pdfGetPaperIDW
Get a paper size ID (Unicode).
unsigned int pdfGetPaperIDW(wchar_t *printerName, int paperIdx)
This function returns the ID for
the
paperIdx
th available paper size, on the
specified printer.
paperIdx
must be between 0 and n-1, where n is the value
returned by pdfGetNumPapersW
.
The returned value can be passed to pdfPrintSetPaper
.
Note: pdfGetNumPapersW
, pdfGetPaperNameW
,
pdfGetPaperIDW
, and pdfGetPaperSizeW
are just simple
wrappers around Windows functions. There is no requirement to use
these functions if you already know the paper ID that you want to use
(e.g., from calling DeviceCapabilities
with
the DC_PAPERS
argument).
