oaTransform

模块: oapy._oa._base 导入: from oapy._oa import _base

概览

oaTransform 在 oapy 中可用，可通过 _base 模块访问。

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

详细说明

The oaTransform class implements a 2-D transformation including orientation and translation。 This class consists of an orientation (angle and mirroring information) and an offset in the X and Y directions。 This information and the functions for modifying the transform are encapsulated in this class。 Note: when a transform is applied that contains both an orientation change and a translation, the orientation change is applied first。 OpenAccess can use oaTransform to transform various geometric objects, including figures ( oaFig::move ), boxes ( oaBox::transform ), and point arrays ( oaPointArray::transform )。 For more information, see Using Transforms in the Programmer's Guide。

构造函数

_base.oaTransform()

obj = _base.oaTransform()

_base.oaTransform(offsetIn, orientIn=oacR0)

obj = _base.oaTransform(offsetIn, orientIn=oacR0)

_base.oaTransform(xOffsetIn, yOffsetIn, orientIn=oacR0)

obj = _base.oaTransform(xOffsetIn, yOffsetIn, orientIn=oacR0)

_base.oaTransform(orientIn)

obj = _base.oaTransform(orientIn)

_base.oaTransform(xform1, xform2)

obj = _base.oaTransform(xform1, xform2)

obj.offset()

obj.xOffset()

绑定状态: 已绑定

Python 调用: obj.xOffset()

This function is the const version of xOffset() 。 This function gets the value currently set in the delta X portion of the offset, but cannot modify the contents。

返回

• The delta X portion of the offset of this transform。

from oapy._oa import _base

# assume obj is a oaTransform
obj.orient()

obj.offset()

绑定状态: 已绑定

Python 调用: obj.offset()

This function returns a reference to the offset of the transform。 The offset represents the delta X and delta Y of the transform。

Python 示例

from oapy._oa import _base

# assume obj is a oaTransform
obj.offset()

obj.xOffset()

绑定状态: 已绑定

Python 调用: obj.xOffset()

This function returns a reference to the delta X portion of the offset。

Python 示例

from oapy._oa import _base

# assume obj is a oaTransform
obj.xOffset()

obj.yOffset()

绑定状态: 已绑定

Python 调用: obj.yOffset()

This function returns a reference to the delta Y portion of the offset。

Python 示例

from oapy._oa import _base

# assume obj is a oaTransform
obj.yOffset()

obj.orient()

绑定状态: 已绑定

# assume obj is a oaTransform
obj.orient()

obj.set(offsetIn, orientIn=oacR0)

绑定状态: 已绑定

Python 调用: obj.set(offsetIn, orientIn=oacR0)

This function sets the offset and orientation of this transform object to be the same as the concatenation of the two given transforms。 The resulting orientation equals the concatenation of the orientations of the two given transforms; the resulting offset equals the offset of the first given transform transformed by the second given transform。

参数

• xform1: the first transform to concatenate。
• xform2: the second transform to concatenate。
