Method makeDistantLitSpecular

shared/java/ImageFilter.java:973–981

Create a filter that calculates the specular illumination from a distant light source, interpreting the alpha channel of the input as the height profile of the surface (to approximate normal vectors). @param x The direction to the distance light (X component) @param y The di

(float x, float y, float z, int lightColor, float surfaceScale, float ks, float shininess, @Nullable ImageFilter input, @Nullable Rect crop)
