Name
PointF
Synopsis
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.
