GetImageWidthCore()

• N/A

• This abstract method is called from the concrete method GetImageWidth. You need to override it if you inherit from the RasterSource to return the width of your image. It returns the width of the image in screen coordinates.

• Type:Int32
• Description:This method returns the width of the image in screen coordinates.

GetImageHeightCore()

• N/A

• This abstract method is called from the concrete method GetImageHeight. You need to override it if you inherit from the RasterSource to return the height of your image. It returns the height of the image in screen coordinates.

• Type:Int32
• Description:This method returns the height of the image in screen coordinates.

GetBoundingBoxCore()

• N/A

• This method returns the bounding box of the RasterSource.

• Type:RectangleShape
• Description:This method returns the bounding box of the RasterSource.

OpenCore()

• N/A

• This protected virtual method is called from the concrete public method Open. The Open method plays an important role, as it is responsible for initializing the RasterSource. Most methods on the RasterSource will throw an exception if the state of the RasterSource is not opened. When the map draws each layer, it will open the RasterSource as one of its first steps; then, after it is finished drawing with that layer, it will close it. In this way, we are sure to release all resources used by the RasterSource. When implementing this abstract method, consider opening files for file-based sources, connecting to databases in the database-based sources and so on. You will get a chance to close these in the Close method of the RasterSource.

• Type:Void
• Description:N/A

CloseCore()

• N/A

• This protected virtual method is called from the concrete public method Close. The Close method plays an important role in the life cycle of the RasterSource. It may be called after drawing to release any memory and other resources that were allocated since the Open method was called. If you override this method, it is recommended that you take the following things into account: This method may be called multiple times, so we suggest you write the method so that that a call to a closed RasterSource is ignored and does not generate an error. We also suggest that in the Close you free all resources that have been opened. Remember that the object will not be destroyed, but will be re-opened possibly in the near future.

• Type:Void
• Description:N/A

GetImageCore(RectangleShape,Int32,Int32)

• N/A

• This method is responsible for returning the image based on the parameters passed in. As the core version of this method is abstract, you will need to override it when creating our own RasterSource.

• Type:GeoImage
• Description:This method returns an image based on the worldExtent and image width and height.

• worldExtent
  • Type:RectangleShape
  • Description:This parameter represents the worldExtent you want to draw.

• canvasWidth
  • Type:Int32
  • Description:This parameter represents the width of the image you want to draw.

• canvasHeight
  • Type:Int32
  • Description:This parameter represents the height of the image you want to draw.
