Patterns are quite general, and have many uses; for example, they can be used
to create various graphical textures, such as weaves, brick walls, sunbursts,
and similar geometrical and chromatic effects.
Patterns are specified in a special family of color spaces named Pattern, whose
'color values' are PatternColor objects instead of the numeric component values
used with other spaces. Therefore PatternColor is to pattern color space what is
ColorPt to all other color spaces.
A tiling pattern consists of a small graphical figure called a pattern cell.
Painting with the pattern replicates the cell at fixed horizontal and vertical
intervals to fill an area. The effect is as if the figure were painted on the
surface of a clear glass tile, identical copies of which were then laid down
in an Array covering the area and trimmed to its boundaries. This is called
tiling the area.
The pattern cell can include graphical elements such as filled areas, text,
and sampled images. Its shape need not be rectangular, and the spacing of
tiles can differ from the dimensions of the cell itself.
The order in which individual tiles (instances of the cell) are painted is
unspecified and unpredictable; it is inadvisable for the figures on adjacent
tiles to overlap.
