@ohos.font (Custom Font Registration)

The font module provides APIs for registering custom fonts.

NOTE

The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.

The functionality of this module depends on UI context. This means that the APIs of this module cannot be used where the UI context is unclear. For details, see UIContext.

Since API version 10, you can use the getFont API in UIContext to obtain the Font object associated with the current UI context.
