Andreas Lehmkühler updated PDFBOX-3826:
---------------------------------------
Attachment: PDFBOX-3628_closeTTF.patch
I'm thinking about closing the TrueTypeFont after embedding it if the ttf was
created by PDFBox and if the font isn't subsetted. It should be safe as all
data is loaded to the ttf and is available without parsing the underlying data
again. I've attached a patch with my proposed changes. WDYT, am I missing
something?
