D2D1_ROUNDED_RECT structure

Contains the dimensions and corner radii of a rounded rectangle.

Syntax

struct D2D1_ROUNDED_RECT {
  D2D1_RECT_F rect;
  FLOAT       radiusX;
  FLOAT       radiusY;
};

Members

rect

Type: D2D1_RECT_F

The coordinates of the rectangle.

radiusX

Type: FLOAT

The x-radius for the quarter ellipse that is drawn to replace every corner of the rectangle.

radiusY

Type: FLOAT

The y-radius for the quarter ellipse that is drawn to replace every corner of the rectangle.

Remarks

Each corner of the rectangle specified by the rect is replaced with a quarter ellipse, with a radius in each direction specified by radiusX and radiusY.

If the radiusX is greater than or equal to half the width of the rectangle, and the radiusY is greater than or equal to one-half the height, the rounded rectangle is an ellipse with the same width and height of the rect.

Even when both radiuX and radiusY are zero, the rounded rectangle is different from a rectangle., When stroked, the corners of the rounded rectangle are roundly joined, not mitered (square).
