Summary: [PATCH] Fix: "Foreign" characters are not rendered
Key: PDFBOX-1831
URL: https://issues.apache.org/jira/browse/PDFBOX-1831
Project: PDFBox
Issue Type: Bug
Components: FontBox
Affects Versions: 2.0.0
Reporter: John Hewson
This is a patch to fix PDFBOX-1691, I've opened it as its own issue because
it's quite a large patch.
The issue it fixes is that the Type 1 "seac" command was not implemented. Seac
is a command which draws a composite glyph from two other glyphs. This requires
that the Type 1 renderer has access to any of the other rendered glyphs in a
CFFFont, which is why this patch is non-trivial. The major change is that the
CharStringRenderer has been refactored into a new Type1CharString class and the
CharStringConverter has been refactored into a new Type2CharString class. A lot
of code has been moved around, but overall this is a conservative patch, as
most of the code has not changed significantly.
As well as the patch, there are 3 new files:
+ fontbox/src/main/java/org/apache/fontbox/cff/Type1CharString.java
+ fontbox/src/main/java/org/apache/fontbox/cff/Type2CharString.java
+ fontbox/src/main/java/org/apache/fontbox/encoding/StandardEncoding.java
and two deleted files:
- fontbox/src/main/java/org/apache/fontbox/cff/CharStringRenderer.java
- fontbox/src/main/java/org/apache/fontbox/cff/CharStringConverter.java
