Hello,
I'm trying to find a way to determine the font-size used in a pdf document =
using pdfbox.
I understand how to get at the fonts using code like:
List allPages =3D document.getDocumentCatalog().getAllPages();
PDPage firstPage =3D (PDPage)allPages.get( 0 );
PDResources pdResources = firstPage.findResources();
Map<String, PDFont> fonts = pdResources.getFonts();
however, this does not get you the font-size such as 12pt... etc. I tried:
PDResources pdResources = firstPage.findResources();
Map<String, PDExtendedGraphicsState> graphicsStates =
pdResources.getGraphicsStates();
but this just returns null for graphicStates so my document must not have a=
graphics dictionary. What am I to do.
The goal for me is to figure out how approximately how many lines of text a=
re on a page and how many columns. In order
to figure out how many columns=2C I need to know about how wide the average=
character in the charset is in pixels, and
in order to know that I need the font-size. Perhaps there is a way I can ca
lculate this information using the PDFont data
that I do have, however, I haven't been able to figure it out. Any help
would be appreciated.
Thanks,
Tom
