2025-05-13

ps_delete

(PECL ps >= 1.1.0)

ps_deleteDeletes all resources of a PostScript document

说明

ps_delete(resource $psdoc): bool

Mainly frees memory used by the document. Also closes a file, if it was not closed before with ps_close(). You should in any case close the file with ps_close() before, because ps_close() not just closes the file but also outputs a trailor containing PostScript comments like the number of pages in the document and adding the bookmark hierarchy.

参数

psdoc

Resource identifier of the postscript file as returned by ps_new().

返回值

成功时返回 true, 或者在失败时返回 false
