Dim instance As IBarcodeReadOptions Dim value As RasterColor instance.BackColor = value value = instance.BackColor
[DescriptionAttribute("Background (space) color to use when searching for barcodes")] [DisplayNameAttribute("Background color")] [CategoryAttribute(" Colors")] RasterColor BackColor {get; set;}

If the input image is bitonal (B/W), then this value will not be used. The foreground color is always considered to be black (or the foreground color in the image palette) and the background color is always considered to be white (or the background color in the image palette).
When the input image is not bitonal, LEADTOOLS will perform an intensity detect operation on the image to convert it to black and white before searching for the barcodes and uses the value of ForeColor and BackColor as the high and low threshold.
For an example, refer to ForeColor.
