ForeColor Property

Gets or sets the barcode foreground (bars or symbol) color used when writing barcodes.
public RasterColor ForeColor { get; set; } 
@property (nonatomic, copy) LTRasterColor *foreColor; 
public RasterColor getForeColor() 
public void setForeColor(RasterColor value) 
property RasterColor ForeColor { 
   RasterColor get(); 
   void set (    RasterColor ); 
ForeColor # get and set (BarcodeWriteOptions) 

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.


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.


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