Constructor Detail

Transform

public Transform(int length)

Creates a new Transform instance.

Parameters:

length - the amount of Transform.SingleTransform instances that this Transform instant shall contain and be able to process

Method Detail

addSingleTransform

public void addSingleTransform(Transform.SingleTransform singleTransform)

Adds a Transform.SingleTransform in a list of single transforms to process later.

Parameters:

singleTransform - a Transform.SingleTransform instance

getMultipleTransform

private java.util.List<Transform.SingleTransform> getMultipleTransform()

getAffineTransform

public static AffineTransform getAffineTransform(Transform t,
                                                 float width,
                                                 float height)

Converts the Transform instance, i.e. the list of Transform.SingleTransform instances, to the equivalent AffineTransform instance relatively to the available area, including resolving of percent values to point values.

Parameters:

t - a Transform instance to convert

width - the width of available area, the point value of which is equivalent to 100% for percentage resolving

height - the height of available area, the point value of which is equivalent to 100% for percentage resolving

Returns:

resulting affine transformation instance, accumulated from Transform
