简介（注意并非针对本文，可能有差异）
|
|
2DArcReplacer
|
Replaces the geometry of the feature with a two-dimensional arc whose shape is set by the parameters, which can be either constant floating point values or the values 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
|
|
2DBoxReplacer
|
Replaces the geometry of the feature with a two-dimensional box whose minimums and maximums are fixed val-ues, or are taken from attributes in the original 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
|
|
2DCreator
|
Creates a two-dimensional feature using the parameters supplied, and sends it into the workspace for processing.
|
根据参数创建二维要素，并输入转换流程
|
|
2DEllipseReplacer
|
Replaces the geometry of the feature with a two-dimensional ellipse whose shape is set by the parameters.
|
改为二维椭圆，椭圆的形状由参数控制
|
|
2DForcer
|
Removes any elevation (Z) coordinates which may (or may not) have been present on the original feature.
|
改为二维要素（删除Z坐标）
|
|
2DGridCreator
|
Creates a grid of two-dimensional point features, at the origin and using the offsets specified.
|
按格网方式生成一批二维点状要素，须指定原点和间距
|
|
2DGridReplacer
|
Replaces the input features with a grid of two-dimensional point features that have the specified spacing, and which cover (at least) the bounding box area of all the 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
|
|
2DPointAdder
|
Adds a two-dimensional point as the last vertex of the feature. The ordinates are taken from attributes in the original feature.
|
给要素增加一个二维的节点（最后一个节点），其坐标由原始要素的属性获得
|
|
2DPointReplacer
|
Replaces the geometry of the feature with a two-dimensional point whose ordinates are taken from attributes in the original feature.
|
改为二维的点，其坐标由原始要素的属性获得
|
|
3DArcReplacer
|
Replaces the geometry of the feature with a two-dimensional arc whose shape is set by the parameters, which can be either constant floating point values or the values of existing attributes.
|
改为二维圆弧（注：原文如此），圆弧的形状由参数控制，例如常数或属性值
|
|
3DCreator
|
Creates a three-dimensional feature using the parameters supplied, and sends it into the workspace for processing.
|
根据参数创建三维要素，并输入转换流程
|
|
3DForcer
|
Sets all the Z coordinates of the feature to the value of the specified attribute (or the entered floating point number).
|
改为三维要素，Z坐标由指定的属性或常数获得
|
|
3DInterpolator
|
Interpolates elevation values along a linear feature from a starting value to an ending value.
|
三维插值：沿着一个线状要素、根据起始值和结束值内插高程
|
|
3DPointAdder
|
Adds a three-dimensional point as the last vertex of the feature. The ordinates are taken from attributes in the original feature.
|
给要素增加一个三维的节点（最后一个节点），其坐标由原始要素的属性获得
|
|
3DPointReplacer
|
Replaces the geometry of the feature with a three-dimensional point whose ordinates are taken from attributes in the original feature.
|
改为三维的点，其坐标由原始要素的属性获得
|
|
Affiner
|
Performs an affine transformation on the coordinates of the feature.
|
坐标仿射变换
|
|
AffineWarper
|
Performs warping operations on the spatial coordinates of features. It is used to adjust a set of observed features so they more closely match some set of reference features.
|
仿射纠正，用于纠正一批要素使之最接近参考要素
