pdfGetNumPapersW
Get the number of available paper sizes (Unicode).
int pdfGetNumPapersW(wchar_t *printerName)
This function returns the number of available paper sizes on the
specified printer.
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).
C:
wchar_t paperName[256];
int nPapers, paperID, w, h, i;
nPapers = pdfGetNumPapersW(printerName);
for (i = 0; i < nPapers; ++i) {
pdfGetPaperNameW(printerName, i, paperName, sizeof(paperName) / sizeof(wchar_t));
paperID = pdfGetPaperIDW(printerName, i);
pdfGetPaperSizeW(printerName, i, &w, &h);
printf("paper %d: id=%d name=%ls size=%.1fx%.1fmm\n",
i, paperID, paperName, 0.1 * w, 0.1 * h);
