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 sug- gesting 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.
