Constructor & Destructor Documentation

contrast_effect() [1/2]

xtd::drawing::imaging::effects::contrast_effect::contrast_effect ( )

default

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

contrast_effect() [2/2]

xtd::drawing::imaging::effects::contrast_effect::contrast_effect ( double  percent )

explicit

Initialise the new instance of xtd::drawing::imaging::contrast_effect object with specified percent.

Parameters

percent

The percent factor in %.

Member Function Documentation

apply()

void xtd::drawing::imaging::effects::contrast_effect::apply ( xtd::drawing::image &  image ) const

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

percent

double xtd::drawing::imaging::effects::contrast_effect::percent

Gets or sets the percent factor in %.

Parameters

percent

The percent factor in %.

Remarks
