ESRI.ArcGIS.Client Namespace > ArcGISImageServiceLayer Class : RenderingRule Property

Gets or sets the rendering rule which provides a set of predefined raster functions to dynamically change the display of the ArcGISImageServiceLayer.

Syntax

Visual Basic (Declaration) 
Public Property RenderingRule As RenderingRule
C# 
public RenderingRule RenderingRule {get; set;}

Remarks

The following lists the rendering rule functions, with hyperlinks to conceptual documentation, that are supported by the RenderingRule property:

It is required to create a RenderingRule class and set the appropriate properties in order set the ArcGISImageServiceLayer.RenderingRule property.

Example

C#Copy Code
public void Make_Aspect()

  // Blue integer values. 
  // For example the line:
  // New Integer() {0, 175, 240, 233}
  // means that for the pixel value = 0, create a color where Red is 175, Green is 240, and Blue 
  // is 233.

  // Note:
  // If a particular pixel value is not defined with a color and yet that pixel value is to be 
  // rendered it will be shown as transparent. Only those pixel values that have a defined color 
  // will be rendered with that color. In the example array below, if the pixel value of 2 exists 
  // in the DEM it will render as transparent since no color was explicitly defined in the array 
  // of arrays.
  //
  // A color map is different than a color ramp. Color ramps are defined and behave similar to 
  // color maps with the exception that if a pixel value is to be rendered and it is not explicitly 
  // defined in the array, then a color will automatically be generated that is between two closest 
  // two pixel values for which colors are defined.
  // 
  // The RenderingRule raster functions of ColorMap and ShadedRelief that are used for the 
  // ArcGISImageServiceLayer only use color maps.

  ' Blue integer values. 
  ' For example the line:
  ' New Integer() {0, 175, 240, 233}
  ' means that for the pixel value = 0, create a color where Red is 175, Green is 240, and Blue 
  ' is 233.
  ' 
  ' Note:
  ' If a particular pixel value is not defined with a color and yet that pixel value is to be 
  ' rendered it will be shown as transparent. Only those pixel values that have a defined color 
  ' will be rendered with that color. In the example array below, if the pixel value of 2 exists 
  ' in the DEM it will render as transparent since no color was explicitly defined in the array 
  ' of arrays.
  '
  ' A color map is different than a color ramp. Color ramps are defined and behave similar to 
  ' color maps with the exception that if a pixel value is to be rendered and it is not explicitly 
  ' defined in the array, then a color will automatically be generated that is between two closest 
  ' two pixel values for which colors are defined.
