Tessellation quality options

Fields

pixels_per_point: f32

Size of a point in pixels (DPI scaling), e.g. 2.0. Used to snap text to pixel boundaries.

aa_size: f32

The size of a pixel (in points), used for anti-aliasing (smoothing of edges). This is normally the inverse of Self::pixels_per_point, but you can make it larger if you want more blurry edges.

anti_alias: bool

Anti-aliasing makes shapes appear smoother, but requires more triangles and is therefore slower. This setting does not affect text. Default: true.

coarse_tessellation_culling: bool

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

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.
