---------------------------------------
Summary: Improve ExtractText utility so that it can extract rotated text automatically
Key: PDFBOX-4371
URL: https://issues.apache.org/jira/browse/PDFBOX-4371
Project: PDFBox
Issue Type: Improvement
Components: Text extraction, Utilities
Affects Versions: 2.0.12, 3.0.0 PDFBox
Reporter: Tilman Hausherr
Assignee: Tilman Hausherr
Fix For: 2.0.13, 3.0.0 PDFBox
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"}}.
