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 mesh grid. This makes the text sharper on most platforms.

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

Formats the value using the given formatter.

impl Default for TessellationOptions

fn default() -> Self

Returns the “default value” for a type.

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.
