Detailed Description

Graphics, not just Images.

CAUGuiGraphic is the base class of all types of graphical objects in CAUGui

The concept of hiding visual representation from actual control objects offers some possibilities:

• Graphics can be images drawn in various ways (rotated, scaled, stacked animation frames, cropped)

• Graphics can use Quartz to render lines, polygons, text

void CAUGuiGraphic::draw (  CGContextRef  context, UInt32  portHeight, eRect *  rect, float  value )  [virtual]

letting Graphics draw themselves Parameters: context  is the CGContextRef to render into portHeight  the height of the Window, needed for "upside down" Quartz drawing rect  the eRect where to draw into, does usually scale the image value  normalized between 0.f and 1.f, needed i.e. from frame based animation Reimplemented in CAUGuiSpinImage, CAUGuiHandleImage, and CAUGuiCroppingImage.
