| LowLevelGraphicsContext () | |
Interface class for graphics context objects, used internally by the Graphics class.
Users are not supposed to create instances of this class directly - do your drawing via the Graphics object instead.
It's a base class for different types of graphics context, that may perform software-based or OS-accelerated rendering.
E.g. the LowLevelGraphicsSoftwareRenderer renders onto an image in memory, but other subclasses could render directly to a windows HDC, a Quartz context, or an OpenGL context.

| virtual LowLevelGraphicsContext::~LowLevelGraphicsContext | ( | ) | [virtual] |
| virtual bool LowLevelGraphicsContext::isVectorDevice | ( | ) | const [pure virtual] |
Returns true if this device is vector-based, e.g.
a printer.
Implemented in LowLevelGraphicsSoftwareRenderer, and LowLevelGraphicsPostScriptRenderer.
| virtual void LowLevelGraphicsContext::setOrigin | ( | int | x, |
| int | y | ||

Moves the origin to a new position.
The co-ords are relative to the current origin, and indicate the new position of (0, 0).
