OdGeScale2d Class

Syntax

C++

class OdGeScale2d;

Description

Methods

extractScale	Returns the scale vector corresponding to the lengths of the column vectors of the transformation matrix.
getMatrix	Returns the transformation matrix equivalent to this scale vector.
inverse	Returns the inverse of this scale vector.
invert	Sets this scale vector to its inverse, and returns a reference to this scale vector.
isEqualTo	Returns true if and only if scaleVec is identical to this one, within the specified tolerance.
isProportional	Returns true if and only if the scaling matrix corresponding to this scale vector isUniScaledOrtho().
postMultBy	Sets this scale vector to the product (this scale vector) * (rightSide), and returns a reference to this scale vector.
preMultBy	Sets this scale vector to the product leftSide * (this scale vector), and returns a reference to this scale vector.
removeScale	Returns the scale vector corresponding to the lengths of the column vectors of the transformation matrix, and sets the scale factor of the matrix to 1 .
set	Sets this scale vector to the specified X and Y factors, and returns a reference to this vector.
setToProduct(const OdGeScale2d&, const OdGeScale2d&)	This is the overview for the setToProduct method overload.

Operators

!=	Inequality operator for the OdGeScale2d object. Returns true if this scale vector is not equal to the input scale vector.
*(const OdGeScale2d&)	This is the overview for the * operator overload.
*=(const OdGeScale2d&)	This is the overview for the *= operator overload.
==	Equality operator for the OdGeScale2d object. Returns true if this scale vector is equal to the input scale vector.
OdGeMatrix2d	Returns the equivalent 2D transformation matrix.
OdGeScale3d	Returns the equivalent 3D scale vector [sx sy 1].
[](unsigned int)	This is the overview for the [] operator overload.
