Struct GeometryBuilder 

pub struct GeometryBuilder;

Contains internal helpers used to build and draw various geometries.

Implementations

impl GeometryBuilder

pub fn draw_rounded_corners_rectangle_keypoints( context: &mut StreamGeometryContext, keypoints: &RoundedRectKeypoints, )

Draws a new rounded rectangle within the given geometry context. Warning: The caller must manage and dispose the StreamGeometryContext externally.

WinUI: https://github.com/microsoft/microsoft-ui-xaml/blob/93742a178db8f625ba9299f62c21f656e0b195ad/dxaml/xcp/core/core/elements/geometry.cpp#L1072-L1079

• context - The geometry context to draw into.
• keypoints - The rounded rectangle keypoints defining the rectangle to draw.

pub fn draw_rounded_corners_rectangle( context: &mut dyn IGeometryContext, rect: Rect, radius_x: f64, radius_y: f64, )

Draws a new rounded rectangle within the given geometry context. Warning: The caller must manage and dispose the StreamGeometryContext externally.

• context - The geometry context to draw into.
• rect - The existing rectangle dimensions without corner radii.
• radius_x - The radius on the X-axis used to round the corners of the rectangle.
• radius_y - The radius on the Y-axis used to round the corners of the rectangle.

pub fn calculate_rounded_corners_rectangle_win_ui( outer_bounds: Rect, border_thickness: Thickness, corner_radius: CornerRadius, sizing: BackgroundSizing, ) -> RoundedRectKeypoints

Calculates the keypoints of a rounded rectangle based on the algorithm in WinUI. These keypoints may then be drawn or transformed into other types.

• outer_bounds - The outer bounds of the rounded rectangle. This should be the overall bounds and size of the shape/control without any corner radii or border thickness adjustments.
• border_thickness - The unadjusted border thickness of the rounded rectangle.
• corner_radius - The unadjusted corner radii of the rounded rectangle. The corner radius is defined to be the middle of the border stroke (center of the border).
• sizing - The sizing mode used to calculate the final rounded rectangle size.

Returns new rounded rectangle keypoints.
