Detailed Description

Layer drawing context.

Contains information needed to actually draw layer on a particular view.

Constructor & Destructor Documentation

GRE::LAYERDC::LAYERDC ( LAYER *  layer,
GRE::VIEW *  view,
MGD::DEVICE *  pDevice = 0,
GRE::DRAWFLAGS  drawflags = GRE::DRAWFLAG_None,
const TRANS2D_MAPGEN *  pTransObjectToDevice = 0 
)

Construct using layer, view and drawing device.

If transformation is provided, a private LAYERVIEW instance will be created with the specified transformation. Typically this is done only in internal GRE implementations.

Parameters:
layer Layer, must not be NULL
view View, should not be NULL
pTransObjectToDevice Optional object/device transformation
GRE::LAYERDC::LAYERDC ( GRE::VIEW *  view,
MGD::DEVICE *  pDevice,
const TRANS2D_MAPGEN &  ObjectToDevice,
GRE::DRAWFLAGS  drawflags = GRE::DRAWFLAG_None

Construct using view, drawing device and transformation.

Does not need a layer, but you need to calculate the transformation and pass it in.

Parameters:
view View, cannot be NULL
pDevice Drawing device, cannot be NULL
GRE::LAYERDC::LAYERDC ( GRE::LAYERSECTION *  pLayerSection,
RENDERTARGET  content,
