问题
When I tried converting a picture via :
convert image.tiff image.pdf
It thorws the error:
convert: no images defined `mosaic.jpeg' @ error/convert.c/ConvertImageCommand/3187.
I tried installing and reinstalling imagick , libtiff and jpeg. But it didn't help. It used to work on the same machine (Mac Mavericks) but I had to reboot my machine and reinstall everything, and now it doesn't work. Thank you.
**(UPDATE) Issue Resolved: **
Installed GraphicMagick instead and worked!
回答1:
Are you using homebrew? If not, I would really recommend it - I use it for everything from ImageMagick to exiftool, ffmpeg, 7zip, openssl, netcat, jhead, gawk, gnuplot, GNU coreutils, GNU parallel etc.
Once you install it, all you do is
brew install libtiff
brew install fontconfig
brew install ghostscript
brew install imagemagick --with-fontconfig --with-ghostscript --with-libtiff
If you already have homebrew, and you installed ImageMagick without any of the extra options, you can do this:
brew list # to see what you have got
brew install <whatever is missing out of libtiff, fontconfig, ghostscript>
brew reinstall imagemagick --with-fontconfig --with-ghostscript --with-libtiff
Oh, I forgot to say, your command works fine on my OSX Mavericks with homebrew.

On a Mac, you can also cd into the directory of your image, and use:
sips -s format pdf input.tiff --out output.pdf
