Method Index

o GetOrigin(): Returns the origin (eye position) of a 2D camera.
o GetScale(): Returns the scale value of a 2D camera.
o SetOrigin(CATMathPoint2D): Changes the origin of 2D camera.
o SetScale(double): Changes the scale value of a 2D camera.

Methods

o GetOrigin

public virtual CATMathPoint2D GetOrigin(

)=0

Returns the origin (eye position) of a 2D camera.

o GetScale

public virtual double GetScale(

)=0

Returns the scale value of a 2D camera.

o SetOrigin

public virtual void SetOrigin( CATMathPoint2D iOrigin)=0

Changes the origin of 2D camera. It results a translation of the camera.

Parameters:

iOrigin: New position of the camera origin.

o SetScale

public virtual void SetScale( double iScale)=0

Changes the scale value of a 2D camera.

Parameters:

iScale: New scale value of the camera. This value must be >=0
