Hi Everyone,

I am transforming a TIFF Picture into a JPEG Thumbnail and I get to see this warning: Unknown field with tag 34665 encountered warning.

I am using JMagick 6.0.4

I am using ImageMagick 6.1.8-3 Q16 over Windows 2000 Professionnal Edition Service Pack 4.

So far, what I discovered:

• The Picture gives the warning when using 'identify' : Unknown field with tag 34665
• The Picture gives the warning when opening with 'IMDisplay' utility.
• The Picture have some color loss when opening with IMDisplay ( Red become blue, White becomes Black, etc... )
• The Picture works fine with Adobe Photoshop 7.0 ( The Software that originally created the picture )
• The Picture works fine and is displayable with MS Photo Editor ( Small Application that is installed with MS Office 2000 )
• The Field Tag 34665 is an Adobe Specific ( According to Magick-Users Mailing List )
• The Field Tag 34665 is not present in TIFF 6.0 Specification from 1992 ( >From what I understand from the Spec )
• The Field Tag 34665 is not present in TIFF 6.0 Specification Add-On from 1995 ( From what I understand from the Spec )
• The Field Tag 34665 is not present in TIFF 6.0 Specification Add-On from 2002 ( From what I understand from the Spec )

How can I transform this picture without the problem? Is this a problem with libTIFF or ImageMagick?

I ruled out the JMagick Problem, because I performed the problem with ImageMagick only ( Command-Line Operations ), and the problem presented itself in the same fashion.

Can anyone help?

Thanks,

Claude Houle
