Interface IRemapFilter

All Superinterfaces:

Serializable

All Known Implementing Classes:

RemapFilter

public interface IRemapFilter
extends Serializable

Provides access to members that control a remap filter.

Remarks

Provides access to the members of IRemapFilter. Similar to the reclass concept, this filters group raster pixel values into classes and creates a raster with those classes. Another benefit of this filter is that you can specify a range of values to be nodata and add it to nodataclass.

Sub remap(pRaster As iRaster, pOutWs As IWorkspace)
Dim pFilter As IRemapFilter
Set pFilter = New RemapFilter

'add classes
pFilter.AddClass 5, 20, 0
pFilter.AddClass 20, 50, 1
pFilter.AddClass 50, 100, 2
pFilter.AddClass 100, 120, 3
pFilter.AddClass 120, 150, 4
pFilter.AddClass 150, 256, 5

'add nodatdclass, all values between 0 and 5 (>= 0 and <5) will turn to nodata in the output
pFilter.AddNoDataClass 0, 5

Dim pSaveAs As ISaveAs
Set pSaveAs = pRaster

'set filter
Dim pFilterOp As IPixelOperation
Set pFilterOp = pRaster
Set pFilterOp.PixelFilter = pFilter

'save out

Method Summary

void	addClass(double minvalue, double maxvalue, double newvalue) Adds a remap class that remaps values in [minvalue,maxvalue) to a give new value.
void	addNoDataClass(double minvalue, double maxvalue) Adds a remap class that remaps values in [minvalue,maxvalue) to NoData.
void	empty() Removes all classes.
int	getClassCount() The number of remapped classes.
boolean	isAllowUnmatched() Indicates if unmatched values should be passed through.
void	putClass(int index, double minvalue, double maxvalue, double newvalue) Puts a remap class at a given class index (starting from 0).
void	queryClass(int index, double[] minvalue, double[] maxvalue, double[] newvalue) Queries a remap class at a given class index (starting from 0).
void	setAllowUnmatched(boolean pAllowUnmatched) Indicates if unmatched values should be passed through.
