class Region.Region(config, path)

This is the abstract parent class of every Region type. Every concrete Region class should inherit from me. A Region represents a region of a screen. The region could be the entire screen or a subset of it.

Parameters:

  • config: a <no title> object

  • path: the path to the image file to load or None for an empty Region

count_color(color)

Parameters:

  • color: the color to count

Return: the number of times that color appeared in this region

debugprint(rect=(), verbose=False)

Print a text version of the region to stdout. sys.stdout.write is used instead of print in order to have finer control of the formatting.

find_colors(colors)

This will search this region and find rectangles made of pixels containing only values from the list provided.

Parameters:

  • colors: a list of color values to be included as part of the match

Return: a list of tuples of tuples. The “outer” tuple defines the rectangle of the match, while the “inner” tuples are the upper left and lower right corners of the rectangle

find_in_region(hay, rect=(), debug_match=False)

Treating myself as the needle try to find any places in the haystack we match.

Parameters:

  • hay: a <no title> that should be searched for instances of myself

  • rect: the points defining a rectangle that restricts the regions for which matches will be accepted

Return: a list containg tuples of x, y coordinates that are the upper left corner of the region matching me

find_regions(needle, rect=(), debug_match=False)

Treating myself as the haystack try to find any places that match the needle.

Parameters:

  • needle: an <no title> that should be found within myself

  • rect: the points defining a rectangle that restricts the region that should be searched

Return: a list containing tuples of x, y coordinates that are the upper left corner of the region matching the needle

from_array(array)

Load the contents of this image from a multidimensional numpy array.

Parameters:

  • array: the 2D numpy array for this image

get_row(ind)

Parameters:

  • ind: the row index (with row 0 being the top row counting down)

Return: an entire row of pixels as a Sequence

get_size()

Return: a tuple containing the height and width of this region

get_sub_region(upper_left, lower_right)

Get a region of this region defined by the two corners of a rectangle

Parameters:

  • upper_left: a row, col (tuple-like) of the upper left corner

  • lower_right: a row, col (tuple-like) of the lower right corner

get_value_at(x, y)

Return the value (usually the color) of the pixel at the given coordinates.

Parameters:

  • x: the column to check

  • y: the row to check

Return: the value of the given pixel/location

is_black(x, y)

Parameters:

  • x: the column to check

  • y: the row to check

Return: True if the pixel at the given row and column is black

is_white(x, y)

Parameters:

  • x: the column to check

  • y: the row to check

Return: True if the pixel at the given row and column is white

match_at(needle, corner)

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

Parameters:

  • needle: a <no title> 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

save_as_png(path)

Save this Region to the given path (overwriting an existing file if there is one) as a PNG file.

Parameters:

  • path: the location of the file to create

Return: True if successful, False otherwise

show(filename='/tmp/region.png')

Display the region on the screen using a standard unix viewer

show_async(filename=None)

Display the region on the screen using a standard unix viewer

use_exact_matching()

No matter the default, this region should expect only an exact match to be accepted.

Region.get_region(config, path=None, cache=None)

Use the <no title> object to determine the correct type of Region to return. If caching is turned on a combination of config object and path will return the same object each time.

Parameters:

  • config: a <no title> object

  • path: optionally the path to the image to load, can be None to get an empty image

  • cache: a boolean whether or not it’s acceptable to store this object in the cache or return one that’s already there

Return: a concrete instance of Region
