Constructor & Destructor Documentation

SaveLayerRec() [1/4]

SkCanvas::SaveLayerRec::SaveLayerRec ( )

inline

Sets fBounds, fPaint, and fBackdrop to nullptr. Clears fSaveLayerFlags.

Returns

empty SaveLayerRec

Definition at line 689 of file SkCanvas.h.

{}

SaveLayerRec() [2/4]

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

Definition at line 698 of file SkCanvas.h.

            : SaveLayerRec(bounds, paint, nullptr, nullptr, 1.f, saveLayerFlags, /*filters=*/{}) {}

SaveLayerRec() [3/4]

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

Definition at line 713 of file SkCanvas.h.

            : SaveLayerRec(bounds, paint, backdrop, nullptr, 1.f, saveLayerFlags, /*filters=*/{}) {}

SaveLayerRec() [4/4]

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

inline

Sets fBounds, fColorSpace, 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.
colorSpace	If not null, when the layer is restored, a color space conversion will be applied from this color space to the parent's color space. The restore paint and backdrop filters will be applied in this color space. If null, the new layer will inherit the color space from its parent.
saveLayerFlags	SaveLayerRec options to modify layer

Returns

SaveLayerRec fully specified

Definition at line 735 of file SkCanvas.h.

            : SaveLayerRec(bounds, paint, backdrop, colorSpace, 1.f, saveLayerFlags, /*filters=*/{}) {}

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).

Definition at line 753 of file SkCanvas.h.

fBounds

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

hints at layer size limit

Definition at line 740 of file SkCanvas.h.

fColorSpace

const SkColorSpace* SkCanvas::SaveLayerRec::fColorSpace = nullptr

If not null, this triggers a color space conversion when the layer is restored. It will be as if the layer's contents are drawn in this color space. Filters from fBackdrop and fPaint will be applied in this color space.

Definition at line 760 of file SkCanvas.h.

fFilters

FilterSpan SkCanvas::SaveLayerRec::fFilters = {}

Definition at line 745 of file SkCanvas.h.

{};

fPaint

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

modifies overlay

Definition at line 743 of file SkCanvas.h.

fSaveLayerFlags

SaveLayerFlags SkCanvas::SaveLayerRec::fSaveLayerFlags = 0

preserves LCD text, creates with prior layer contents

Definition at line 763 of file SkCanvas.h.
