Tilman Hausherr commented on PDFBOX-2594:
-----------------------------------------
JBIG2Globals is supported since PDFBOX-1999, but our code is not
levigo-specific, i.e. we can't call setGlobals(). In theory, one could use a
different JBIG2 decoder. (we tried JPedal years ago but it didn't work at that
time)
I just looked whether I have the file of PDFBOX-1999, but I don't. It was
probably a "confidential and delete after testing" file and I really do this.
