Tilman Hausherr updated PDFBOX-3418:
------------------------------------
Labels: optimization performance (was: performance)
> Slow string to hex conversion in ToUnicodeWriter
> ------------------------------------------------
>
> Key: PDFBOX-3418
> URL: https://issues.apache.org/jira/browse/PDFBOX-3418
> Project: PDFBox
> Issue Type: Improvement
> Components: PDModel
> Affects Versions: 2.0.2
> Environment: Ubuntu 14.04 LTS
> Reporter: Michael Doswald
> Priority: Trivial
> Labels: optimization, performance
>
> The ToUnicodeWriter.writeTo(OutputStream) method converts a lot of shorts and
> strings to hexadecimal strings. This is done with String.format and therefore
> not very efficient.
> The ToUnicodeWriter.toHex(int) and ToUnitcodeWriter.stringToHex(String)
> methods could be rewritten to generate a char-array and being generally more
> efficient.
