-----------------------------------
Summary: [PATCH] Parser for Type 1 Fonts
Key: PDFBOX-1844
URL: https://issues.apache.org/jira/browse/PDFBOX-1844
Project: PDFBox
Issue Type: Improvement
Components: FontBox
Affects Versions: 2.0.0
Reporter: John Hewson
This patch adds a parser for Type 1 fonts to FontBox and makes use of it in
PDFBox for rendering Type 1 glyphs. This should fix various issues with the JVM
crashing and rendering fonts incorrectly.
It was necessary to modify Type1CharStringParser to handle the `callothersubr` command
and correctly handle subroutines. Likewise, Type1CharString was modified to support
"flex".
This patch does not remove the AWT fallback for non-embedded and standard 14
fonts because am entirely new fallback system is needed and suitable fonts will
need to be shipped as part of PDFBox. This needs to be discussed on the mailing
list and/or in follow-on issue.
Note: To keep this patch small I have not replaced any of the existing ad-hoc
Type 1 parsing code in PDType1Font and preflight. Those classes retain their
original code which can be replaced in subsequent patches/refactoring. I can
open follow-on issues for these.

This are really good news !!
And the timing is perfect as I wanted to start my own implementation this week
:-)
I don't want to slow you down, but this patch is a substantial contribution and
we have to ask you to sign our CLA [1]. I hope that this requirement isn't a
showstopper here, Be sure we won't blame you if you have to decline for any
reason. Feel free to ask if anything is unclear.
I'm going to take care about the patch as soon as the "paperwork" is done!
Thanks in advance!
