Alfred created PDFBOX-4916:
------------------------------
Summary: Use dedicated scale and translate operations instead of
concatenate where possible
Key: PDFBOX-4916
URL: https://issues.apache.org/jira/browse/PDFBOX-4916
Project: PDFBox
Issue Type: Improvement
Components: Text extraction
Affects Versions: 2.0.20, 3.0.0 PDFBox
Reporter: Alfred
LegacyPDFStreamEngine does translating and scaling using the generic
concatenate matrix ops.
A scale or a translate require much less multiplications and so there's room to
improve there.
I have the code ready and I will submit a patch right away.
