    Compilation and Building

    # Generate the libgraphic_utils.so file in the out directory of the product folder through GN compilation.
    hb build graphic_utils_lite

    Description

    Usage

    • Utils is used in UI, surface, and WMS modules. For details, see the related source code.
    • The test folder provides unit testing for each utils API. Refer to it for the usage of utils.
