struct

This is a value type that represents a point in a 2D coordinate system. It uses reals to define the X and Y coordinates of that point (c.f. Point ).

As with Point , a PointF {0.0, 0.0} is located at the center of the pixel (0,0). However, if you specify a point at {0.5, 0.5} and draw a single pixel at that location, the rendering engine must resolve that into something it can draw on the device's pixel array, as it will impact at least 4 adjacent pixels in that grid. The method it uses to resolve that issue is determined by various properties of the Graphics object, including PixelOffsetMode , CompositingMode , and SmoothingMode .

There are comparison operators between PointF objects, and addition and subtraction operators for Size objects (but not SizeF objects, curiously).

Conversions between PointF and Point are handled through methods and operators on the Point class.
