= gray =
== Syntax == int gray(int r, int g, int b, int rweight, int gweight, int bweight) == Arguments == :r ::The Red pixel color value :g ::The Green pixel color value :b ::The Blue pixel color value :rweight ::The weighting given to the red color in the grayscale algorithm :gweight ::The weighting given to the green color in the grayscale algorithm :bweight ::The weighting given to the blue color in the grayscale algorithm == Return == The new grayscale pixel value. == Description == Applies a simple grayscale effect to a given RGB pixel value, according to the weightings provided. == Example == <code> ctl[0]: "Red Weight", Range=(1,500), Val=250 ctl[1]: "Green Weight", Range=(1,500), Val=250 ctl[2]: "Blue Weight", Range=(1,500), Val=250 ForEveryTile: { int r, g, b; for (y = y_start; y < y_end; y++) { for (x = x_start; x < x_end; x++) { r = src(x,y,0); g = src(x,y,1); b = src(x,y,2); for (z=0; z < 3; z++) { pset(x,y,z, gray(r, g, b, ctl(0), ctl(1), ctl(2))); } } } return true; }</code> == See Also == |
