概览

oaEllipse 在 oapy 中可用，可通过 _design 模块访问。

本页汇总 oaEllipse 当前在 oapy 中可用的 Python 接口。

详细说明

The oaEllipse class implements an ellipse shape。 Ellipses are defined by their bounding boxes。 A circle is a special case of an ellipse where the bounding box is square。

方法说明

`obj.getBoundary(points, numSides)`

绑定状态: 已绑定

Python 调用: obj.getBoundary(points, numSides)

This function fills out points with the bounding polygon of this ellipse。 The polygon is generated with the number of sides specified by numSides。

参数

points: The location for the returned array of points for the ellipse。
numSides: The number of sides that define the bounding polygon。

异常

oacEllipseNumSidesInvalid。

Python 示例

from oapy._oa import _design

# assume obj is a oaEllipse
obj.getBoundary(points, numSides)

`obj.setBBox(bBoxIn)`

绑定状态: 已绑定

Python 调用: obj.setBBox(bBoxIn)

This function sets the bBox of this ellipse to the specified value。

参数

bBoxIn: The specified bounding box for the ellipse。

异常

oacEllipseBBoxInvalid。

Python 示例

from oapy._oa import _design

# assume obj is a oaEllipse
obj.setBBox(bBoxIn)

`obj.convertToPolygon(numSides=32)`

绑定状态: 已绑定

Python 调用: obj.convertToPolygon(numSides=32)

This function converts this ellipse to a polygon using the specified number of sides。 The polygon is returned, although it is the same pointer as the ellipse。

参数

numSides: The number of segments to represent the ellipse as a polygon。

异常

oacEllipseNumSidesInvalid。

Python 示例

from oapy._oa import _design

# assume obj is a oaEllipse
obj.convertToPolygon(numSides=32)

`_design.oaEllipse.create(block, layerNum, purposeNum, bBox)`

绑定状态: 已绑定

Python 调用: _design.oaEllipse.create(block, layerNum, purposeNum, bBox)

This function creates an ellipse with the specified attributes。 The specified bBox is checked to verify it does not have a zero area and it is not inverted。

参数

block: The block in which the ellipse is created。
layerNum: The number of the layer on which the ellipse is created。
purposeNum: The number of the purpose on which the ellipse is created。
bBox: The bounding box for the ellipse。

异常

oacEllipseBBoxInvalid。

Python 示例

from oapy._oa import _design

_design.oaEllipse.create(block, layerNum, purposeNum, bBox)

`_design.oaEllipse.genBoundary(ellipseBBox, numSides, boundary)`

绑定状态: 已绑定

Python 调用: _design.oaEllipse.genBoundary(ellipseBBox, numSides, boundary)

This function fills out boundary with the boundary polygon of the ellipse specified by ellipseBBoxIn。 The polygon is generated with the number of sides specified by numSidesIn。

参数

ellipseBBox: The bounding box for the ellipse。
numSides: The number of sides returned。
boundary: The location of the returned point array。

异常

oacEllipseNumSidesInvalid。

Python 示例

from oapy._oa import _design

_design.oaEllipse.genBoundary(ellipseBBox, numSides, boundary)
