    Image Options

    Barcode Xpress works with 1-bit black and white images, 8-bit grayscale images, and 24-bit color images.

    Barcode Xpress for .NET Core should process images in any format that can be loaded into a System.Drawing.Bitmap, such as GIF, JPEG, EXIF, TIF, and PNG.

    On Linux, BMPs of version 4 and higher are only supported when libgdiplus 6.0.1 or higher is installed on the system.

    C#

    using (Bitmap bitmap = new Bitmap(imagePath))
    {
        // Get barcode results by passing in Bitmap object.
        Result[] results = barcodeXpress.reader.Analyze(bitmap);
    }
    

    Setting Barcode Type

    Set the barcode type by using the BarcodeTypes property.

    C#

    using (Bitmap bitmap = new Bitmap(imagePath))
    {
        // Get barcode results by passing in a Bitmap object.
        barcodeXpress.reader.BarcodeTypes = new BarcodeType[] { 
        BarcodeType.QRCodeBarcode, BarcodeType.PDF417Barcode };
        Result[] results = barcodeXpress.reader.Analyze(bitmap);
    }
    

    Use the BarcodeType enum to set the BarcodeType array. See the Barcode Types page for more information and examples of each supported barcode type.
