Detailed Description

SaveLayerRec contains the state used to create the layer.

Constructor & Destructor Documentation

SaveLayerRec() [1/3]

SkCanvas::SaveLayerRec::SaveLayerRec ( )

inline

Sets fBounds, fPaint, and fBackdrop to nullptr.

Clears fSaveLayerFlags.

Returns

empty SaveLayerRec

SaveLayerRec() [2/3]

SkCanvas::SaveLayerRec::SaveLayerRec ( const SkRect *  bounds, const SkPaint *  paint, SaveLayerFlags  saveLayerFlags = 0  )

inline

Sets fBounds, fPaint, and fSaveLayerFlags; sets fBackdrop to nullptr.

Parameters

bounds	layer dimensions; may be nullptr
paint	applied to layer when overlaying prior layer; may be nullptr
saveLayerFlags	SaveLayerRec options to modify layer

Returns

SaveLayerRec with empty fBackdrop

SaveLayerRec() [3/3]

SkCanvas::SaveLayerRec::SaveLayerRec ( const SkRect *  bounds, const SkPaint *  paint, const SkImageFilter *  backdrop, SaveLayerFlags  saveLayerFlags  )

inline

Sets fBounds, fPaint, fBackdrop, and fSaveLayerFlags.

Parameters

bounds	layer dimensions; may be nullptr
paint	applied to layer when overlaying prior layer; may be nullptr
backdrop	If not null, this causes the current layer to be filtered by backdrop, and then drawn into the new layer (respecting the current clip). If null, the new layer is initialized with transparent-black.
saveLayerFlags	SaveLayerRec options to modify layer

Returns

SaveLayerRec fully specified

Member Data Documentation

fBackdrop

const SkImageFilter* SkCanvas::SaveLayerRec::fBackdrop = nullptr

If not null, this triggers the same initialization behavior as setting kInitWithPrevious_SaveLayerFlag on fSaveLayerFlags: the current layer is copied into the new layer, rather than initializing the new layer with transparent-black.

This is then filtered by fBackdrop (respecting the current clip).

fBounds

const SkRect* SkCanvas::SaveLayerRec::fBounds = nullptr

hints at layer size limit

fPaint

const SkPaint* SkCanvas::SaveLayerRec::fPaint = nullptr

modifies overlay

fSaveLayerFlags

SaveLayerFlags SkCanvas::SaveLayerRec::fSaveLayerFlags = 0

preserves LCD text, creates with prior layer contents
