[jira] [Commented] (PDFBOX-5904) Fontbox OpenTypeFont should use isPostScript() internally, not isPostScript
[ https://issues.apache.org/jira/browse/PDFBOX-5904?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17900709#comment-17900709 ]

-----------------------------------------
Which ones? getCFF(), getGlyph(), getPath() ?

>
> Key: PDFBOX-5904
> URL: https://issues.apache.org/jira/browse/PDFBOX-5904
> Project: PDFBox
> Issue Type: Bug
> Components: FontBox
> Affects Versions: 3.0.3 PDFBox
> Reporter: Jxtps
> Priority: Major
>
> OpenTypeFont's isPostScript() is defined as:
> {code:java}
> public boolean isPostScript()
> {
> return isPostScript || tables.containsKey(CFFTable.TAG) || tables.containsKey("CFF2");
> } {code}
> See: https://github.com/apache/pdfbox/blob/trunk/fontbox/src/main/java/org/apache/fontbox/ttf/OpenTypeFont.java
> So it checks for the presence of key tables (CFF, CFF2).
> However, the getters in the class only checks the private variable isPostScript, not the method.
> This causes buggy font files with the wrong version tag but with a CFF table to throw exceptions.
> To fix: replace the internall references to isPostScript by calls to isPostScript().
> Workaround: crack open the module and create a custom class in the same package and have it call setVersion(Float.intBitsToFloat(0x4F54F4F4)), but that kind of sucks.
