The following example detects and loads custom fonts used within a document. The application obtains a list of all fonts used in the document and loads them from the Google Fonts resource, when required. Loaded fonts are added to the DXFontRepository automatically and made available without additional installation requirements.
Note
Google Fonts are open-source, but read the license agreement to determine usage rights for your particular use case.
The application uses the DocumentIterator API to detect fonts used in a document loaded to the RichEditDocumentServer instance. The application lists them in a table. You can click Load From Google Fonts button for an individual font or click Load all Fonts from Google Fonts to download all.
The fonts are loaded from Google Fonts and added to the DXFontRepository. When all fonts are added to the font collection, click the Download as PDF button to open the resulting document in PDF format.
