Description

GraMaMa creates a mask (either greyscale or black/white) given a prescribed shape (such as circle, ellipse, line, square and rectangle). It replaces the input clip by a mask with the same dimensions and color format.

Requirements

• AviSynth 2.5.8 or greater
• Supported color formats: YV12

Syntax and Parameters

GraMaMa (clip, int "mode", int "a", int "b", int "rad", int "rad2", bool "binarize")

clip   =

Input clip.

int  mode = 1

• 1 : circle
• 2 : square
• 3 : diamond
• 4 : line
• 5 : ellipse
• 6 : rectangle

int  a = width/2

int  b = height/2

(a,b) is the center of the mask. It can be located outside the clip.

int  rad = width/4

rad is the horizontal radius of the mask.

int  rad2 =

rad2 is the vertical radius of the mask (for mode=1,3,4 it is equal to rad; for mode=5,6 (default rad/2) it can be set separately; for mode=2 is results in a vertical gradient mask (when rad2>0).

bool  binarize = false

binarize = false (gradient mask), binarize = true (black and white mask).
