identify: no decode delegate for this image format image.tif

Post by Greg Coats »

I am using the Mac OS X binary release of ImageMagick, downloaded today from this web site. While I can successfully start up identify, identify reports that it does not recognize the TIF image format. convert misbehaves in this same way.

identify -version
Version: ImageMagick 6.3.0 11/03/06 Q16 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2006 ImageMagick Studio LLC

ls -l image.tif
-rw-r--r-- 1 gregcoat wheel 1947972 Dec 20 18:29 image.tif
file image.tif
image.tif: TIFF image data, little-endian

identify image.tif
identify: no decode delegate for this image format `image.tif'.


Please advise how to use the Mac OS X binary release of ImageMagick to read and write TIF images.

The Mac OS X binary distribution does not have TIFF support included. We recently switched to a universal build so ImageMagick can run on PowerPC and Intel boxes and we're running into problems building a universal build of the TIFF delegate library.

What raster formats are supported in the official ImageMagick binary for Mac OS X? I see that in addition to TIF no longer being supported, PNG is also not supported. Is JPEG2000 supported? What raster formats are supported?

To determine which formats are supports, simply type this command:
  • idenitfy -list format

I did identify -version and identify -list format and get
Version: ImageMagick 6.3.0 11/03/06 Q16 http://www.imagemagick.org

Format Module Mode Description
-------------------------------------------------------------------------------

* native blob support

So, apparently the official Mac OS X version of ImageMagick does not read nor write ANY raster formats. I fail to see how that is useful to anyone.

Did you set the MAGICK_HOME environment variable? You may need to set the DYLD_LIBRARY_PATH environment as well. See QuickStart.txt.
