needle: a Region to look for

  • corner: a tuple containing the upper left corner to start the match (tuple is in X,Y notation, not Row,Col)

Return: True if the needle is matched there, False otherwise

use_exact_matching()

Have this matching strategy use exact matches only.
