How do you create a buffer ?

I know less about that than you. I tried modifying the offScreen example to use an image rather than shape, but got nowhere. It looks like it would require the use of features found in a few of John's latest examples...I just can't make any sense of it.

Of course you know it! you used it in your sliding puzzle. (remember what data() returns)

Code:
> image=fltk.Fl_PNG_Image("murgaLua.png")
> image_data=image:data()
> =type(image_data)
table
> for field,value in pairs(image_data) do print(field,type(value)) end
1       string
d       number
h       number
w       number
ld      number
> =image_data.d
3
> =image_data.h
155
> =image_data.w
167
> =image_data.ld
0


Here is a small example that should make it clear:

Code:
w=fltk.Fl_Double_Window(200,200,"Image buffer Test")
red=string.char(255,0,0)
green=string.char(0,255,0)
blue=string.char(0,0,255)

buffer=string.rep(string.rep(red,50)..string.rep(green,50)..string.rep(blue,50),
150)
image=fltk.Fl_RGB_Image(buffer,150,150,3,0)
box=fltk.Fl_Box(25,25,150,150)
box:image(image)
box2=fltk.Fl_Box(25,175,150,25,"That sure wasn't hard!")
w:show()
Fl:run()
