LinearBarCodeSymbology Class

public abstract class LinearBarCodeSymbology : BarCodeSymbology, DUCE.IResource, IAnimatable, IFrameworkInputElement, IInputElement, ISupportInitialize, IHaveResources, IQueryAmbient

protected LinearBarCodeSymbology()

protected string BarData { get; set; }

Property Value

String:

The string that specifies the data used to draw the bar code.

public double BarHeight { get; set; }

Property Value

Double:

The desired height of the bars. The default value is 35.

Remarks

When calculating the desired height of the bar code, the BarHeight property will be used unless its height is less than the percentage of the desired width specified by MinBarHeightWidthRatio. In that case the MinBarHeightWidthRatio percentage of the desired width is used for height. This ensures that the bar code is always sized to be read properly.

public double BarWidthRatio { get; set; }

Property Value

Double:

The width ratio of wide lines to narrow lines. The default value is 2, meaning that wide lines are twice as thick as narrow lines.

public string DisplayValue { get; protected set; }

Property Value

String:

The value that is displayed if ValueDisplayStyle is not None.

Remarks

This property must be set by each symbology implementation.

protected Dictionary<char, LinearBarCodeSymbologyInstruction> Instructions { get; set; }

Property Value

Dictionary<Char, LinearBarCodeSymbologyInstruction>:

The dictionary of BarData characters and their related instructions.

public double MinBarHeightWidthRatio { get; set; }

Property Value

Double:

The minimum ratio that the height of the bar code must be in relation to its width. The default value is 0.15 (15%).

Remarks

Many symbologies indicate that the bar code's height must be at least x% of its width. For instance, Code 39 specifies that the height must be at least 15% of the width.

When calculating the desired height of the bar code, the BarHeight property will be used unless its height is less than the percentage of the desired width specified by MinBarHeightWidthRatio. In that case the MinBarHeightWidthRatio percentage of the desired width is used for height. This ensures that the bar code is always sized to be read properly.

public Thickness QuietZoneThickness { get; set; }

Property Value

Thickness:

The Thickness of the quiet zone. The default value is 10,0,10,0.

Remarks

The quiet zone is the margin whitespace area that appears around the bar code.

public LinearBarCodeValueDisplayStyle ValueDisplayStyle { get; set; }

Property Value

LinearBarCodeValueDisplayStyle:

A LinearBarCodeValueDisplayStyle that indicates how the value should rendered. The default value is Centered.

public double ValueIntrusionOffset { get; set; }

Property Value

Double:

The distance that the Value text intrudes into the bar code when ValueDisplayStyle is not None. The default value is 0.

protected override Size MeasureOverride(Size availableSize)

Parameter	Type	Description
availableSize	Size	The available size that this element can give to child elements. Infinity can be specified as a value to indicate that the element will size to whatever content is available.

Returns

Size:

The size that this element determines it needs during layout, based on its calculations of child element sizes.

public override void Render(DrawingContext drawingContext, Point location, Size size)

Parameter	Type	Description
drawingContext	DrawingContext	The DrawingContext upon which to render the symbology.
location	Point	The location at which to draw the bar code.
size	Size	The size of the bar code to draw.
