Member Enumeration Documentation

Bits specifies which aspects of the layer's paint should replace the corresponding aspects on the draw's paint.

kEntirePaint_Bits means use the layer's paint completely. 0 means ignore the layer's paint... except for fColorMode, which is always applied.

Enumerator
kStyle_Bit	use this layer's Style/stroke settings
kTextSkewX_Bit	use this layer's textskewx
kPathEffect_Bit	use this layer's patheffect
kMaskFilter_Bit	use this layer's maskfilter
kShader_Bit	use this layer's shader
kColorFilter_Bit	use this layer's colorfilter
kXfermode_Bit	use this layer's xfermode
kEntirePaint_Bits	Use the layer's paint entirely, with these exceptions: We never override the draw's paint's text_encoding, since that is used to interpret the text/len parameters in draw[Pos]Text. Color is always computed using the LayerInfo's fColorMode.

Member Function Documentation

bool SkLayerDrawLooper::asABlurShadow ( BlurShadowRec * ) const

overridevirtual

If this looper can be interpreted as having two layers, such that.

The first layer (bottom most) just has a blur and translate
The second layer has no modifications to either paint or canvas
No other layers. then return true, and if not null, fill out the BlurShadowRec).

If any of the above are not met, return false and ignore the BlurShadowRec parameter.

Reimplemented from SkDrawLooper.

SkDrawLooper::Context* SkLayerDrawLooper::makeContext	(	SkCanvas *	,
		SkArenaAlloc *
	)		const

overridevirtual

Called right before something is being drawn.

Returns a Context whose next() method should be called until it returns false.
