[poppler] Analysing 3 pages at a time with one function

[Alec Taylor]

Good morning,

How do I analyse 3 pages at a time, using the one function?

Thanks for all suggestions,

Alec Taylor

FYI: You'll find my attempt below

[utils/pdftohtml.cc]

<snipped>

GBool analyseThree(PDFDoc*, SplashOutputDev*, int, int, int);

int main(int argc, char *argv[]) {

<snipped>

      for (int pg = firstPage; pg <= lastPage; ++pg) {
        if(!generateHeaderFooter)
        doc->displayPage(splashOut, pg,
                         72 * scale, 72 * scale,
                         0, gTrue, gFalse, gFalse);
        else
            if(pg+1<lastPage && pg+2<lastPage)
                analyseThree(*doc, *splashOut, pg, pg+1, pg+2);

        SplashBitmap *bitmap = splashOut->getBitmap();

        imgFileName = GooString::format("{0:s}{1:03d}.{2:s}",
            htmlFileName->getCString(), pg, extension);

        bitmap->writeImgFile(format, imgFileName->getCString(),
                             72 * scale, 72 * scale);

        delete imgFileName;
      }

GBool analyseThree(PDFDoc *doc, SplashOutputDev *splashOut, int first,
int second, int third) {
    doc->displayPage(splashOut, first, 72 * scale, 72 * scale, 0,
gTrue, gFalse, gFalse);
    doc->displayPage(splashOut, second, 72 * scale, 72 * scale, 0,
gTrue, gFalse, gFalse);
    doc->displayPage(splashOut, third, 72 * scale, 72 * scale, 0,
gTrue, gFalse, gFalse);

    return gTrue;
}
