Okay, I am trying to replace some words in documents and use
text.height to "delete" these words. Here is an example document :

The getHeightDir() is not the best strategy, for the reason I mentioned
yesterday. In your case, you should call getPath() on the glyphs and get
the bounding box. Or just get the font bounding box (there's a method)
height, however that one is often too high, so there's a risk that you
blank the line above.
But thanks for the file, I'll try to find out why it is different. The
heights in 1.8 are surprising, usually they are never so "perfect" (as I
said yesterday). And for some reason, in 1.8 the height of the last
glyph is slightly different although it is all in one string.
1.8:

Hello,
I have noticed that the PrintTextLocations example in 1.8 and 2.0
gives different results for text.getHeightDir(). In 1.8 the value
seems to be right, but in 2.0 it is too small. I tried with some
PDFBox created documents. Is this a bug ?
Maybe, maybe not. The height is a heuristic value to help with text
extraction, which is sometimes computed differently in 2.0, and it is
usually about the height of an "a". Please upload the PDF.
