Windows Driver Kit DDI reference (nf-winppi-gdigetpagehandle)

Description

The GdiGetPageHandle function returns a handle to the specified page within a print job.

Parameters

`SpoolFileHandle`

Caller-supplied spool file handle, obtained by a previous call to GdiGetSpoolFileHandle.

`Page`

Caller-supplied page number.

`pdwPageType`

Caller-supplied pointer to a location that receives the page type. The possible page types are shown in the following table:

Page Type	Meaning
EMF_PP_FORM	The page is a form or has a watermark. (Not currently supported.)
EMF_PP_NORMAL	The page is a normal page.

Return value

If the operation succeeds, the function returns TRUE. Otherwise the function returns FALSE, and an error code can be obtained by calling GetLastError.

Remarks

The GdiGetPageHandle function is exported by gdi32.dll for use within a print processor's PrintDocumentOnPrintProcessor function.

Print processors must obtain a page handle before calling GdiPlayPageEMF to draw a page. If a Page value is specified that is too large, the function returns ERROR_NO_MORE_ITEMS.

For additional information, see Using GDI Functions in Print Processors.
