🗃️ Starting and Stopping

📄️ Addresses
Once the webPDF server is running, there will be a series of addresses available. The list below shows the specific addresses that will be available if you are using a local webPDF installation. Make sure to adjust them as necessary for your specific installation.
📄️ Performance
The webPDF server executes its PDF functions via web services. As of this writing, the server features seven web services. Several instances of each web service can be executed in parallel, i.e. per web service end point, several queries can be processed simultaneously.

📄️ Optical character recognition (OCR)
webPDF uses the integrated toolbox "tesseract," version 4.1.1, for character recognition (OCR), i.e. to convert graphics formats to PDF documents with text content. This toolbox is used by the "OCR" web service or the portal page.
📄️ Barcodes
webPDF supports the recognition and creation of barcodes ("Barcode" web service) with various common barcode formats.
📄️ HTML conversion
The "URLConverter" and "Converter" web services make it possible to convert HTML content to PDF format.
🗃️ HTML and SVG export

📄️ Display options
The way in which PDFs are displayed in standard-compliant reader programs can be influenced in webPDF with parameter options in web service "Toolbox". Most of the available display options are associated with a specific display scenario, and are accordingly extremely context-dependent.
📄️ Statistics
webPDF features a statistics service (called "Billing") that keeps a record of all of the web services' operations. A corresponding XML file is created in the "logs/" directory every day.
🗃️ Security

📄️ Fonts
The conversion ("Converter“ web service) of foreign formats and the use of PDF/A conversion ("Pdfa“ web service) requires fonts so that the conversion can be carried out as accurately as possible.
📄️ Reverse proxy
You can run webPDF behind a reverse proxy (hereafter referred to as "proxy") if you do not want the webPDF server to respond to direct requests.
📄️ Trust store
In order for the webPDF server to access an external resource or URL that works with a self-signed SSL certificate, the certificate must be imported into the server’s trust store. This will be the case, for example, when there is external content in mail documents that are being converted and this content needs to be retrieved from a server that works with a “self-signed” certificate.
📄️ Proxy
If the webPDF server needs to retrieve external contents, it normally does so directly. However, there are cases in which webPDF is run on a server that does not have access to external resources or URLs, meaning that it cannot retrieve any content from other servers or from the Internet. However, this access is required, for instance, in order to convert various file formats (e.g., e-mails) when they reference external resources.
📄️ XMP Metadata
Using the "Toolbox" web service and the "xmp" operation, the webPDF server can embed "Extensible Metadata Platform" (XMP) metadata in existing PDF documents.
📄️ Units
If information about positions, lengths or sizes has to be provided in the parameters when calling a web service, then a data type "MetricsType" is usually available, which specifies the unit of the associated positions and measurements.
