<DescriptionAttribute("Barcode reader inverts the image with barcodes before barcode search.")>
<DefaultValueAttribute(False)>
Public Property InvertImageColors As Boolean

[Description("Barcode reader inverts the image with barcodes before barcode search.")]
[DefaultValue(False)]
public bool InvertImageColors { get; set; }

[Description("Barcode reader inverts the image with barcodes before barcode search.")]
[DefaultValue(False)]
public: __property bool get_InvertImageColors();
public: __property void set_InvertImageColors(
   bool value
);

[Description("Barcode reader inverts the image with barcodes before barcode search.")]
[DefaultValue(False)]
public:
property bool InvertImageColors {
   bool get();
   void set(bool value);
}

Property Value

false - pixel with index 0 in color table will be interpreted as black pixel, pixel with index 1 in color table will be interpreted as white pixel,
true - pixel with index 0 in color table will be interpreted as white pixel, pixel with index 1 in color table will be interpreted as black pixel.
Default value is false.

Remarks

.NET Framework loads color table from some TIFF files uncorrectly and as a result images will be inverted. This property must be set to true for solving this problem and correct barcode reading.

Requirements

Target Platforms: .NET 10; .NET 9; .NET 8; .NET 7; .NET 6; .NET Framework 4.8, 4.7, 4.6, 4.5, 4.0, 3.5
