# ps_delete

(PECL ps >= 1.1.0)

ps_delete — Deletes 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`。
