一. 如何創(chuàng)建針對(duì)Thermal Printers（熱敏打印機(jī)）優(yōu)化的位圖？

VB .NET中的以下示例代碼生成針對(duì)熱敏打印機(jī)輸出（分辨率如203 dpi）優(yōu)化的條形碼圖像：

Dim bc As New TECIT.TBarCode.Barcode()

bc.BarcodeType = TECIT.TBarCode.BarcodeType.EanUcc128
bc.Data = "1234567890123"

' set font size
bc.Font = New System.Drawing.Font("Arial", 15, System.Drawing.FontStyle.Bold, GraphicsUnit.Point)

bc.TextDistance = 1.1

bc.BearerBarType = TECIT.TBarCode.BearerBarType.TopAndBottom
bc.BearerBarWidth = 2.4

' adjust quiet zone in [Modules] (recommended for bitmaps)
bc.QuietZoneUnit = TECIT.TBarCode.QuietZoneUnit.Modules
bc.QuietZoneLeft = 12
bc.QuietZoneRight = 12

' important: set printer resolution of thermal printer
bc.Dpi = 203

' 203 dpi --> Module Width = 0.5005 = 4 Pixel per Module
Dim moduleWidth As New Single
moduleWidth = 0.5004926  'need exact value here!

bc.SizeMode = TECIT.TBarCode.SizeMode.CustomModuleWidth
bc.ModuleWidth = moduleWidth + 0.001
bc.AdjustModuleWidthToPixelRaster = True

Dim width As New Single
Dim height As New Single

' size in [mm]
width = bc.CalculateBarcodeWidth(Nothing)
height = 35

' convert size to [Pixels]
width = width / (25.4 / bc.Dpi)
height = height / (25.4 / bc.Dpi)

' adjust bitmap size
Dim drawBitmapRect As New Rectangle(0, 0, width, height)
bc.BoundingRectangle = drawBitmapRect

' output to file
bc.Draw("barcode.bmp", TECIT.TBarCode.ImageType.Bmp)

二. 如何創(chuàng)建具有恒定大小的可讀PDF417位圖？

C＃ASP .NET中的以下示例代碼生成具有恒定大小的PDF417圖像：

//PDF417
Barcode barcode = new Barcode();
barcode.Data = strMyData;
barcode.BarcodeType = BarcodeType.Pdf417;
barcode.Pdf417.EncodingMode = PdfEncodingMode.Binary;

// with dpi = 100 we get 1 Pixel = 0.254 mms
barcode.Dpi = 100;

 // we should specify the number of horizontal data columns
 // this inhibits the symbol to change its horizontal size regardless of data
 barcode.Pdf417.NumberOfColumns = 16; // use a value, which fits to your available space !!

 // now calculate optimal bitmap size for the bar code
 barcode.SizeMode = SizeMode.FitToBoundingRectangle;
 Size optimalSize = barcode.CalculateOptimalBitmapSize(null, 1, 1);

 // we already could use this optimal Size for saving the image
 // barcode.BoundingRectangle = new Rectangle(0, 0, optimalSize.Width,  optimalSize.Height);
 // barcode.Draw(filename, ImageType.Jpg);

 // but we want a constant bitmap size,
 // which fits exactly into your predefined space

 Size finalSize = new Size(350, 200); // final bitmap size in Pixel

 // so we have to add empty spaces around the symbol via adding a quiet zone
 barcode.QuietZoneUnit = QuietZoneUnit.Pixel;

 // calculate the required empty quiet zone we have to add

if (finalSize.Width > optimalSize.Width)
  barcode.QuietZoneRight = finalSize.Width - optimalSize.Width;
else
  // should not occur!! Reduce the Pdf417.NumberOfColumns
  finalSize.Width = optimalSize.Width;
            
if (finalSize.Height > optimalSize.Height)
  barcode.QuietZoneBottom = finalSize.Height - optimalSize.Height;
else
  // should not occur!! Increase final bitmap size
  finalSize.Height = optimalSize.Height;

barcode.BoundingRectangle = new Rectangle(0, 0, finalSize.Width, finalSize.Height);
barcode.Draw(filename, ImageType.Jpg);

三. 如何在ASP.NET Web控件中優(yōu)化PDF417符號(hào)？

選項(xiàng)1

將以下屬性添加到TBarCode .NET Web Control。這將生成一個(gè)優(yōu)化的符號(hào)，適合120 x 120像素矩陣。如果需要，請(qǐng)?jiān)黾?“寬度/高度”和“NumberOfColumns”屬性。

<cc2：BarcodeControl id =“BarcodeControl1” 
  Width =“120”Height =“120” 
  Barcode-Dpi =“96” 
  Barcode-SizeMode =“MinimalModuleWidth” 
  Barcode-Pdf417-NumberOfColumns =“3”                         
  Barcode-MustFit =“True”ErrorHandling =“ShowMessage” 
  Barcode-BarcodeType =“Pdf417”

選項(xiàng)＃2

在頁(yè)面加載事件中或設(shè)置條形碼數(shù)據(jù)后，應(yīng)用以下計(jì)算。此代碼將使用1：3的寬高比為圖形模塊。

Barcode barcode = BarcodeControl1.Barcode;
barcode.SizeMode = SizeMode.FitToBoundingRectangle;  
System.Drawing.Size optimalSize = barcode.CalculateOptimalBitmapSize(null, 1, 1);

BarcodeControl1.Width = new Unit(optimalSize.Width, UnitType.Pixel);
BarcodeControl1.Height = new Unit(optimalSize.Height, UnitType.Pixel);  

BarcodeControl1.Refresh();

四. 如何創(chuàng)建可讀代碼39位圖？

ASP .NET中的以下示例代碼生成Code 39圖像：

//Code 39
Barcode barcode = new Barcode();
barcode.Data = "10030000007611107871900002199908";
barcode.BarcodeType = BarcodeType.Code39;

// with dpi = 100 we get 1 Pixel = 0.254 mms
barcode.Dpi = 100;

// bar code size should adapt to bounding rectangle
barcode.SizeMode = SizeMode.FitToBoundingRectangle;

// set default size of symbol (define the default height)
barcode.BoundingRectangle = new Rectangle(0, 0, 254, 100 /* = 1 inch */);
                
// now calculate optimal bitmap size for the bar code
Size optimalSize = barcode.CalculateOptimalBitmapSize(null, 1, 1);

// update rectangle to optimized size
barcode.BoundingRectangle  = new Rectangle(0, 0, optimalSize.Width, optimalSize.Height);
barcode.Draw(filename, ImageType.Jpg);

五. 如何為DP Premiumadress創(chuàng)建26x26數(shù)據(jù)矩陣？

以下C＃.NET示例代碼向您展示了如何調(diào)整Data Matrix的設(shè)置：

Barcode barcode = new TECIT.TBarCode.Barcode();
      
barcode.BarcodeType = BarcodeType.DataMatrix;
barcode.DataMatrix.Size = DataMatrixSize.Square26x26;
barcode.DataMatrix.Format = DataMatrixFormat.Default;
barcode.DataMatrix.ShallEnforceBinaryEncoding = true;

barcode.SizeMode = SizeMode.CustomModuleWidth;
barcode.ModuleWidth = 0.423;

barcode.EncodingMode = EncodingMode.Hexadecimal;
// set preformatted data (Bytes = Hex codes)
barcode.Data = "444541080D02540BE3FF0052232D242D000065000000010100015A313031000000000000000000000000";
