Class QrLogo

Represents a logo to be embedded within a QR code.

Inheritance
System.Object
QrLogo
Namespace: IronQr
Assembly: IronQr.dll
Syntax
public sealed class QrLogo : ValueType

An image embedded in the center of a QR code is described by QrLogo. It is assigned to QrStyleOptions.Logo, so a brand mark is placed on the code at the moment it is saved. Build one from the logo image and its target size.

The constructor takes an AnyBitmap plus a width, height, and cornerRadius, and the Bitmap, Width, Height, and CornerRadius properties expose the same values. Width and Height size the logo within the code, and CornerRadius rounds its corners for a softer placement. Because a logo covers part of the symbol, raise the QrErrorCorrectionLevel on the QrOptions used to write the code so it still scans reliably, and keep the logo small relative to the code's Dimensions. A rounded, modestly sized mark reads as deliberate branding while leaving enough of the pattern intact for dependable scanning.

style.Logo = new QrLogo(logoBitmap, 80, 80);

The custom logo how-to embeds a logo, and the styled QR example shows it within a full style.
