Answer 2

I have encountered a similar problem with TIFF files on ImageMagick v7.0.4-5 on Windows 7.

If this question concerns a Windows OS, then the cause is that Windows can't find the Jpeg (in my case, TIFF) file library (DLL).

Cause

I had installed ImageMagick without adding it to the Windows $PATH.

Error message

This resulted in error

identify: unable to load module 'C:\Program Files\ImageMagick-7.0.4-Q16\modules\coders\IM_MOD_RL_TIFF_.dll':
The specified module could not be found.
 @ error/module.c/OpenModule/1279.
identify: no decode delegate for this image format `TIFF'
 @ error/constitute.c/ReadImage/509.

Solution

• Re-install ImageMagick and do add it to the $PATH, so that it can find libtiff. Restart your command shell as well.
• First cd into ImageMagick's install folder before executing it.

Answer 3

on Ubuntu 16, I had to install the following first (this was not a dev machine but a server):

sudo apt-get install autoconf automake autotools-dev libtool pkg-config 

then to enable the PNG and JPG delegates :

sudo apt-get install libpng12 libpng12-dev libjpeg libjpeg-dev

followed by

./configure

(Which should now show that the delegates are enabled)

and then rebuild (make clean && make then sudo make install)

substitude the × in -resize 600×600 with a capital X and it should work.
