Chromium bridge
webPDF uses the Chromium browser to convert HTML content (e.g., in e-mail documents). The browser is integrated and managed with the Chromium bridge. More specifically, webPDF will start the Chromium browser as a separate process when the server starts and will communicate with the browser via a socket connection. The Chromium browser installation being used will be found in the chromium/ webPDF subdirectory.
The Chromium bridge is used by the "Converter" and "URLConverter" web services.
The "Converter" web service uses the Chromium bridge in order to directly convert HTML content, as well as to convert file formats that use HTML content internally. Examples include EML and MSG documents, but also formatting for text contents that need to be optically processed, such as text and source code documents.
The "URLConnerter" web service converts the passed URL to a PDF document using the Chromium bridge.
Browser starting port
Using the admin page of the web services in the portal, the port of the Chromium browser can be adjusted under "Converter". If the value is "0", the Chromium browser will look for an available port itself when starting. If you want to set a specific port instead, you can use the "Port" setting to do so.
If you disable the Chromium bridge, it will not be possible to process any HTML content, meaning that certain file formats will no longer be converted and/or processed and that the web services will no longer work fully.
