Hi,

Then you'll have to investigate this yourself... try other viewers (Adobe, Chrome, Edge Ghostscript, PDF.js) to see what they display, or download our source code and open CCITTFaxDecoderStream.java. There replace the exception with a "return", build and then see whether it gets better or not.

Hi,

we are using PDFBox 2.0.12 to convert PDF files to JPEG images. It works pretty good, but 
currently there are a few files that can't be converted. An "IOException: Unknown 
code in Huffman RLE stream" is thrown in the CCITTFaxDecoderStream.decodeRun() 
method. Now I'm not sure what this exception means ... is this typically the case when 
the PDF file is corrupt?

Yes... please share the PDF (upload to sharehoster)
