ezcGraphTransformation:: (3 methods):
  __construct()
  multiply()
  transformCoordinate()

Class: ezcGraphTransformation - X-Ref

Class defining transformations

Three dimensional matrices (3x3) may be used to specify transformation of
points, vectors and complexer structures in a two dimensional cartesian
coordinate system. For more details have a look here:
http://en.wikipedia.org/wiki/Transformation_matrix

There are some classes extending this basic tranformation class, to
give you more convinient access to the creation of such transformation
matrices, which are:

- ezcGraphRotation (rotations of objects)
- ezcGraphTranslation (moving of objects)

__construct( array $values = null ) X-Ref

Constructor

Creates a matrix with 3x3 dimensions. Optionally accepts an array to
define the initial matrix values. If no array is given an identity
matrix is created.

param: array $values
return: void

multiply( ezcGraphMatrix $matrix ) X-Ref

Multiplies two matrices

Multiply current matrix with another matrix and returns the result
matrix.

param: ezcGraphMatrix $matrix Second factor
return: ezcGraphMatrix Result matrix

transformCoordinate( ezcGraphCoordinate $coordinate ) X-Ref

Transform a coordinate with the current transformation matrix.

param: ezcGraphCoordinate $coordinate
return: ezcGraphCoordinate
