New Script: mt_line

Code:
#mt_line Ver 1.0 by jmac698
#A utility to create relative coordinates of a line for use with Masktools V2

n=12
str=mt_line(n,0,true,n/2)#Create a horizontal line ending with (0,0) (left line)
messageclip("'"+str+"'")

function mt_line(int "hor_radius", int "ver_radius", bool "zero", int "position"){
    #mt_line(int hor_radius(1), int ver_radius(0), bool zero(true), string position(0))
    #Creates a relative coordinates list that can be used in mt_convolution, mt_mappedblur, luts(x), mt_expand and mt_inpand
    #Requires Masktools v2a30+ (mt_freerectangle)
    #zero decides whether the center of the form is included or not. 
    #One of hor_radius or ver_radius must be zero
    #position is the position of (0,0).  Zero indicates that it is centered.
    #Bugs:  zero support is non-functional due to a bug in masktools
    #  returns 0 0 for radius=0, following underlying function
    hor_radius=default(hor_radius,1)
    ver_radius=default(ver_radius,0)
    assert(hor_radius==0 || ver_radius==0,"mt_line:  hor_radius or ver_radius must be zero")
    zero=default(zero,true)
    position=default(position,0)
    x1=hor_radius==0?0:-position-(hor_radius-1)/2
    y1=ver_radius==0?0:-position-(ver_radius-1)/2
    x2=hor_radius==0?0:-position+hor_radius/2#this is one more than x1 on even radius
    y2=ver_radius==0?0:-position+ver_radius/2
    #mt_freerectangle : int top_x(-1), int top_y(-1), int bottom_x(1), int bottom_y(1), bool zero(true)
    mt_freerectangle(x1, y1, x2, y2, zero)#automagically work when masktools is fixed
}
