EndDrawingCore()

• This method ends drawing and commits the drawing on the GeoCanvas.

• This methods should be called when you are finished drawing. It will commit the image changes to the image you passed in on BeginDrawing. It will also set IsDrawing to false. After you call this method it will put the GeoCanvas into an invalid state, so if you then call any drawing methods it will raise an exception.

• Type:Void
• Description:N/A

FlushCore()

• This method flush drawing and commits the drawing on the GeoCanvas.

• This method should be called when you are finished drawing. It will commit the image changes to the image you passed in on BeginDrawing. It will also set IsDrawing to false.

• Type:Double

DrawingQuality

This property returns the drawing quality when rendering on the GeoCanvas.

The DrawingQuality specifies whether BaseLineShapes, BasePointShapes, and BaseAreaShapes use anti-aliasing methods or other techniques that control the quality. In some cases you may want a higher quality rendering, and in other cases higher speed is more desirable. It is up to the implementer of the derived GeoCanvas class to control exactly what this setting means.

• Type:DrawingQuality

MapUnit

This property returns the MapUnit passed in on the BeginDrawingAPI in the GeoCanvas.

N/A

• Type:GeographyUnit

Width

This property gets the width of the canvas.

This property reflects the width of the canvas image that was passed in on BeginDrawing.

• Type:Single

Height

This property gets the height of the canvas.

This property reflects the height of the canvas image that was passed in on BeginDrawing.

• Type:Single

CurrentWorldExtent

This property gets the adjusted current extent based on what was set when BeginDrawing was called.

The extent that gets passed in on BeginDrawing is adjusted for the height and width of the physical media being drawn on. For example if the current extent is wider than taller but the bitmap being drawn on is square then the current extent needs to be adjusted. The extent will be adjusted larger so that we ensure that the entire original extent will still be represented.

• Type:RectangleShape

HasKeyColor

This property indicates whether a GeoCanvas has the KeyColor or not. If it has no KeyColor, it will throw an exception when you get or set the value of KeyColors property.

The default value is false.

• Type:Boolean

KeyColors

Gets a value represents a collection of key colors. If HasKeyColor property is false, it will throw exception when you use KeyColors.

It will make these colors transparent when draw image.
