Get a paper size.
int pdfGetPaperSize(char *printerName, int paperIdx, int *width, int *height)
This function retrieves the size of the paperIdxth available paper, on the specified printer.

paperIdx must be between 0 and n-1, where n is the value returned by pdfGetNumPapers.

The paper size will be returned in *width and *height, both in tenths of millimeters.

Returns 1 on success, or 0 on failure.

Note: pdfGetNumPapers, pdfGetPaperName, pdfGetPaperID, and pdfGetPaperSize 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).

char paperName[256]; int nPapers, paperID, w, h, i; nPapers = pdfGetNumPapers(printerName); for (i = 0; i < nPapers; ++i) { pdfGetPaperName(printerName, i, paperName, sizeof(paperName)); paperID = pdfGetPaperID(printerName, i); pdfGetPaperSize(printerName, i, &w, &h); printf("paper %d: id=%d name=%s size=%.1fx%.1fmm\n", i, paperID, paperName, 0.1 * w, 0.1 * h); }
