Hi there!

I'm using ImageMagick Command Line tools to convert tiffs to png, resize them and remove the background by using clip (each tiff has an path)

Command without resizing:

Code: Select all

convert go.tif -alpha transparent -clip alpha.png

On my Ubuntu VM it works perfectly:

Code: Select all

Version: ImageMagick 6.6.9-7 2014-03-06 Q16 http://www.imagemagick.org
#================================
root@precise64:/var/www/sh/test# convert -list format | grep TIFF
      EPT  EPT       rw-   Encapsulated PostScript with TIFF preview
     EPT2  EPT       rw-   Encapsulated PostScript Level II with TIFF preview
     EPT3  EPT       rw+   Encapsulated PostScript Level III with TIFF preview
   GROUP4* TIFF      rw-   Raw CCITT Group4
     PTIF* TIFF      rw+   Pyramid encoded TIFF
     TIFF* TIFF      rw+   Tagged Image File Format (LIBTIFF, Version 3.9.5)
   TIFF64* TIFF      ---   Tagged Image File Format (64-bit) (LIBTIFF, Version 3.9.5)
#================================

But on my production server (a managed server without direct rights to install packages) the convert command exits with this error message:

Code: Select all

convert.im6: no decode delegate for this image format `go.tif#1' @ error/blob.c/BlobToImage/364.

Data of the prod. server:

Code: Select all

Version: ImageMagick 6.7.7-10 2014-03-08 Q16 http://www.imagemagick.org
#================================
$ convert -list format | grep TIFF
      EPT  EPT       rw-   Encapsulated PostScript with TIFF preview
     EPT2  EPT       rw-   Encapsulated PostScript Level II with TIFF preview
     EPT3  EPT       rw+   Encapsulated PostScript Level III with TIFF preview
   GROUP4* TIFF      rw-   Raw CCITT Group4
     PTIF* TIFF      rw+   Pyramid encoded TIFF
     TIFF* TIFF      rw+   Tagged Image File Format (LIBTIFF, Version 3.9.6)
   TIFF64* TIFF      ---   Tagged Image File Format (64-bit) (LIBTIFF, Version 3.9.6)
#================================

BTW: On all tested systems i got this Warning:

Code: Select all

convert.im6: go.tif: wrong data type 7 for "RichTIFFIPTC"; tag ignored. `TIFFReadDirectory' @ warning/tiff.c/TIFFWarnings/768.

That is just a warning about some text field that IM does not understand. Tiff has lots of those non-standard fields. This can be ignored.

With respect to the path issue, there has been a bug report about IM not recognizing non-alternating direction paths. Check the Bugs and Developers forums.

The report is here viewtopic.php?f=2&t=25882

so there is no way to fix this at the moment?

Cause this error causes that the png's don't have a transparent background.

Some bug fixes to -clip paths have been fixed and are now in the 6.8.9.6 beta. You can download that and try it.

The server hosters found the problem. The reason was that the package "libmagickcore5-extra" was missing. Now it works properly.

But thanks for your feedback!
