Transformer Quick-Reference – FME 2006 GB For detailed information on transformers, open the Workbench Help file and find the Transformers folder.TransformerBrief Description简介（注意并非针对本文，可能有差异）2DArcReplacerReplaces the geometry of the feature with a two-dimensional arc whose shape isset by the parameters, which can be either constant floating point values or thevalues of existing attributes.改为二维圆弧，圆弧的形状由参数控制，例如常数或属性值2DBoxReplacerReplaces the geometry of the feature with a two-dimensional box whoseminimums and maximums are fixed val-ues, or are taken from attributes in theoriginal feature.改为二维矩形，矩形的最大最小坐标为指定的常数或原始要素的属性值2DCreatorCreates a two-dimensional feature using the parameters supplied, and sends itinto the workspace for processing.根据参数创建二维要素，并输入转换流程2DEllipseReplacerReplaces the geometry of the feature with a two-dimensional ellipse whose shapeis set by the parameters.改为二维椭圆，椭圆的形状由参数控制2DForcerRemoves any elevation (Z) coordinates which may (or may not) have beenpresent on the original feature.改为二维要素（删除Z坐标）2DGridCreatorCreates a grid of two-dimensional point features, at the origin and using theoffsets specified.按格网方式生成一批二维点状要素，须指定原点和间距2DGridReplacerReplaces the input features with a grid of two-dimensional point features thathave the specified spacing, and which cover (at least) the bounding box area of allthe features that enter the transformer.将输入的一批要素改为按格网方式生成的二维点状要素，格网的范围（至少）覆盖全部输入要素的外接矩形，格网间距须指定2DPointAdderAdds a two-dimensional point as the last vertex of the feature. The ordinates aretaken from attributes in the original feature.给要素增加一个二维的节点（最后一个节点），其坐标由原...
