RasterBandAdder

Adds a new band to a raster feature.

Jump to Configuration

Typical Uses

  • Adding an alpha band for transparency
  • Altering raster structure to match other raster features

How does it work?

The RasterBandAdder receives raster features and adds a new band to them. A selection of interpretation types is available.

The new band will have the same raster-level properties as the input raster feature - that is, number of rows and columns, resolution, origin, and such.

One cell value must be specified, and will be used for all cells in the new band. The nodata value for the band may be optionally set.

Usage Notes

Choosing a Raster Transformer

FME has an extensive selection of transformers for working with raster data. They can be generally categorized as working with whole rasters, bands, cells or palettes, and those designed for workflow control or combining raster with vector data.

For information on raster geometry and properties, see Rasters (IFMERaster).

Parameters

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.

Dialog Options - Tables

Transformers with table-style parameters have additional tools for populating and manipulating values.
