RasterBandOrderer

Specifies the required order of bands in a raster. Bands are reordered according to the input band indices.

Typical Uses

  • Altering raster band order to meet format or processing requirements.

How does it work?

The RasterBandOrderer receives raster features and rearranges their bands according to a specified band order.

The band order is defined by a list of current band indices, in the desired order, separated by spaces. Index numbers start at zero.

Bands in the original raster that are not included in the band list are appended after all specified bands, in their original order. Bands may not be included in the list more than once.

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 combing raster with vector data.

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

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.
