I am trying to get the size of text (i.e fontsize). In version 1.8, the height of text was somewhat inconsistent, and not there for type 3 fonts, but I thought that was supposed to be all sorted out in v2.0. But version 2 seems to be even more inconsistent than version 1.8.
I am using PDFTextStripper and reading the TextPosition array that comes with each String. I have tried getHeight(), getFontSize(), getFontSizeInPt(), getYScale, and none of them are dependable for a useful answer. They are consistent within a file, but useless for checking if a particular string contains readable size text. Which one of these TextPosition values should be used for this purpose And then do I report bugs on all the files that don't give correct results? FYI - I ran a test with version 2 against 100+ PDF files that come from different sources, and use a mixture of TrueType, Type 0, Type1, Type3 fonts. All of these have text that is font size 8-12pt, as reported by Acrobat. I dumped the size values returned for digit strings in the files (i.e 12345), so that everything should be a full height string. The reported height of text mostly ranged from 2.3 to 7.5 (although one very readable file reported a height of 0). I examined a few files with Acrobat and the files with reported text height of 2.3 and 7.5 both had 9pt fonts. But the other values from TextPosition were worse. The fontsize was a plausible value for only about half of these files, seemed particularly bad on TrueTypeFont's. The fontsize values ranged from 1 to 200. The fontsizeinpt values seemed mostly to be a multiple of fontsize, but even that was inconsistent, often it seems to be the square of the fontsize (like a fontsize of 58 and a fontsizeinpt of 3364), but sometimes simply a multiple of 10. The most accurate value I could find in the TextPosition was getYScale(), which had a plausible value about 90% of the time. But on type3 fonts, it too was inconsistent, often returning values of 1, but also values up to 27. So how should I be finding out the height of text??
