    float $width,
    float $height
): bool
警告

本函数还未编写文档，仅有参数列表。

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.

参数

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

返回值

成功时返回 true， 或者在失败时返回 false。
