Sorry, for the delay I was away for a week. > a) use a scratch file PDDocument.load(File file, boolean useScratchFiles)
I could not find a load method that has a boolean parameter to indicate whether to use scratch files. However, If I use the PDDocument#load(File file, RandomAccess scratchFile) and specify a scratch file then I get an Exception which occurs for every page I process. The Exception itself doesn't seem to cause any issue as the resulting PDF looks correct, but it is disconcerting. The stacktrace for the thrown exception looks like: [error] Oct 03, 2015 11:10:50 AM org.apache.pdfbox.pdmodel.font.PDFont parseCmap [error] SEVERE: An error occurs while reading a CMap [error] java.io.IOException: Error: expected the end of a dictionary.

If I use PDDocumentCatalog#getPages() then I get a PDPageNode, but from there it looks like I have to call PDPageNode#getKids() which then just gives me a list of all pages, so I can not see how this would be any more efficient, can someone explain? Also I see that PDFBox 2.0.0 is not yet released but does have an iterator interface on PDPageTree. Is it already stable/reliable enough to use? -- Adam Retter skype: adam.retter tweet: adamretter http://www.adamretter.org.uk --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
