Detailed Description

This class is an MGD::DEVICE that lets you pass a pointer to a fill span function.

This is mostly for use by old code that used to use MgdInitSimple(). In fact, MgdInitSimple() is now implemented using this class.

CONTEXT* MGD::DEVICE_SIMPLE::v_CreateContext (   )  [private, virtual]

Create a GC for drawing. Derived classes may override this and make it return anything derived from MGD::CONTEXT. MGD::CONTEXT's constructor is private, so this is the only way for calling code to create a GC. Reimplemented from MGD::DEVICE.

virtual ERRVALUE MGD::DEVICE_SIMPLE::v_FillSpan (  MGD::CONTEXT *  gc, INT32  x1, INT32  x2, INT32  y )  [inline, private, virtual]

Fill a horizontal span. Many of the default method implementations call this to do all the work. Not all of them even need it., so not pure-virtual. Derived classes that implement this do not need to worry about clipping, as the default implementation in CONTEXT does clipping and then calls this version. If your implementation handles bitmap pattern fills in a way that's optimized for your dest device, you should return CAPABALITY_BitmapFill in GetCapabilities Reimplemented from MGD::DEVICE. Definition at line 162 of file mg2simpl.h.

virtual COLORSPACE MGD::DEVICE_SIMPLE::v_GetColorSpace (   )  const [inline, private, virtual]

Return the "native" COLORSPACE used by the display Image operations using this colorspace will be more effeciant. Reimplemented from MGD::DEVICE. Definition at line 159 of file mg2simpl.h.
