ThinkGeo.MapSuite.Core.GdiPlusRasterLayer
Note: The page was created before Map Suite 10. Map Suite 10.0 organized many classes into new namespaces and assemblies as well as had a few minor breaks in compatibility. The majority of previously built code should work without modification assuming the new namespaces are added. For guidance on upgrading your existing code, please check out MapSuite 10 Upgrade Guide.
This class represents general image types to be drawn on the map, such as .BMP, .JPG, .PNG, etc.

DrawCore(GeoCanvas,Collection<SimpleCandidate>)
The DrawCore method will be called when the layer is being drawn. It will determine if the image is within the extent and the threshold defined. If these parameters are met, it will query the RasterSource for an image and then apply the other various properties (such as transparency, etc.) on the image. Lastly, it will draw the image on the GeoImage or native image passed into the method.

Public Properties
HasBoundingBox
This property checks to see if a Layer has a BoundingBox or not. If it has no BoundingBox, it will throw an exception when you call the GetBoundingBox() and GetFullExtent() APIs. In GdiPlusRasterLayer, we override this API and mark it as true.

Public Events
StreamLoading
If you wish, you can pass in your own stream to represent the image. The stream can come from a variety of places, including isolated storage, a compressed file, or an encrypted stream. When the image is finished with the stream it will dispose of it, so be sure to keep this in mind when passing the stream in. If you do not pass in an alternate stream, the class will attempt to load the file from the file system using the PathFileName property.
