ETG_InvertRaster

Invert Raster

Recalculates the values of the cells of the input raster in such a way that the cell with the lowest value in the input receives the value of the highest cell and vice versa.
If the raster represents a terrain, the valleys become ridges and the ridges - valleys.

Inputs:

Input raster dataset.
Output raster name and format.

Output:

A raster with inverted values.

Examples:

Input raster.

Inverted raster.

Cross sectional profile of the input and output rasters.

Notes:

The input format accepted are file based rasters - ERDAS IMAGINE or Tagged Image File Format (TIFF).
The .NET ToolBox for ArcGIS Desktop accepts also FileGDB Raster inputs.
For file based rasters initially the name of the output raster define the raster format:
- .img extension (for example raster1.img) - ERDAS IMAGINE image.
- .tif extension (for example raster1.tif) - TIFF image.
- The initial output raster format can be changed by selecting the desired output in the dialog.

Parameters

Expression	Explanation
Function Name	InvertRaster
<input raster>	A String representing the input raster dataset.
<output raster>	A String - the full name of the output raster.

Running the function

ETSPath used in the table below is the full path to ETSRun.exe (E.G. "C:\Program Files\ETSpatial Techniques\ETSurface\ETSRun.exe")

Language	Syntax
Python	subprocess.call([ETSPath, "InvertRaster", "input raster", "output raster"])
.NET using ETSRun.exe	StartInfo.FileName = ETSPath StartInfo.Arguments = "InvertRaster" "input raster" "output raster"
.NET using ETSOutX.dll	InvertRaster(input raster, output raster)
ArcPy	arcpy.InvertRaster("input raster", "output raster")

Notes:

<> - required parameter
{} - optional parameter
See examples for Python , .NET or ArcPy
The argument separator for StartInfo.Arguments is space. If a string might contain a space, you need to double quote it.
