IRasterStretchMinMax Interface (ArcObjects .NET 10.8 SDK)
|
This document is archived and information here might be outdated. Recommended version. |
Provides access to min/max members which control contrast stretching.
| Name | Description | |
|---|---|---|
 |
CustomStretchMax | The custom maximum value for stretch renderer type "Minimum-Maximum". |
|
CustomStretchMin | The custom minimum value for stretch renderer type "Minimum-Maximum". |
 |
StretchMax | The maximum value used for stretching cell values. |
|
StretchMin | The minimum value used for stretching cell values. |
|
UseCustomStretchMinMax | Indicates whether to use the custom minimum/maximum values for stretch renderer type "Minimum-Maximum". |
| Classes | Description |
|---|---|
| RasterStretchColorRampRenderer | A renderer with a color ramp for rasters with continuous values. |
The IRasterStretchMinMax interface allows specification of custom minimum and maximum values when rendering a raster band using a linear stretch. This interface is useful when multiple images need to be displayed with same stretch.
