NAME

       MoveCmd, RotateCmd, ScaleCmd - coordinate transformation commands

SYNOPSIS

       #include <Unidraw/Commands/transforms.h>

DESCRIPTION

       The   Unidraw  library  predefines  three  purely  interpretive  commands  for  performing
       coordinate transformations: MoveCmd defines a translation, RotateCmd defines  a  rotation,
       and ScaleCmd defines a two-dimensional scaling.

MOVECMD PUBLIC OPERATIONS

       MoveCmd(ControlInfo*, float dx = 0, float dy = 0)
       MoveCmd(Editor* = nil, float = 0, float = 0)
              Construct  a  new  MoveCmd,  specifying the translation distances in the horizontal
              (dx) and vertical (dy) dimensions.

       void GetMovement(float&, float&)
              Return the translation distances specified in the constructor.

ROTATECMD PUBLIC OPERATIONS

       RotateCmd(ControlInfo*, float = 0)
       RotateCmd(Editor* = nil, float = 0)
              Construct a new RotateCmd, specifying the rotation angle in degrees.

       float GetRotation()
              Return the rotation angle specified in the constructor.

SCALECMD PUBLIC OPERATIONS

       ScaleCmd(
           ControlInfo*, float sx = 1, float sy = 1, Alignment = Center
       )

       ScaleCmd(Editor* = nil, float = 1, float = 1, Alignment = Center)
              Construct a new ScaleCmd, specifying the scaling factors in the horizontal (sx) and
              vertical  (sy)  dimensions  and  an  alignment suggesting the point about which the
              component should be scaled.

       void GetScaleing(float&, float&)
       Alignment GetAlignment()
              Return the scaling factors and alignment specified in the constructor.
