Functions

• circle_marker_path(path, size)
• diamond_marker_path(path, size)
• get_kiva_ctm(self)
• handle_unicode(text)

  Returns a latin1 encoded 8-bit string from 'text'

• init(self, ary_or_size, pix_format = 'bgra32', interpolation = 'nearest', bottom_up = 1)

  When specifying size, it must be a two element tuple. Array input is always treated as an image.

  This class handles the polymorphism of the underlying template classes for individual pixel formats.

• is_array(obj)
• is_correct_type(obj, numeric_type)
• is_sequence(arg)
• is_sequence(arg)
• numpy_check(obj, typecode, exact_size = [ ], must_be_contiguous = 1, allow_coersion = 0)
• points_in_polygon(pts, poly_pts, use_winding = False)

  Test whether point pairs in pts are within the polygon, poly_pts.

  Parameters

  pts

  an Nx2 array of x,y point pairs (floating point). Each point is tested to determine whether it falls within the polygon defined by poly_pts.

  poly_pts

  an Mx2 array of x,y point pairs (floating point) that define the boundaries of a polygon. The last point is considered to be connected to the first point.

  return

  a 1D array of integers. 1 is returned if the corresponding x,y pair in pts falls within poly_pts. 0 is returned otherwise.

  This algorithm works for complex polygons.

  Note: If the test point is on the border of the polygon, this algorithm will deliver unpredictable results; i.e. the result may be "inside" or "outside" depending on arbitrary factors such as how the polygon is oriented with respect to the coordinate system.

                   ( 15.0, 15.0)))
