Member Function Documentation

◆ approximateFilteredBounds()

SkRect SkMaskFilter::approximateFilteredBounds ( const SkRect & src ) const

Returns the approximate bounds that would result from filtering the src rect. The actual result may be different, but it should be contained within the returned bounds.

Definition at line 317 of file SkMaskFilter.cpp.

                                                                      {
    SkRect dst;
    as_MFB(this)->computeFastBounds(src, &dst);
    return dst;
}

◆ Deserialize()

sk_sp< SkMaskFilter > SkMaskFilter::Deserialize	(	const void *	data,
		size_t	size,
		const SkDeserialProcs *	procs = `nullptr`
	)

                               kSkMaskFilter_Type, data, size, procs).release()));
}

◆ MakeBlur()

sk_sp< SkMaskFilter > SkMaskFilter::MakeBlur	(	SkBlurStyle	style,
		SkScalar	sigma,
		bool	respectCTM = `true`
	)

static

Create a blur maskfilter.

Parameters

style	The SkBlurStyle to use
sigma	Standard deviation of the Gaussian blur to apply. Must be > 0.
respectCTM	if true the blur's sigma is modified by the CTM.

Returns: The new blur maskfilter
