pdfbox 2.0.0 one PDDocument for multiply using

[Ivan Avdonin <de...@gmail.com>]

Dear all,

I try use pdfbox 2.0.0 with embedded unicode fonts and found that font
loading works near 1000 ms.
font = PDType0Font.load(document, new
FileInputStream("fonts/Arial-Unicode-Regular.ttf"));
fontBold = PDType0Font.load(document, new
FileInputStream("fonts/Arial-Unicode-Bold.ttf"));

But, I need faster. I tried to create one PDDocument with fonts then save
it to byte[]. And when i need to create pdf, I load it from byte[]
document = PDDocument.load(new ByteArrayInputStream(DOCUMENT_TEMPLATE));

But I have a problem. First document is created fine, but next one gets
error:
Exception in thread "main" java.lang.NullPointerException
at org.apache.fontbox.ttf.TTFSubsetter.add(TTFSubsetter.java:106)
at org.apache.fontbox.ttf.TTFSubsetter.addAll(TTFSubsetter.java:123)
at
org.apache.pdfbox.pdmodel.font.TrueTypeEmbedder.subset(TrueTypeEmbedder.java:279)
at org.apache.pdfbox.pdmodel.font.PDType0Font.subset(PDType0Font.java:141)
at org.apache.pdfbox.pdmodel.PDDocument.save(PDDocument.java:983)

Could you suggest how i can improve speed of creating pdf with embedded
unicode fonts?

Thanks

You’re getting that error because you’re sharing the same PDType0Font instance across
multiple documents. You need to create a new PDType0Font for each document.

You could try wrapping the FileInputStream with a BufferedInputStream, that might help?
Maybe also look at using smaller font files, Arial Unicode is pretty large.
