labelDescriptor

fun labelDescriptor(init: LabelDescriptor.() -> Unit): LabelDescriptor

lineDescriptor

fun lineDescriptor(init: LineDescriptor.() -> Unit): LineDescriptor

rectangleDescriptor

fun rectangleDescriptor(init: RectangleDescriptor.() -> Unit): RectangleDescriptor

toArcDescriptor

fun CPointer<lv_draw_arc_dsc_t>?.toArcDescriptor(): ArcDescriptor

toDrawImageDescriptor

fun CPointer<lv_draw_img_dsc_t>?.toDrawImageDescriptor(): DrawImageDescriptor
