Tilman Hausherr commented on PDFBOX-4176:
-----------------------------------------
Ooops, I think you're asking about "First image in tiff is not CCITT T4 or T6
compressed". That is because PDFBox can use the existing compression for TIFF
files with these compressions, i.e. doesn't have to decompress first.
> PDImageXObject doesn't support TIFF although JavaDoc says it does
