Upgrading ImageMagick on CentOS

Lasso Professional 8.6 and Lasso 9 Server for CentOS 5 includes native support for ImageMagick 6.2.8, the latest official package. However, this package does not reflect the newer updates for ImageMagick. Therefore, LassoSoft, Inc. recommends installing ImageMagick 6.6.5 on CentOS 5, along with a new ImageTag module if running Lasso Professional 8.6.

ImageMagick 6.6.5 installation

  • Uninstall ImageMagick-6.2.8 
    rpm -e --nodeps ImageMagick.i386 ImageMagick-devel.i386 ImageMagick.x86_64 ImageMagick-devel.x86_64
  • Add the EPEL repository to yum:
    • CentOS 5:
    • rpm -Uvh
    • CentOS 6:
    • rpm -Uvh
  • Follow these instructions to add the RPMForge repository to yum for CentOS 5 or 6
  • Install dependencies for ImageMagick 6.6
    • For 32-bit systems: 
      yum install djvulibre OpenEXR jasper ghostscript librsvg2 libwmf libtool-ltdl
    • For 64-bit systems: 
      yum install djvulibre OpenEXR.x86_64 jasper ghostscript.x86_64 librsvg2.x86_64 libwmf.x86_64 libtool-ltdl.x86_64
    • Systems running CentOS 6 will need the old version of libtool-ltdl installed:
      (32-bit) rpm -ivh --force
      (64-bit) rpm -ivh --force

  • Download and install ImageMagick 6.6.5

ImageTag installation for Lasso Professional 8.6

  • Download and unzip the new ImageTag module
  • Move the new file into "/usr/local/Lasso Professional 8/LassoModules/"
  • Restart Lasso
sudo lasso8ctl restart


If the Image tags do not load run these commands:

cd "/usr/local/Lasso Professional 8/LassoModules/"

The output will look something like this: =>  (0x00d86000) => /usr/lib/ (0x005c8000) => /usr/lib/ (0x00599000)

Ensure that any libraries listed as "not found" are installed in the correct location.
