Re: [iText-questions] tiff2pdf with jbig2
Hi Paulo,
yesterday the unreadable pdf had this:
2 0 obj /Filter/JBIG2Decode/Type/XObject/Length 21289/BitsPerComponent
1/Height 805306624
This morning I put the code into another system and now I get:
2 0 obj /Filter/JBIG2Decode/Type/XObject/Length 21289/BitsPerComponent
1/Height 1779
and Reader do OPEN it !!
Again, I want to thank you for your assistance.
Have a nice day.
Giuseppe.

Yes, I did set it.
(I copied the code as is. I just put some try/catch and import.)

[iText-questions] tiff2pdf with jbig2
At present on our iSeries(as400) we use iText/tiff2pdf to create pdf from scanned tiff documents. We produce thousands of documents per day and this works perfecty. However because these pdf's should be archived on optical disks and kept for one year (and because optical media cost a lot) we are intereted in reducing the final size of the document. We have been able to port leptionlib and jbig2 on our system and now we can get a output. and output.sym from a tiff image that is 35 to 60 % less that a tiff g4 image. Python script can generate a pdf from it, but we would prefer a java solution. Is there a way to implement iText to include this jbig2 compressed image instead of tiff ? Thanks.
