IMapImage Interface

Provides access to the Map Image Interface.

When To Use

Use IMapImage to access properties of an ExportMapImage result.

Members

	Name	Description
	Height	The height of the image in pixels.
	MapExtent	The geographic extent of the map that is fitted to the height and width of the generated image.
	MapScale	The scale of the generated map image.
	MimeData	Binary data representing the generated image.
	MimeType	The MIME type of the generated image.
	ReferenceDPI	The device resolution of the image specified in the request (dots per inch).
	URL	The URL of the generated image.
	VisibleLayers	Array of the visible layers drawn for the generated map scale.
	Width	The width of the image in pixels.

IMapImage.MapExtent Property

The geographic extent of the map that is fitted to the height and width of the generated image.

Public ReadOnly Property MapExtent As IEnvelope

public IEnvelope MapExtent {get;}

IMapImage.MapScale Property

The scale of the generated map image.

Public ReadOnly Property MapScale As Double

public double MapScale {get;}

IMapImage.VisibleLayers Property

Array of the visible layers drawn for the generated map scale.

Public ReadOnly Property VisibleLayers As ILongArray

public ILongArray VisibleLayers {get;}

Remarks

VisibleLayers is defined by a combination of layer visibility in the TOC (i.e. is the layer "on"?) and layer visibility dependent on map scale. Scale dependency for a layer is set in the original map document. If the layer is scale dependent (i.e. a maximum and/or minimum scale has been set) and the map scale falls out of this range, layer visibility will be false. Do not confuse this property with the visibility property on ILayerDescription which is based solely on layer visibility in the TOC (is the layer "on" or "off"). The IMapImage interface inherits all IImageResult properties.

Inherited Interfaces

Interfaces	Description
IImageResult	Provides access to the Image Result Interface.

Classes that implement IMapImage

Classes	Description
MapImage	The Map Image coclass contains information about the generated map image.

Remarks

The MapImage coclass is a subclass of ImageResult and will inherit all IImageResult properties.
