Constructor & Destructor Documentation

posterize_effect() [1/2]

xtd::drawing::imaging::effects::posterize_effect::posterize_effect ( )

default

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

posterize_effect() [2/2]

xtd::drawing::imaging::effects::posterize_effect::posterize_effect ( int32 levels )

explicit

Initialise the new instance of xtd::drawing::imaging::posterize_effect object with specified levels.

Parameters

levels

The levels value (from 1 to 256).

Remarks

If the level is equal to or greater than 256, the result is identical to the original image.

If the level is equal to or less than 1, the image is black.

Member Function Documentation

apply()

auto xtd::drawing::imaging::effects::posterize_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.
