public abstract class Grid2DBarCodeSymbology : BarCodeSymbology- Inheritance:
- object Visual UIElement FrameworkElement BarCodeSymbology object
- Derived:
- QrCodeSymbology
Constructors
Grid2DBarCodeSymbology()
Initializes an instance of the class.
protected Grid2DBarCodeSymbology()Properties
CellSize
The number of pixels wide and high that each cell of the symbol grid should be when rendered.
GridData
A two dimensional array of boolean values that specifies how the symbol is to be rendered.
QuietZoneThickness
The thickness of the margin on each side of the rendered symbol.
Methods
MeasureOverride(Size)
When overridden in a derived class, measures the size in layout required for child elements and determines a size for the FrameworkElement-derived class.
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.
Render(DrawingContext, Point, Size)
Renders the symbology to the specified DrawingContext.
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. |
