Member Function Documentation
| void GRE::SCRIPTCONTEXT_DRAW::AttachContext | ( | SMLCONTEXT *& | context | ) |
Attach SML context.
After attachment the SCRIPTCONTEXT_DRAW 'owns' the context and will destroy it when necessary. The context pointer is passed by reference and set to NULL on return to prevent external use of the context.
- Parameters:
-
context Context to attach, will set to NULL on return
| ERRVALUE GRE::SCRIPTCONTEXT_DRAW::CreateContext | ( | RVC::GEOMETRIC & | GeoObj | ) |
Create SML context using RVC::GEOMETRIC object.
- Parameters:
-
GeoObj Geometric object (VECTOR, TIN, CAD, etc)
| virtual void GRE::SCRIPTCONTEXT_DRAW::CreateSymbols | ( | ) | [protected, virtual] |
Reimplemented in GRE::SCRIPTCONTEXT_STYLE, and GRE::SCRIPTCONTEXT_LABEL.
| void GRE::SCRIPTCONTEXT_DRAW::DestroyContext | ( | ) |
Destroy attached SML context if any.
| SMLCONTEXT* GRE::SCRIPTCONTEXT_DRAW::GetContext | ( | ) | const [inline] |
Get attached SMLCONTEXT pointer.
Do not free or Destroy() the returned pointer.
| bool GRE::SCRIPTCONTEXT_DRAW::HasContext | ( | ) | const [inline] |
Determine if have SMLCONTEXT attached.
| ERRVALUE GRE::SCRIPTCONTEXT_DRAW::InitDraw | ( | GRE::LAYERDC & | layerdc | ) |
Initialize using layer drawing context.
| ERRVALUE GRE::SCRIPTCONTEXT_DRAW::InitDraw | ( | GRE::LAYER * | layer, | |
| MGD::CONTEXT * | gc, | |||
| const TRANS2D_MAPGEN & | trans, | |||
| bool | Is3D = false | |||
| ) |
Initialize context variables for drawing.
- Parameters:
-
layer Layer gc Drawing device context Is3D 3D setting for CartoScript
| void GRE::SCRIPTCONTEXT_DRAW::SetScaleValues | ( | double | DesignScale, | |
| double | CurrentScale | |||
| ) |
Set scaling values.
