I'm getting the following error for tiff commands.

no decode delegate for this image format 'TIFF' @ error/constitute.c/ReadImage/501

I'm running ImageMagick 6.9.0-10 Q16 x86_64 installed via homebrew (http://brew.sh). I also installed libtiff via homebrew. Computer is running OS X Mavericks 10.10.2

I first tried uninstalling ImageMagick (brew uninstall imagemagick && brew cleanup) and reinstalled it just in case it picked up libtiff — no result

convert -list configure yields DELEGATES bzlib mpeg freetype jng jpeg lzma png xml zlib

I tried editing delegates.xml in the CONFIGURE_PATH, commenting out

<!-- <delegate decode="tiff" encode="launch" mode="encode" command=""gimp" "%i""/> -->

and adding

<delegate decode="tiff" encode="launch" mode="encode" command=""libtiff" "%i""/>

Do I need to 'restart' imagemagick in someway so it re-reads the delegates.xml file? Or is there some other step I'm missing?

Thanks for any help or advice

Homebrew seems to be flaky. See viewtopic.php?f=1&t=27264&p=120982&hili ... ew#p120982

How did you install IM? Did you install libtiff at the same location as IM?

If

convert -version

does not list tiff, then it did not get installed properly or at the wrong location for IM to find it.

Does

convert -list format

list TIFF? If not, the same as above is true.

Neither lists tiff

Where should libtiff be installed for proper discovery by IM?

Though it seems that installing manually is faster than trying to fix a flaky homebrew install.

Found the fix on StackOverflow:

Short version is use the below

Thanks for the reply with the Homebrew solution. It should help others who have similar issues.
