I've installed ImageMagick on my Mac and am trying to convert a TIFF image to a JPEG image using the PHP API that is provided by the ImageMagick extension. When I try to do that I get the following error:
no decode delegate for this image format
When I do a convert image1.tiff image1.jpg on the command line it works.
For some reason the PHP extension for Imagick thinks the TIFF delegate is not installed when it clearly is. Why would I get different results and how could I fix this?
I found the solution. I had installed both ImageMagick and the PHP ImageMagick extension php53-imagick using Homebrew. When installing them this way you don't have many options in terms of configuration. php53-imagick was configured to use the Homebrew installation of ImageMagick.
What I did to solve the problem was download and compile the source of the Imagick PHP extension myself. The key configuration that you have to make is ./configure --with-imagick=/user/local or wherever your ImageMagic/wand folder is.
The imagick.so will appear in the modules directory and you'll need to add it to the php.ini
Coming from a different question: There's a more convenient solution in Homebrew with the command
brew install libtiff
brew install imagemagick --with-libtiff
(see Imagemagick can not find deletegates library for .tiff format on mac os x mountain lion for reference)
