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.
