gscan2pdf G4-Compression: chunked ccitt g4 tif not supported

[Thomas Mayer]

Binary package hint: gscan2pdf

What I did:
- Scan a page with a scanner
- Click on "Save"
- Choose G4 Compression
- and Save in new File

Then comes an error message:
Fehler beim Einbinden der Bilddatei im tif-Format ins PDF: chunked ccitt g4 tif not supported. at /usr/share/perl5/PDF/API2/Resource/XObject/Image/TIFF.pm line 270.

The pdf cannot be stored in G4.

In case I choose standard compression the pdf can be stored.

I have a fresh ubuntu karmic installed with all updates and all dependencies of gscan2pdf.

In ubuntu jaunty, I was able to store with G4-Compression in gscan2pdf.

This might be the same as debian bug #549653

The attached G4 compressed TIFF, together with the g4test.pl test script demonstrate the problem:

chunked ccitt g4 tif not supported. at /usr/share/perl5/PDF/API2/Resource/XObject/Image/TIFF.pm line 270.

the same problem persists using current ubuntu lucid 10.04 with all updates installed

[Jeffrey Ratcliffe (jeffreyratcliffe)]

The only fix I have for this is to disable G4 encoding for PDFs upstream until I can find a replacement for PDF::API2, which is no longer maintained.

[Jeffrey Ratcliffe (jeffreyratcliffe)]

g3 and g4 were disabled in gscan2pdf 0.9.30, and therefore in the current maverick package
