public class DisplacementMap extends Effect
FloatMap
. Для каждого пикселя в выводе, соответствующих данных от mapData
получается, масштабируется и смещается scale
и offset
атрибуты, масштабируемые снова размером исходного ввода, отображают и используемый в качестве смещения от целевого пикселя, чтобы получить пиксельные данные от исходного ввода. dst[x,y] = src[(x,y) + (offset+scale*map[x,y])*(srcw,srch)]Значение
(0.0, 0.0)
не определил бы смещения для пиксельных данных тогда как значение (0.5, 0.5)
определил бы смещение половины размера исходного изображения.
Отметьте, что отображение является смещением от целевого пикселя до исходного пиксельного расположения, от которого это выбирается, что означает что, заполняя карту всеми значениями 0.5
переместил бы изображение половиной его размера к верхнему левому, так как каждый целевой пиксель будет содержать данные, которые прибывают из исходного пикселя ниже и направо от этого.
Также отметьте, что этот эффект не корректирует координаты входных событий или любых методов, которые измеряют включение на a Node
. Результаты выбора мыши и методов включения неопределены когда a Node
имеет a DisplacementMap
произведите на месте.
