Thanks in advance

cvs checkout libtiff

Hi,

I tried to build the source provided by you in previous mail.
But it is not getting build.My platform details are mentioned below

Linux devoutputserver 2.6.18-194.el5 #1 SMP Tue Mar 16 21:52:39 EDT 2010 x86_64
x86_64 x86_64 GNU/Linux.

So I downloaded latest official build tiff-4.0.8 and replace the *.c and *.h
with the ones provided by cvs and build it

After building tiff2pdf is not crashing but it is giving error and file is not
getting generated

./tiff2pdf -o output.pdf /home/madhulika/20170113091505_4548000_N0001P0001.TIF
_TIFFVSetField: /home/madhulika/20170113091505_4548000_N0001P0001.TIF: Bad

tiff2pdf: Can't set directory 3 of input file
/home/madhulika/20170113091505_4548000_N0001P0001.TIF.
tiff2pdf: An error occurred creating output PDF file.

You must run autogen.sh before configure when working from a CVS checkout.

OK, so this is now just a defect of tiff2pdf not working properly in that case.
Probably linked to the multiple directories in the file

Hi,

Could you please ellaborate what is the meaning of multiple directories.

Hi,

Just want to share an observation about the above tif file.
The attached TIF file contain 4 pages but 4th page is also numbered as 03/06
that may be causing error.

Could you please tell me when it is expected to be fixed as customer is blocked
because of this.

Actually this TIFF file is corrupted. The 4th page has a height of 0 :

Directory 3: offset 124404 (0x1e5f4) next 0 (0)
SubFileType (254) LONG (4) 1<2>
ImageWidth (256) LONG (4) 1<1728>
ImageLength (257) LONG (4) 1<0> <-- wrong

This bug tracker is the one of the community project driven by volunteers, so
there's no guarantee if and when a bug will be fixed. If your business depends
on libtiff, then consider contracting a developer to fix it.

Regarding this specific issue, the best fix would probably to have a flag to
skip gracefully over corrupted pages.

Bugzilla is no longer used for tracking libtiff issues. Remaining open tickets,
such as this one, have been migrated to the libtiff GitLab instance at
https://gitlab.com/libtiff/libtiff/issues .

The migrated tickets have their summary prefixed with [BZ#XXXX] where XXXX is
the initial Bugzilla issue number.
