Andreas Lehmkühler commented on PDFBOX-542:
-------------------------------------------
IMHO, it's sufficient to give us the permission the change the header (I've
already started with that), as described as 3. on the page Jukka and you
mentioned:
"Source File Headers for Code Developed at the ASF
0. This section refers only to works submitted directly to the ASF by the
copyright owner or owner's agent.
1. If the source file is submitted with a copyright notice included in it,
the copyright owner (or owner's agent) must either:
1. remove such notices, or
2. move them to the NOTICE file associated with each applicable
project release, or
3. provide written permission for the ASF to make such removal or
relocation of the notices."
By using JIRA your permission is directly connected to your patch, which should
fullfil our needs to have your permission on the record.
> Support for Adobe CFF/Type2 fonts

> Key: PDFBOX-542
> URL: https://issues.apache.org/jira/browse/PDFBOX-542
> Project: PDFBox
> Issue Type: New Feature
> Components: FontBox, PDModel
> Affects Versions: 0.8.0-incubator
> Reporter: Villu Ruusmann
> Assignee: Andreas Lehmkühler
> Attachments: fontbox-r818793.patch, pdfbox-r823839.patch,

> PDFBox should support embedded font types, most prominently the Adobe
> CFF/Type2 (aka Type1C) font type. The desired functionality includes both
> glyph metrics (for PDF text extraction using
> org.apache.pdfbox.util.PDFTextStripper) and glyph painting (for PDF rendering
> using org.apache.pdfbox.pdfviewer.PageDrawer).
> I have implemented the basics of Adobe CFF/Type2 font specification. If the
> other project members find my work substantial, I would like to see it
> incorporated into FontBox/PDFBox projects. Please see the attached patch
> files.
> Design considerations. A PDF FontFile3 stream can be parsed into CFFFont
> objects by class CFFParser. CFFFont contains a map of glyph names to Type2
> charstrings, which can be converted to Type1 charstrings by class
> CharStringConverter and rendered by class CharStringRenderer. Glyph metrics
> is attained by formatting the result as AFM by class AFMFormatter, which
> plugs nicely with existing PDFBox infrastructure. Glyph painting is attained
> by formatting the result as PostScript Type1 font by class
> Type1FontFormatter, which can be loaded via java.awt.Font#createFont(int,
> InputStream).
> The current implementation does not support synthetic CFF fonts nor CID-keyed
> CFF fonts. Also, the conversion of certain Type2 features (stemming, hinting,
> flex) is missing.
