Images not appearing in DAISY and EPUB outputs

Applies to the DAISY and EPUB plug-ins

ImageMagick is a free and open-source cross-platform software suite for displaying, creating, converting, modifying, and editing digital images. GhostScript is an interpreter for the PostScript® language and PDF files. The DAISY and EPUB plug-ins use ImageMagick and GhostScript to process images.

Typefi only supports ImageMagick 6.9 for Windows and macOS.

Typefi’s DAISY and EPUB plug-ins are dependent on ImageMagick 6 and are not compatible with ImageMagick 7. This is due to breaking changes in ImageMagick 7's Shell API (replacing the legacy convert command with the new magick command).

If you are experiencing this issue, please follow the steps in this workaround:

  1. Go to the ImageMagick Download page and download the ImageMagick-6.9.12-14-Q16-x64-static installer. You must download the static version, not the dynamic version.
  2. Run the installer.
  3. Once ImageMagick is installed, go to the Ghostscript Downloads page and install Ghostscript for Windows (32 or 64 bit) using the Ghostscript AGPL release.
  4. Sign in to your Typefi Server as an administrator.
  5. Go to Admin → External Applications → ImageMagick.
  6. Set the custom path as: C:\Program Files\[ImageMagick version number]. For example, C:\Program Files\ImageMagick-6.9.12-13-Q16.
  1. Install Homebrew. Paste /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" into the macOS Terminal. You will be prompted for your administrator password.
  2. Once Homebrew is installed, install ImageMagick and GhostScript.
    • For Intel-based (x64) Macs, paste brew install imagemagick@6 ghostscript into the Terminal.
    • For ARM64-based Macs (M1), paste /opt/homebrew/bin/brew install imagemagick@6 ghostscript into the Terminal.
  3. Sign in to your Typefi Server as an administrator.
  4. Go to Admin → External Applications → ImageMagick.
  5. Set the custom path:
    • For Intel-based (x64) Macs, set the path as: /usr/local/opt/imagemagick@6/bin.
    • For ARM64-based Macs (M1), set the path as: /opt/homebrew/opt/imagemagick@6/bin/.

Any images with transparency in them are converted to an opaque image with a white background.
