Methods

	Name	Description
	CreateTranslation	Creates a translation PdfMatrix with the specified offsets.
	Equals(Object)	Determines whether the specified Object is equal to this PdfMatrix instance. (Overrides ValueTypeEquals(Object))
	Equals(PdfMatrix)	Determines whether the other PdfMatrix is equal to this PdfMatrix instance.
	GetHashCode	Returns a hash code for this PdfMatrix instance. (Overrides ValueTypeGetHashCode)
	Invert	Inverts this PdfMatrix structure.
	Multiply	Premultiplies the PdfMatrix representing the additional transformation with the PdfMatrix representing the existing transformation, thus producing the PdfMatrix representing the combined transformation.
	Rotate	Prepends a rotation of the specified angle (counter clockwise) at the specified point to this PdfMatrix structure.
	Scale	Prepends the specified scale about the specified point of this PdfMatrix.
	Skew	Prepends a skew of the specified angle (counter clockwise) in the x and y dimensions to this PdfMatrix.
	ToString	Returns a String that represents this PdfMatrix instance. (Overrides ValueTypeToString)
	Transform(PdfPoint)	Transforms the specified PdfPoint by this PdfMatrix.
	Transform(PdfQuad)	Transforms the specified PdfQuad by this PdfMatrix.
	Translate	Prepends a translation of the specified offsets to this PdfMatrix structure.

Operators

	Name	Description
	Equality(PdfMatrix, PdfMatrix)	Determines whether first and second PdfMatrixs are equal.
	Inequality(PdfMatrix, PdfMatrix)	Determines whether first and second PdfMatrixs are not equal.
	Multiply(PdfMatrix, PdfMatrix)	Premultiplies the PdfMatrix representing the additional transformation with the PdfMatrix representing the existing transformation, thus producing the PdfMatrix representing the combined transformation.
