| LowLevelGraphicsContext ()=default | |
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.

Returns true if this device is vector-based, e.g.
a printer.
Implemented in LowLevelGraphicsPostScriptRenderer.

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