I hope this well asked questios :P

I'm trying to draw the text via pixel dots :

function render_frame(f, t)
local text = overlua_datastring or "Bingo !"
local w, h = f.width, f.height
           surface = cairo.image_surface_create(w, h, "argb32")
contex = surface.create_context()
draw_text(contex,30,240,50,text,1,0,0,1)
 
for i = 0 , w do
for j = 0,h do
--[[ I really don't know why I'm doing this >< ....
if I didn't test every pixel , the script never run , at the same time , it's no diffrent 
if I test "r" , "g" or "blue" .....they all give me what I want ....
well , Idon't care , since it work fine ]] 
 
local  r, g, b = surface.get_pixel(i, j)
if r == 255  then --the original text is pure red
 
 
draw_text(contex,7,i,j+30,".",1,1,0,1)
 
 
end
 
end
end
 
f.overlay_cairo_surface(surface,0,0)
 
end
 
function draw_text(ctx,font_size,xPos,yPos,text_to_draw,red,green,blue,alpha)
ctx.select_font_face("Disney Comic", "", "bold")
ctx.set_source_rgba(red, green, blue , alpha)
ctx.set_font_size(font_size)
ctx.move_to(xPos, yPos)
ctx.text_path(text_to_draw)
ctx.fill()
end

it works fine and draw the text via pixel dots , but there's a problem

-I want to know how to get rid of the original text & keep the the "pixel dots" one ...

I tried to give it zero alpha , but the both disappear >_< ..EDIT : also make two surface for each one then kill the original won't work(actually it's stupid:P)

-is there any better way to draw text via pixel dots

- any hints of how to make something :
