IIOException: Error 2 when displaying PDF containing CCITT Group 3 compressed
images
------------------------------------------------------------------------------------
Key: PDFBOX-834
URL: https://issues.apache.org/jira/browse/PDFBOX-834
Project: PDFBox
Issue Type: Bug
Components: PDModel
Reporter: Jeremias Maerki
Assignee: Jeremias Maerki
Fix For: 1.3.0
A client sent me a PDF that failed with:
SEVERE: javax.imageio.IIOException: Error 2
at
com.sun.media.imageioimpl.plugins.tiff.TIFFFaxDecompressor.decodeBlackCodeWord(TIFFFaxDecompressor.java:1389)
com.sun.media.imageioimpl.plugins.tiff.TIFFFaxDecompressor.decodeT6(TIFFFaxDecompressor.java:1140)
com.sun.media.imageioimpl.plugins.tiff.TIFFFaxDecompressor.decodeRaw(TIFFFaxDecompressor.java:680)
com.sun.media.imageio.plugins.tiff.TIFFDecompressor.decode(TIFFDecompressor.java:2514)
It turns out this happens with images using CCITT Group 3 (T.4) compressed
images with no "K" key in the DecodeParams (i.e. K=0). Group 4 is set on the
TIFF which leads to a decoding error. Extracting the TIFF, the software info
field is malformed, too.
