Constructors
Grid2DBarCodeSymbology()
protected Grid2DBarCodeSymbology()Properties
CellSize
Gets or sets the number of pixels wide and high that each cell of the symbol grid should be when rendered. This is a dependency property.
public int CellSize { get; set; }Property Value
- System.Int32:
The size of the cell.
GridData
Gets or sets an two dimensional array of boolean values that specifies how the symbol is to be rendered.
protected bool[, ] GridData { get; set; }Property Value
- System.Boolean[,]:
The grid data.
QuietZoneThickness
Gets or sets the thickness of the margin on each side of the rendered symbol. This is a dependency property.
public Thickness QuietZoneThickness { get; set; }Property Value
- System.Windows.Thickness:
The quiet zone.
Methods
MeasureOverride(Size)
When overridden in a derived class, measures the size in layout required for child elements and determines a size for the System.Windows.FrameworkElement-derived class.
protected override Size MeasureOverride(Size availableSize)| Parameter | Type | Description |
|---|---|---|
| availableSize | System.Windows.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
- System.Windows.Size:
The size that this element determines it needs during layout, based on its calculations of child element sizes.
Render(DrawingContext, Point, Size)
Renders the symbology to the specified System.Windows.Media.DrawingContext.
public override void Render(DrawingContext drawingContext, Point location, Size size)| Parameter | Type | Description |
|---|---|---|
| drawingContext | System.Windows.Media.DrawingContext | The System.Windows.Media.DrawingContext upon which to render the symbology. |
| location | System.Windows.Point | The location at which to draw the bar code. |
| size | System.Windows.Size | The size of the bar code to draw. |
