ps_begin_template — Start a new template

说明

int ps_begin_template ( resource $psdoc , float $width , float $height )

Starts a new template. A template is called a form in the postscript language. It is created similar to a pattern but used like an image. Templates are often used for drawings which are placed several times through out the document, e.g. like a company logo. All drawing functions may be used within a template. The template will not be drawn until it is placed by ps_place_image().

参数

psdoc: Resource identifier of the postscript file as returned by ps_new().
width: The width of the template in pixel.
height: The height of the template in pixel.

返回值

如果成功则返回 TRUE，失败则返回 FALSE。
