Class PointF
Represents an ordered pair of integer x- and y-coordinates that defines a point in a two-dimensional plane.
Inheritance
Namespace: IronSoftware.Drawing
Assembly: IronSoftware.Drawing.Common.dll
Syntax
public class PointF : ObjectPrecise sub-pixel positioning in cross-platform .NET graphics relies on PointF, a lightweight coordinate record that stores an ordered pair of single-precision floating-point values as X and Y. Wherever IronDrawing needs to express a location on a two-dimensional plane, such as a text anchor, a crop origin, or a shape vertex, PointF is the common currency that travels between rendering engines without losing fractional precision.
Construct a point with new PointF(float x, float y) and read or update its position through the X and Y properties, both of which are mutable. To shift a point relative to its current location, call Offset(float dx, float dy), which adds the supplied deltas directly to X and Y in place. This avoids allocating a replacement instance when only a translation is needed, which is common in layout loops that nudge elements by a fixed margin.
PointF integrates smoothly with SkiaSharp through a set of implicit conversion operators. An SKPoint converts to PointF automatically, and a PointF converts back to SKPoint, so code that mixes IronDrawing APIs with direct SkiaSharp calls requires no explicit casts. Additional implicit operators cover the System.Drawing.PointF type and related platform point types, meaning a value obtained from one graphics subsystem passes directly into another. Equals and GetHashCode are overridden so that PointF instances compare by coordinate value rather than reference, making them safe to use as dictionary keys or in LINQ distinct operations.
Because PointF derives from Object and carries no unmanaged resources, no disposal step is required. It is a plain, allocatable value-holder that fits naturally into collections, tuples, and return types throughout the IronDrawing surface.
using IronSoftware.Drawing;
// Build a point, shift it, then use it as an SKPoint implicitly.
var origin = new PointF(12.5f, 34.75f);
origin.Offset(5f, -10f); // origin is now (17.5, 24.75)
SkiaSharp.SKPoint skPt = origin; // implicit operator, no cast needed
Console.WriteLine($"SKPoint: {skPt.X}, {skPt.Y}");Explore further with the IronDrawing getting-started guide, the coordinate and geometry how-to, the AnyBitmap drawing examples, and the IronDrawing API documentation hub.
