PolylineRef

Points live in a registered asset, so a path of any length costs one record.

Fields

§paint: Paint

§asset_id: u32

§stroke_width: f32

TextAt

The text bytes follow the command array inside the same list, and the offset is measured from the start of that list, so the list decodes on its own.

Fields

§paint: Paint

§text_offset: u32

§text_length: u32

§x: f32

§y: f32

§type_role: TypeRole
