Method: IEnumerable<Vertex> Vertices(int, int, int, int)

• Declared in: RT.Coordinates.Cairo

Declaration

public IEnumerable<Vertex> Vertices(
    int dx,
    int dy,
    int dw,
    int dh
)

Summary

Returns the vertices along the perimeter of this Cairo assuming that we’re rendering a rectangle positioned at (dx/2, dy/2) and of size dw/2 × dh/2 and we want the edges of the rectangle straightened.

Parameters

int	dx	Double the x-coordinate of the top-left corner of the rectangle.
int	dy	Double the y-coordinate of the top-left corner of the rectangle.
int	dw	Double the width of the rectangle.
int	dh	Double the height of the rectangle.

Remarks

The reason the arguments are all doubled is because a single integer coordinate pair refers to four cairos (arranged in a 2×2). By using doubled values, we effectively support half-integer points and sizes.
