Replace missing font

GroupDocs.Viewer Cloud enables you to set default font name which may be useful in following cases:

  1. You want to generally specify the default font to fall back on if a particular font in a document cannot be found during rendering;
  2. The document uses a font that contains non-English characters and the you want to make sure that any missing font is replaced with one which has the same character set available.

Following code snippet shows how to set default font name.

API Usage

There are steps that usage of GroupDocs.Viewer Cloud consists of:

  1. Upload input document into cloud storage
  2. Render document or get document info
  3. Download rendered document from storage

Steps 1 and 3 are storage operations, please refer to this File API documentation for usage details.

Swagger UI lets you call this REST API directly from the browser.

SDK examples

The API is completely independent of your operating system, database system or development language. We provide and support API SDKs in many development languages in order to make it even easier to integrate. You can see our available SDKs list here.
