public bool AutoSize { get; set; }

Public Property AutoSize As Boolean

Property Value

Type	Description
Boolean

true , to create an image unrestricted to the specified size; otherwise, false.

Remarks

If the AutoSize is set to true , the BarCode.ImageWidth and BarCode.ImageHeight are not taken into account when an image is generated. You can get the image in a size that satisfies all the specified options.

If you set the AutoSize to false , the image will be clipped to the specified size. In this situation, you have to adjust the options which affect the image size (BarCode.Dpi, BarCode.TopCaption, BarCode.BottomCaption etc.) manually to achieve the desired size.

The code sample below creates a QR code and displays it in a PictureBox.

C#
VB.NET

csharp

using DevExpress.BarCodes;
//...
this.pictureBox1.Image = null;

BarCode barCode = new BarCode();
barCode.Symbology = Symbology.QRCode;
barCode.CodeText = "https://www.devexpress.com/";
barCode.BackColor = Color.White;
barCode.ForeColor = Color.Black;
barCode.RotationAngle = 0;
barCode.CodeBinaryData = Encoding.Default.GetBytes(barCode.CodeText);
barCode.Options.QRCode.CompactionMode = QRCodeCompactionMode.Byte;
barCode.Options.QRCode.ErrorLevel = QRCodeErrorLevel.Q;
barCode.Options.QRCode.ShowCodeText = false;
barCode.AutoSize = true;

this.pictureBox1.Image = barCode.BarCodeImage;
pictureBox1.Size = pictureBox1.Image.Size;

Imports DevExpress.BarCodes

Dim barCode As New BarCode()
