Configure Apryse / PDFTron Local Fonts in PowerWeb

Configure Meridian PowerWeb to use Apryse (formerly PDFTron) fonts from a local folder. By default, Apryse downloads fonts the internet if they aren’t available in your local Meridian installation. This allows you to have access to all fonts Apryse provides, even if your environment restricts internet access.

1. In your web server, download the font package.

2. Extract the downloaded file to a subfolder, such as Fonts.

   We recommend the C:\inetpub\AMM\Src\PDFTron folder path.

3. Create a virtual directory in IIS for the folder that contains the font files.

   This directory must be accessible from the web. Use the Anonymous Authentication to allow access.

4. In IIS, add the following file extensions:

   • .lzma with MIME type font/ttf

   • .brotli with MIME type font/ttf

5. If your environment uses CORS, set the HTTP header Access-Control-Allow-Origin to *.

6. In IIS Manager, go to Default web site > Advanced settings.

7. In Enabled protocols, select HTTPS.

   Do not use HTTP protocol. PDFTron forces HTTPS, even if HTTP is specified.

8. Open the Windows Registry Editor and go to:

   HKEY_LOCAL_MACHINE\SOFTWARE\Cyco\AutoManager Meridian\CurrentVersion\WebLink

9. Add a String value named PDFTronFontLocation.

10. Set the registry value to the web location of the font files.

    For example, if your fonts are in C:\inetpub\AMM\Src\PDFTron\Fonts, the registry key value is https://<YourPowerWebServer>/AMM/Src/PDFTron/Fonts.

    You can also use a relative path if the virtual directory is under Default web site in IIS, such as /PDFTronFonts.
