Tessellation quality options

Fields

feathering: bool

Use “feathering” to smooth out the edges of shapes as a form of anti-aliasing.

Feathering works by making each edge into a thin gradient into transparency. The size of this edge is controlled by Self::feathering_size_in_pixels.

This makes shapes appear smoother, but requires more triangles and is therefore slower.

This setting does not affect text.

Default: true.

feathering_size_in_pixels: f32

The size of the feathering, in physical pixels.

The default, and suggested, value for this is 1.0. If you use a larger value, edges will appear blurry.

coarse_tessellation_culling: bool

If true (default) cull certain primitives before tessellating them. This likely makes

prerasterized_discs: bool

If true, small filled circled will be optimized by using pre-rasterized circled from the font atlas.

round_text_to_pixels: bool

If true (default) align text to the physical pixel grid. This makes the text sharper on most platforms.

round_line_segments_to_pixels: bool

If true (default), align right-angled line segments to the physical pixel grid.

This makes the line segments appear crisp on any display.

round_rects_to_pixels: bool

If true (default), align rectangles to the physical pixel grid.

This makes the rectangle strokes more crisp, and makes filled rectangles tile perfectly (without feathering).

You can override this with crate::RectShape::round_to_pixels.

debug_paint_clip_rects: bool

Output the clip rectangles to be painted.

debug_paint_text_rects: bool

Output the text-containing rectangles.

debug_ignore_clip_rects: bool

If true, no clipping will be done.

bezier_tolerance: f32

The maximum distance between the original curve and the flattened curve.

epsilon: f32

The default value will be 1.0e-5, it will be used during float compare.

parallel_tessellation: bool

If rayon feature is activated, should we parallelize tessellation?

validate_meshes: bool

If true, invalid meshes will be silently ignored. If false, invalid meshes will cause a panic.

The default is false to save performance.

Trait Implementations

impl Clone for TessellationOptions

fn clone(&self) -> TessellationOptions

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TessellationOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for TessellationOptions

fn default() -> TessellationOptions

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TessellationOptions

where TessellationOptions: Default,

fn deserialize<__D>( __deserializer: __D, ) -> Result<TessellationOptions, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TessellationOptions

fn eq(&self, other: &TessellationOptions) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for TessellationOptions

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Widget for &mut TessellationOptions

fn ui(self, ui: &mut Ui) -> Response

Allocate space, interact, paint, and return a Response.

impl Copy for TessellationOptions

impl StructuralPartialEq for TessellationOptions
