在 QR 碼中加入標誌，可將標準圖案轉化為品牌資產。企業會在行銷素材、產品包裝及數位行銷活動中使用嵌入商標的 QR 碼，藉此強化品牌辨識度，同時確保 QR 碼具備完整的可掃描性。

IronQR 支援透過 QrLogo 類別及 Logo 屬性，在 QrStyleOptions 中嵌入標誌。 QrLogo 建構函式接受寬度、高度和圓角半徑等參數，讓您能自由控制標誌的呈現樣式。

在本指南中，我們將向您展示如何使用 C# 中的 IronQR 將標誌嵌入 QR 碼中。

快速入門：為 QR 碼添加標誌

載入標誌圖像，將其附加至 QrStyleOptions，並儲存帶有品牌標誌的 QR 碼。

使用NuGet套件管理器安裝https://www.nuget.org/packages/IronQR
PM > Install-Package IronQR

複製並運行這段程式碼。

var qrCode = QrWriter.Write("https://example.com");
var logo = new QrLogo(AnyBitmap.FromFile("logo.png"), 50, 50, 5);
var style = new QrStyleOptions { Logo = logo };
qrCode.Save(style).SaveAs("qr-with-logo.png");

部署到您的生產環境進行測試

今天就在您的專案中開始使用免費試用IronQR

最小工作流程（5 個步驟）

下載 C# 函式庫，以建立內嵌標誌的 QR 碼
使用 `AnyBitmap.FromFile` 載入您的標誌圖片
建立一個具有尺寸和圓角參數的 `QrLogo`
透過 `Logo` 屬性設定 `QrStyleOptions`
使用"`另存為"`功能儲存品牌 QR 碼

將標誌嵌入 QR 碼

若要新增標誌，請使用 AnyBitmap.FromFile 載入您的圖片，然後建立一個 QrLogo 物件，並指定寬度、高度及圓角半徑。將其指派給 Logo 中的 QrStyleOptions 屬性。

為獲得最佳效果，請使用透明或白色背景的方形標誌。 "邊角半徑"參數可讓您將標誌邊緣進行圓角處理，呈現更精緻的外觀。

:path=/static-assets/qr/content-code-examples/how-to/add-custom-logo-qr-code.cs

using IronQr;
using IronSoftware.Drawing;

// Load new logo image
AnyBitmap logo = AnyBitmap.FromFile("sample.png");

// Add new logo to QR code style options
QrStyleOptions styleOptions = new QrStyleOptions()
{
    Logo = new QrLogo(logo, 0, 0, 10),
    Dimensions = 500,
};

// Create QR code with URL data
QrCode qr = QrWriter.Write("https://ironsoftware.com/csharp/qr/");

// Save QR code as a bitmap
AnyBitmap qrImage = qr.Save(styleOptions);

// Save QR code bitmap as file
qrImage.SaveAs("qrURLWithLogo.png");

Imports IronQr
Imports IronSoftware.Drawing

' Load new logo image
Dim logo As AnyBitmap = AnyBitmap.FromFile("sample.png")

' Add new logo to QR code style options
Dim styleOptions As New QrStyleOptions() With {
    .Logo = New QrLogo(logo, 0, 0, 10),
    .Dimensions = 500
}

' Create QR code with URL data
Dim qr As QrCode = QrWriter.Write("https://ironsoftware.com/csharp/qr/")

' Save QR code as a bitmap
Dim qrImage As AnyBitmap = qr.Save(styleOptions)

' Save QR code bitmap as file
qrImage.SaveAs("qrURLWithLogo.png")

$vbLabelText $csharpLabel

輸出

接下來是什麼？

當您的標誌定位妥當後，請考慮調整 QR 碼的顏色以符合您的品牌色系，增加邊距以確保在較小尺寸下仍能清晰掃描，或設定錯誤校正等級，以確保在疊加較大標誌時，QR 碼仍能保持可讀性。
