Interface IImageResult

All Superinterfaces:

Serializable

All Known Subinterfaces:

ILayoutImage, IMapImage

All Known Implementing Classes:

ImageResult, LayoutImage, MapImage, SimpleMapImage

public interface IImageResult
extends Serializable

Provides access to the Image Result Interface.

Remarks

MapServer output is created using ExportMapImage on IMapServer and the following methods on IMapServerLayout: ExportLayout, ExportLegend, ExportNorthArrow and ExportScaleBar. SymbolImage on MapServerLegendClass is also an ImageResult. In order to control the size of an exported map image, IMapServerInit contains two properties: MaxImageHeight and MaxImageWidth . The default value for these properties is 2048 pixels.

When To Use

Use IImageResult to access properties of MapServer output images.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
