public class hb_feature_t extends org.lwjgl.system.Struct<hb_feature_t> implements org.lwjgl.system.NativeResource
The structure that holds information about requested feature application.

The feature will be applied with the given value to all glyphs which are in clusters between start (inclusive) and end (exclusive). Setting start to FEATURE_GLOBAL_START and end to FEATURE_GLOBAL_END specifies that the feature always applies to the entire buffer.

    • hb_feature_t

      public hb_feature_t(ByteBuffer container)
      Creates a hb_feature_t instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

      The created instance holds a strong reference to the container object.

  • Method Details

    • sizeof

      public int sizeof()
