Tilman Hausherr updated PDFBOX-4371:
------------------------------------
    Description: In a first step, detect all rotations by analyzing the effective text rendering
matrix. In a second step, do a text extraction for each rotation by prepending an appropriate
transform to the page content stream (so that our text has angle == 0) and then filtering
any rotated text. Test file: the file from PDFBOX-4368.  (was: In a first step, detect all
rotations by analyzing the effective text rendering matrix. In a second step, do a text extraction
for each rotation by prepending an appropriate transform to the page content stream (so that
our text has angle == 0) and then filtering any rotated text. Test file: the file from PDFBOX-4368.
Code posted to the users mailing list, thread {{Extracting page "correctly"}}.)
