ps_begin_page(PECL ps >= 1.1.0) ps_begin_page — Start a new page Description
bool ps_begin_page
( resource
$psdoc
, float $width
, float $height
)
Starts a new page. Although the parameters Though PostScript does not know different page sizes, pslib places a bounding box for each page into the document. This size is evaluated by some PostScript viewers and will have precedence over the BoundingBox in the Header of the document. This can lead to unexpected results when you set a BoundingBox whose lower left corner is not (0, 0), because the bounding box of the page will always have a lower left corner (0, 0) and overwrites the global setting. Each page is encapsulated into save/restore. This means, that most of the settings made on one page will not be retained on the next page. If there is up to the first call of ps_begin_page() no call of ps_findfont(), then the header of the PostScript document will be output and the bounding box will be set to the size of the first page. The lower left corner of the bounding box is set to (0, 0). If ps_findfont() was called before, then the header has been output already, and the document will not have a valid bounding box. In order to prevent this, one should call ps_set_info() to set the info field BoundingBox and possibly Orientation before any ps_findfont() or ps_begin_page() calls.
