[−][src]Struct qt_3d_render::QDithering

#[repr(C)]pub struct QDithering { /* fields omitted */ }

Enable dithering

C++ class: Qt3DRender::QDithering.

C++ documentation:

Enable dithering

A Qt3DRender::QDithering class enables dithering. Dithering adds noise to the color values to randomize quantization error in order to prevent large scale patterns in the final image, such as banding. Dithering is most useful when rendering to a surface with low color bit depth, such as RGB565 or RGBA4444.

Methods

impl QDithering[src]

pub unsafe fn meta_object(&self) -> Ptr<QMetaObject>[src]

Calls C++ function: virtual const QMetaObject* Qt3DRender::QDithering::metaObject() const.

pub unsafe fn new_1a(parent: impl CastInto<Ptr<QNode>>) -> QBox<QDithering>[src]

Default constructs an instance of QDithering.

Calls C++ function: [constructor] void Qt3DRender::QDithering::QDithering(Qt3DCore::QNode* parent = …).
