Detailed Description

An abstraction that is used to store a temporary raster image/framebuffer.

The layer is drawn with a specific offset to the graphics context. ILayers take ownership of the underlying bitmaps In GPU-based backends (NanoVG), this is a texture.

Constructor & Destructor Documentation

ILayer()

ILayer::ILayer ( APIBitmap *  pBitmap, const IRECT &  layerRect, IControl *  pControl, const IRECT &  controlRect  )

inline

Create a layer/offscreen context (used internally)

Parameters

pBitmap	The APIBitmap to use for the layer
layerRect	The bounds of the layer withing the graphics context
pControl	The control that the layer belongs to
controlRect	The bounds of the control
