◆ Clone()

virtual iText.Kernel.Geom.AffineTransform iText.Kernel.Geom.AffineTransform.Clone ( )

inlinevirtual

Creates a "deep copy" of this AffineTransform, meaning the object returned by this method will be independent of the object being cloned.

Returns: the copied AffineTransform.

◆ GetRotateInstance() [1/2]

static iText.Kernel.Geom.AffineTransform iText.Kernel.Geom.AffineTransform.GetRotateInstance ( double angle )

inlinestatic

Get an affine transformation representing a counter-clockwise rotation over the passed angle

Parameters

angle angle in radians to rotate over

Returns

AffineTransform representing the rotation

◆ GetRotateInstance() [2/2]

static iText.Kernel.Geom.AffineTransform iText.Kernel.Geom.AffineTransform.GetRotateInstance	(	double	angle,
		double	x,
		double	y
	)

inlinestatic

Get an affine transformation representing a counter-clockwise rotation over the passed angle, using the passed point as the center of rotation

Parameters

angle	angle in radians to rotate over
x	x-coordinate of center of rotation
y	y-coordinate of center of rotation

Returns

AffineTransform representing the rotation

◆ GetTransformType()

virtual int iText.Kernel.Geom.AffineTransform.GetTransformType ( )

inlinevirtual

Method returns type of affine transformation.

Transform matrix is m00 m01 m02 m10 m11 m12

According analytic geometry new basis vectors are (m00, m01) and (m10, m11), translation vector is (m02, m12). Original basis vectors are (1, 0) and (0, 1). Type transformations classification:

TYPE_IDENTITY
- new basis equals original one and zero translation
TYPE_TRANSLATION
- translation vector isn't zero
TYPE_UNIFORM_SCALE
- vectors length of new basis equals
TYPE_GENERAL_SCALE
- vectors length of new basis doesn't equal
TYPE_FLIP
- new basis vector orientation differ from original one
TYPE_QUADRANT_ROTATION
- new basis is rotated by 90, 180, 270, or 360 degrees
TYPE_GENERAL_ROTATION
- new basis is rotated by arbitrary angle
TYPE_GENERAL_TRANSFORM
- transformation can't be inversed

Returns: the type of this AffineTransform
