Class QrResultPosition

Represents the position of the detected QR code in the image.

Inheritance

System.Object

QrResultPosition

Namespace: IronQr

Assembly: IronQr.dll

Syntax

public sealed class QrResultPosition : ValueType

The location of a detected QR code within an image is given by QrResultPosition through its corner Points. When a read needs to do more than decode, for example draw a box around each code in a scanner UI or crop the region for review, the position tells the application where the code sits in the source pixels.

The Points property is a read-only PointF[] holding the corner coordinates of the detected symbol, and the constructor takes the same array. Map those points onto the displayed image to highlight or overlay the code. For the decoded text and type, read the QrResult itself, whose own Points property covers the common case; QrResultPosition is the focused value when position is passed or stored on its own.

PointF[] corners = position.Points;

The advanced read example works with detection detail, and the Blazor scanner example overlays results on a live view.
