Michael Klink commented on PDFBOX-5023:
---------------------------------------
[~tilman]
{quote}It isn't implemented, either because it is difficult or because people
think it is difficult.{quote}
I think in particular because it does not really match the current text
stripper architecture which mostly works on a glyph-by-glyph base, has font and
positioning information per glyph, and maps back and forth between glyph and
Unicode code point. For an *ActualText* you only have the position and size of
the full string (length of string and number of drawn glyphs need not match),
multiple fonts and other parameters might be used in drawing it, ...
So it's not difficult per se but simply does not fit in well.
