A transformation attribute can encompass multiple transformation operation (e.g. "translate(10,20) scale(30,40)".

A transformation attribute can encompass multiple transformation operation (e.g. "translate(10,20) scale(30,40)". This method splits the original transformation string into multiple strings so that they can be handled separately. the transformation value a list containing strings describing a single transformation operation

This method decides which transformation operation the given transformation strings maps onto.

string containing a transformation operation the mapped AffineTransform object

Creates a skewY transformation.

values of the transformation AffineTransform for the skew operation

Creates a skewX transformation.

values of the transformation AffineTransform for the skew operation

Creates a rotate transformation.

values of the transformation AffineTransform for the rotate operation

Creates a scale transformation.

values of the transformation AffineTransform for the scale operation

Creates a translate transformation.

values of the transformation AffineTransform for the translate operation

Creates a matrix transformation.

values of the transformation AffineTransform for the matrix keyword

This method extracts the transformation name given a transformation.

the transformation the name of the transformation

This method extracts the values from a transformation.

the transformation values of the transformation
