Where does Point live in the IronDrawing API?

Point is a class in the IronSoftware.Drawing namespace, shipped in IronSoftware.Drawing.dll. It derives from Object and is constructed with new Point(int x, int y). It is not an interface or struct, so X and Y are settable properties on the instance.

How do you shift a Point's position without creating a new instance?

Call Offset(int dx, int dy) on the existing Point. It adds dx to X and dy to Y in place, so no replacement object is needed. This is useful when adjusting coordinates returned from a detection or layout step.

What types does Point convert to and from implicitly?

Point defines implicit operators to and from System.Drawing.Point and SKPointI, among other supported coordinate types. Assignments and method arguments that expect those types accept a Point directly, and the reverse conversions are also defined, so no explicit cast is required.

Is Point safe to use as a dictionary key or in a hash set?

Yes. Point overrides both Equals and GetHashCode to compare by coordinate value rather than by reference, so two Point instances with the same X and Y are considered equal and produce the same hash code.

Class Point

Represents an ordered pair of double x- and y-coordinates that defines a point in a two-dimensional plane.

Inheritance

System.Object

Point

Namespace: IronSoftware.Drawing

Assembly: IronSoftware.Drawing.Common.dll

Syntax

public class Point : Object

Pixel-precise coordinate work in C# gets a cross-library anchor through Point, a lightweight record that holds an integer X and Y pair representing a location in a two-dimensional plane. Because IronDrawing targets cross-platform compatibility, Point ships with a full set of implicit conversion operators so the same value flows into SkiaSharp (SKPointI), System.Drawing (System.Drawing.Point), and other coordinate types without explicit casting.

Construct a value with new Point(int x, int y). The two settable properties, X and Y, expose the horizontal and vertical components directly and can be reassigned after construction. When you need to shift a point relative to its current position, Offset(int dx, int dy) adds the deltas in place, which is cleaner than constructing a replacement. Equals and GetHashCode are overridden so Point values compare by coordinate rather than by reference, making them safe to use in dictionaries and hash sets.

The implicit operators are the feature that earns Point its role as a hub type. Assignments and method arguments that expect a System.Drawing.Point, a SKPointI, or one of the other supported coordinate types accept a Point directly, and the reverse conversions are also defined. This means code that mixes IronDrawing with SkiaSharp or with System.Drawing does not need adapter layers or manual unpacking.

A common pattern is to read coordinates from a cropping rectangle or a detected region, adjust them with Offset, and then pass the result straight to a rendering or layout API that expects a different point type:

using IronSoftware.Drawing;

var origin = new Point(120, 80);
origin.Offset(10, -5);

// Implicit conversion: no cast needed when the target API expects SKPointI
SKPointI skPoint = origin;
Console.WriteLine($"SKPointI: {skPoint.X}, {skPoint.Y}");

The IronDrawing get-started guide covers installation and setup. The coordinate types overview explains how Point, Rectangle, and Color relate to each other. For practical usage patterns, the cross-library interop examples show implicit conversions in action.
