ForeColor Property

Summary
Gets or sets the barcode foreground (bars or symbol) color used when writing barcodes.
Syntax
C#
Objective-C
C++
Java
public RasterColor ForeColor { get; set; } 
@property (nonatomic, copy) LTRasterColor *foreColor; 
public RasterColor getForeColor() 
public void setForeColor(RasterColor value) 
public: 
property RasterColor ForeColor { 
   RasterColor get(); 
   void set (    RasterColor ); 
} 

Property Value

A RasterColor that specifies the barcode foreground (bars or symbol) color when writing barcodes. Default value is "Black" (RGB of #000000). The default value is #FF000000.

Remarks

LEADTOOLS will use ForeColor and BackColor when drawing the new barcode to the image and no special processing is performed. Note that you can specify a transparent color for BackColor to "overlay" the barcode on top of the background of the image. This however, is not recommended.

Example

This example writes a UPC-A barcode to an image with specific colors.

C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Barcode; 
using Leadtools.ImageProcessing; 
 
 
public void BarcodeWriteOptions_ColorsExample() 
{ 
	string imageFileName = Path.Combine(LEAD_VARS.ImagesDir, "MyBarcode.png"); 
 
	BarcodeEngine engine = new BarcodeEngine(); 
	BarcodeWriter writer = engine.Writer; 
 
	// We will create a Red over Yellow backround 
	RasterColor foreColor = RasterColor.FromKnownColor(RasterKnownColor.Red); 
	RasterColor backColor = RasterColor.FromKnownColor(RasterKnownColor.Yellow); 
 
	// Create a UPC-A barcode 
	BarcodeData barcode = BarcodeData.CreateDefaultBarcodeData(BarcodeSymbology.UPCA); 
	barcode.Bounds = new LeadRect(0, 0, 400, 200); 
 
	// Create a 24 BPP image the same size as the barcode 
	// The image will have red over yellow colors 
	int resolution = 300; 
	LeadRect pixels = barcode.Bounds; 
	using (RasterImage image = RasterImage.Create(pixels.Width, pixels.Height, 24, resolution, backColor)) 
	{ 
		// Change the barcode colors to be Red over Yellow 
		OneDBarcodeWriteOptions options = writer.GetDefaultOptions(BarcodeSymbology.UPCA) as OneDBarcodeWriteOptions; 
		options.ForeColor = foreColor; 
		options.BackColor = backColor; 
 
		// Write the barcode 
		writer.WriteBarcode(image, barcode, options); 
 
		// Save as PNG 
		using (RasterCodecs codecs = new RasterCodecs()) 
		{ 
			codecs.Save(image, imageFileName, RasterImageFormat.Png, 24); 
		} 
	} 
}
