Prerequisite
Etymology
DSText is a method of managing the drawing of text onto a PixelCanvas.
Synopsis
DSText is designed to have the same interface as any other 'shape'
extending DisplayShape. Much of the functionality is exactly the same,
and hence provides a usefull wrapper for text in an 'annotations' context.
There are generally two ways to make DisplayShape(s); To create them in
"one hit" by providing arguments to the constructor, or by using the
default constructor and then the "setOptions" method. A simple interface
for all classes inheriting from the
DisplayShape class is provided
by DisplayShapeInterface.
Motivation
To create a text wrapper which behaved in the same was as any other
DisplayShape
Example
Member Description
DSText()
DSText(const DSText& other)
DSText(const Float& xPos, const Float& yPos, const String& text = "Label", const Bool& hasHandles = True, const Bool& drawHandles = True)
virtual ~DSText()
Constructors and destructors
virtual void draw(PixelCanvas* pix)
virtual void move(const Float& dX, const Float& dY)
virtual void rotate(const Float& angle)
virtual Bool inObject(const Float& xPos, const Float& yPos)
virtual void changePoint(const Vector<Float>& newPos)
virtual void changePoint(const Vector<Float>& newPos, const Int nPoint)
virtual void scale(const Float& scaleFactor)
virtual void setCenter(const Float& xPos, const Float& yPos)
virtual Vector<Float> getCenter()
Functions to ensure consistancy with the "DisplayShape" interface.
Get and set options
This is a bit messy, so seperate it out
Update handle positions
Display::TextAlign toEnum(const Int fromInt)
Cast from int to enum
