Converts a given angle from one coordinate system to another. The transformer uses the first coordinate of the passed-in feature and returns the angle of the specified line at the determined angle in the destination coordinate system.它可用于转换在目的地坐标系单元中的许多系统中建立的文本旋转等数据。
要计算新角度，变压器使用：
- input length
- input angle
- 输入点
- source (reader) coordinate system
- 目的地（Writer）坐标系
and then calculates a second point in the source coordinate system by taking the first point and advancing length units in the angle heading. It then reprojects both points to determine the new angle.
使用说明
此功能假定所有坐标系是笛卡尔。
Parameters
Original Line Length
Distance specified in source coordinate system coordinates. You should enter a length that is small enough to avoid distortion, but large enough to get meaningful results (for example, 1 m might be a good choice, although a range of 1 cm to 100 m would be acceptable). If your source system is in degrees, you will have to adjust the length to produce measurable results.
原始线角度
Angle of distance in source coordinate system. The angle is measured counterclockwise from horizontal and is specified in degrees.
源和目的地坐标系
读者和写入坐标系的名称。
Reprojected Angle Attribute
The calculated value is put into the attribute specified by the Reprojected Angle Attribute parameter.
