Hi,
I am trying to get the bounding box of all content in a page(text,
images, tables, etc) in poppler, but I can’t figure this out.
For example, I want to dublicate the result given by ghostscript:
gs -sDEVICE=bbox golfer.ps
prints out
%%BoundingBox: 0 25 583 732
%%HiResBoundingBox: 0.808497 25.009496 582.994503 731.809445
How can this be done with poppler?
Is that the "real" bounding box or one of the pdf boxes (crop, bleed, etc)?
Cheers,
Albert
Thanks,
Mihai

Not the pdf boxes. I mean the union of all bounding boxes of all
elements (text, images, tables, glyphs, etc) in pdf. Let me explain more.
I tried to loop over all QList<TextBox> but these do not include other
glyphs in the pdf (greek sigma - for summation in latex) or maybe
poppler does not see it as a text:
QList<Poppler::TextBox*> wholetext = pdfPage->textList();
//float minX, maxX, minY, maxY;
QRectF unitedTextbbox, textbbox;
for(int i=0; i<wholetext.size(); ++i){
Poppler::TextBox* textBox = wholetext.at(i);
textbbox = textBox->boundingBox();
if(i==0){
unitedTextbbox=textbbox;
}else{
unitedTextbbox=unitedTextbbox.united(textbbox);
}
}
This works great when there is simple text in pdf, but when there are
other symbols it does not. I need something like the example above but
to include all elements in the pdf. I'll go and use only poppler
(without qt4 wrapper) if I can have this.
Cheers,
Mihai
