Constructor & Destructor Documentation

blur_effect() [1/5]

xtd::drawing::imaging::effects::blur_effect::blur_effect ( )

default

Initialise the new instance of xtd::drawing::imaging::blur_effect object.

blur_effect() [2/5]

xtd::drawing::imaging::effects::blur_effect::blur_effect ( int32 radius )

explicit

Initialise the new instance of xtd::drawing::imaging::blur_effect object with specified horizontal and vertical radius.

Parameters

radius

The radius of the blur in pixels.

blur_effect() [3/5]

xtd::drawing::imaging::effects::blur_effect::blur_effect	(	int32	radius,
		bool	expand_edge )

Initialise the new instance of xtd::drawing::imaging::blur_effect object with specified horizontal and vertical radius, and expand edge boolean.

Parameters

radius	The radius of the blur in pixels.
expand_edge	true if the bitmap expands by an amount equal to the radius so that it can have soft edges. false if the bitmap remains the same size and the soft edges are clipped.

blur_effect() [4/5]

xtd::drawing::imaging::effects::blur_effect::blur_effect	(	int32	horizontal_radius,
		int32	vertical_radius )

Initialise the new instance of xtd::drawing::imaging::blur_effect object with specified horizontal and vertical radius.

Parameters

horizontal_radius	The horizontal radius of the blur in pixels.
vertical_radius	The vertical radius of the blur in pixels.

blur_effect() [5/5]

xtd::drawing::imaging::effects::blur_effect::blur_effect	(	int32	horizontal_radius,
		int32	vertical_radius,
		bool	expand_edge )

Initialise the new instance of xtd::drawing::imaging::blur_effect object with specified horizontal and vertical radius, and expand edge boolean.

Parameters

horizontal_radius	The horizontal radius of the blur in pixels.
vertical_radius	The vertical radius of the blur in pixels.
expand_edge	true if the bitmap expands by an amount equal to the radius so that it can have soft edges. false if the bitmap remains the same size and the soft edges are clipped.

Member Function Documentation

apply()

auto xtd::drawing::imaging::effects::blur_effect::apply ( xtd::drawing::image & image ) const -> void

overrideprotectedvirtual

Apply the effect.

Parameters

graphics	The graphics to apply effect.
image	The image where the effect is applied.

Implements xtd::drawing::imaging::effects::effect.

Member Data Documentation

expand_edge

bool xtd::drawing::imaging::effects::blur_effect::expand_edge

Gets or sets a value that indicates whether the bitmap expands by an amount equal to the blur radius.

Parameters

expand_edge

true if the bitmap expands by an amount equal to the radius so that it can have soft edges. false if the bitmap remains the same size and the soft edges are clipped.

horizontal_radius

int32 xtd::drawing::imaging::effects::blur_effect::horizontal_radius

Gets or sets the horizontal radius value.

Parameters

horizontal_radius

The horizontal radius of the blur in pixels.

Remarks

If the horizontal_radius is 0, there will be no horizontal blurring.

vertical_radius

int32 xtd::drawing::imaging::effects::blur_effect::vertical_radius

Gets or sets the vertical radius value.

Parameters

vertical_radius

The vertical radius of the blur in pixels.

Remarks

If the vertical_radius is 0, there will be no vertical blurring.
