MeasureTextCore(String,GeoFont)

  • N/A
Remarks
  • This method is typically used for labeling to determine of labels overlap.
Return Value
  • Type:DrawingRectangleF

BeginDrawingCore(Object,RectangleShape,GeographyUnit)

  • N/A
Remarks
  • This is the first method that needs to be called before any drawing takes place. Calling this method will set the IsDrawing property to true. When you finish drawing you must call the EndDrawing to commit the changes to the image.
Return Value
  • Type:Void
  • Description:N/A
Parameters
  • nativeImage
    • Type:Object
    • Description:N/A
  • worldExtent
    • Type:RectangleShape
    • Description:This parameter is the world extent of the canvasImage.

EndDrawingCore()

  • N/A
Remarks
  • This methods should be called when you are finished drawing. It will commit the image changes to the image you passed in on the BeginDrawing. It will also set the 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.
Return Value
  • Type:Void
  • Description:N/A
Parameters

ToNativeImageCore(GeoImage)

  • N/A
Remarks
  • It is faster to provide a native image object to the canvas for drawing. In some cases you may not know what the native image type is. For example for GDI+ it is a bitmap class but dot GDI it may be a handle to a HBitmap. If you are not sure how to create the native image object you should first create a GeoImage and then call this method and it will pass you back the native image object. You can then use it to get excellent drawing performance in the GeoCanvas.
Return Value
  • Type:Object
  • Description:This method returns a native image object from a GeoCanvas passed in.
Parameters
  • image
    • Type:GeoImage
    • Description:This parameter is the GeoCanvas you want to convert to a native image.

ToGeoImageCore(Object)

  • N/A
Remarks
  • This method will allows you to convert your native image object to a GeoImage. Many times when you work with a GeoCanvas you may not know the format of the native image. Using this method you can always convert it back to a GeoImage which is a stream of a TIFF.
Return Value
  • Type:GeoImage
  • Description:This method returns a GeoImage from a native image object.
Parameters
  • nativeImage
    • Type:Object
    • Description:This parameter is the native image object you want to convert to a GeoImage.
