��������δ��д�ĵ������в����б�

Indicates that subsequent commands up to a DrawPopPattern() command comprise the definition of a named pattern. The pattern space is assigned top left corner coordinates, a width and height, and becomes its own drawing space. Anything which can be drawn may be used in a pattern definition. Named patterns may be used as stroke or brush definitions.

����

pattern_id

the pattern Id

x

x coordinate of the top-left corner

y

y coordinate of the top-left corner

width

width of the pattern

height

height of the pattern
