Transformation

A utility class for building transformation matrices.

Constructors

Transformation


(matrix?: Matrix)

Creates a transformation from the specified matrix, if any.

Parameters

matrix?


Matrix

The initial transformation matrix.

Methods

addObserver

Adds an observer to be notified for changes.

Parameters
observer	`GeometryObserver`	The observer to add.

Returns
`Transformation`	The current Arc instance.

clone

Creates a new instance with the same transformation matrix.

Returns
`Transformation`	A new Transformation instance with the same matrix.

equals

Compares this transformation with another instance.

Parameters
other	`Transformation`	The transformation to compare with.

Returns
`boolean`	true if the transformation matrix is the same. Otherwise, returns `false`.

matrix

Gets the current transformation matrix for this transformation.

Returns
`Matrix`	The current transformation matrix.

multiply

Multiplies the transformation by another one. The underlying transformation matrix is updated in-place.

Parameters
transformation	`Transformation`	The transformation to multiply by.

Returns
`Transformation`	The current Transformation instance.

observers

Returns the list of observers.

Returns
`GeometryObserver[]`	The current observers.

removeObserver

Stops notifying the specified observer for changes.

Parameters
observer	`GeometryObserver`	The observer to remove.

Returns
`Transformation`	The current Arc instance.

resume

Resumes the notification to all observers for changes.

Returns
`Transformation`	The current Arc instance.

rotate

Sets the rotation with the specified parameters.

Parameters
angle	`number`	The angle of rotation in decimal degrees. Measured in a clockwise direction with 0 (zero) pointing "right". Negative values or values greater than 360 are normalized.
center	`number[] \| Point`	The center of rotation.

Returns
`Transformation`	The current transformation instance.

scale

Sets scale with the specified parameters.

Parameters
scaleX	`number`	The scale factor on the X axis.
scaleY	`number`	The scale factor on the Y axis.
origin?	`number[] \| Point`	The scale origin. Defaults to [0, 0].

Returns
`Transformation`	The current Transformation instance.

suspend

Suspends the change notifications to all observers.

Returns
`Transformation`	The current Arc instance.

translate

Sets the translation with the specified parameters.

Parameters
x	`number`	The distance to translate along the X axis.
y	`number`	The distance to translate along the Y axis.

Returns
`Transformation`	The current transformation instance.
