    RasterBandNameSetter

    套the band name of selected bands on a raster, making raster contents simpler to understand compared to band numbers.

    Jump to Configuration

    典型的用途

    • 将名称添加到栅格带以进行处理要求或清晰度。

    How does it work?

    The RasterBandNameSetter receives raster features and applies either a single name or list of names to the currently selected band or bands.

    To select specific bands, use theRasterSelectorprior to the RasterBandNameSetter.

    名称列表必须提供为FME list attribute。

    This transformer supports raster band selection. Palettes are unaffected.

    使用列表属性进行名称列表

    当输入类型是列表时（输入类型=名称列表）， 一种列表属性that contains band names must be specified.

    The values in the list will be applied to the selected bands, in the order they were selected. The list must contain at least as many elements as there are selected bands. List values are used sequentially.

    List Examples

    鉴于具有三个频带和没有频带名称的输入栅格功能，该表显示了针对与频带名称的相同列表属性的不同组合的预期输出。

    List Attribute*

    选择的乐队*
    (bold)

    得到的乐队名称

    _bandnames{0} = 'OneDog'

    _bandnames{1} = 'TwoCats'

    _Bandnames {2} ='hopfish'

    0.

    频段0：

    Band 1:oneedog.

    Band 2:TwoCats

    *Band numbers start at zero (0), as do list elements. The band name list attribute may have any name.

    ClosedExample:Adding a single band name

    In this example, we will add a band name to a DEM raster. Note that the original raster feature has a single band, with no band name.

    栅格被路由到一个栅格负责范围内。栅格的默认状态是“所选的所有频段”，因此当前选择此栅格的单频带，并将由变压器作用。

    在“参数”对话框中，输入类型is set toSingle Name, and theBand Namespecified isELEVATION。

    The output raster feature now has a band name,ELEVATION。

    Usage Notes

    选择光栅变压器

    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, seeRasters (IFMERaster)。
