四边形#
- class astropy.visualization.wcsaxes.Quadrangle(anchor, width, height, resolution=100, vertex_unit=Unit('deg'), **kwargs)[源代码]#
基类:
Polygon
创建一个表示经纬度四边形的面片。
四边形的边缘位于经度恒定的两条直线和纬度恒定的两条直线上(或相关坐标系中的等效组件名称,例如赤经和赤纬)。请注意,等纬线不是大圆圈。
不像
matplotlib.patches.Rectangle
,则此面片的边将渲染为曲线(如果适用于WCS变换)。- 参数:
- anchorPYTHON:元组或数量 [:ref: 'angle']
- width :
Quantity
[:ref: 'angle' ]数量 [:ref: 'angle'] 四边形在经度上的宽度(或者,例如赤经)
- height :
Quantity
[:ref: 'angle' ]数量 [:ref: 'angle'] 四边形在纬度上的高度(或者,例如赤纬)
- resolution :
int
,可选PYTHON:int,可选 组成四边形每边的点数-增加此值可获得更平滑的四边形。
- vertex_unit :
Unit
[:ref: 'angle' ]单位 [:ref: 'angle'] 应定义生成多边形的单位-这应该与转换(例如WCS转换)期望作为输入的单位相匹配。
笔记
其他关键字参数传递给
Polygon
- 参数:
- xy : (
N
,2)array
(N
, 2)array
- closed : bool ,默认:
True
布尔,默认:PYTHON:TRUE 多边形是否闭合(即,具有相同的起点和终点)。
