LinearBarCodeSymbology Class

public abstract class LinearBarCodeSymbology : BarCodeSymbology

protected LinearBarCodeSymbology()

protected string? BarData { get; set; }

Property Value

string

public double BarHeight { get; set; }

Property Value

double:

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 default value is 2, meaning that wide lines are twice as thick as narrow lines.

public string? DisplayValue { get; protected set; }

Property Value

string

Remarks

This property must be set by each symbology implementation.

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

Property Value

Dictionary<char, LinearBarCodeSymbologyInstruction>

public double MinBarHeightWidthRatio { get; set; }

Property Value

double:

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 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:

The default value is Centered.

public double ValueIntrusionOffset { get; set; }

Property Value

double

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.
