Description

Steps to Reproduce

brew install --with-ghostscript imagemagick
magick --version

prints:

Version: ImageMagick 7.0.8-14 Q16 x86_64 2018-11-11 https://imagemagick.org
Copyright: © 1999-2018 ImageMagick Studio LLC
License: https://imagemagick.org/script/license.php
Features: Cipher DPC HDRI Modules
Delegates (built-in): bzlib freetype jng jp2 jpeg lcms ltdl lzma png tiff webp xml zlib

and convert test.ai test.png throws this error:

convert: no images defined `test.png' @ error/convert.c/ConvertImageCommand/3288.

System Configuration

• ImageMagick version: 7.0.8-14 Q16 x86_64 2018-11-11
• Environment (Operating system, version and so on): macOS 10.14 (18A391)
• Additional information:

IM 7 uses magick and not convert. So try

magick test.ai test.png

Be sure that you have a current version of GS and that it is properly installed. It should show up in

magick --version

as gs or gslib. But I do not see it listed in your version output. So perhaps it did not get installed properly.

On my Mac Sierra, I get

magick -version

which list gslib.

In a terminal you should be able to get the version from

gs --version

Sorry, I forgot to mention that I did brew install ghostscript:

gs --version

then uninstalled imagemagick and installed it again by passing the --with-ghostscript argument.

I uninstalled imagemagick again and ran brew install -v --with-ghostscript imagemagick:

Your log shows a configure script command line of:

./configure --disable-osx-universal-binary --prefix=/usr/local/Cellar/imagemagick/7.0.8-14 --disable-dependency-tracking --disable-silent-rules --disable-opencl --disable-openmp --enable-shared --enable-static --with-freetype=yes --with-modules --with-openjp2 --with-webp=yes --without-fftw --without-pango --without-x --without-wmf

You need to add '-with-gslib' to build ImageMagick with the Ghostscript API. However, if the Ghostscript delegate library is not built, ImageMagick will revert to using the Ghostscript delegate library, 'gs.'

after installing ghostscript I ran brew install imagemagick and it worked with me
