Hi,
with a simple approach I got this image - here is the code

// render with image resolution and No AA. Method is very memory intensive for
large image sizes!

#version 3.7;

global_settings {
        assumed_gamma 1
}

#include "stdinc.inc"

camera {
        orthographic
        location <0,0,-2>
        look_at 0
        right x*image_width
        up y*image_height
}

#declare image_width_Old = image_width;
#declare image_ratio = image_width/image_height;
#declare image_height_Old = image_width_Old/image_ratio;

#declare pig_map =
function {
        pigment {
                image_map {jpeg "glasses" gamma 2.2}
                scale <image_width_Old,image_height_Old,1>
        }
}

#declare nx = 0;
#while (nx < image_width)
        #declare ny = 0;
        #while (ny < image_height)
                #declare paint_pig = pig_map (nx+0.5,ny+0.5,0);
                box {
                        0, 1
                        pigment {color srgb <max (paint_pig.x,
1-paint_pig.x),max (paint_pig.y, 1-paint_pig.y),max (paint_pig.z,
1-paint_pig.z)>*2-1}
                        finish {emission 1 diffuse 0}
                        translate <nx-image_width*0.5,ny-image_height*0.5,0>
                }
                #declare ny = ny+1;
        #end
        #declare nx = nx+1;
        #debug concat (str (nx/image_width*100, 0, 1)," % processed \n")
#end
