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
levelsThe 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.
