i am using d3d_set_projection_ext (wich has an argument called angle, it affects on how much space is visible) in my 3d game, i build it on pc with 1680x1050 display, and when i tryed to play it on another PC with 1280x1024 screen size, it was scaled to that screen size,

for temporarly solution i wrote a script that finds out the best fit to the screen size, but then there are blank spaces around, i useed this code:

var dw, dh,dr,rr;

dw=display_get_width()
dh=display_get_height()
window_set_fullscreen(argument0)
if (room_width=dw and room_height<=dh) or (room_width<=dw and room_height=dh) or (room_width=dw and room_height=dh)
{return 0 exit}
else
{dr=dw/dh
rr=room_width/room_height

if rr>dr
{room_set_height(room0,dw/room_width*room_height)
room_set_width(room0,dw)}
else
{room_set_width(room0,dh/room_height*room_width)
room_set_height(room0,dh)
}

now i am searching for a way how to use full screen size, (no blank spaces), and i can not figure out how to do this with out scaling the picture, can i calculate the view angle and then insert it in that function, previously mentioned? if that would be posible can someone writes how to calculate that? or any better suggestion to avoid scaling the picture?

thank you in advance, mcf

I am trying to make advanced image editor, which also needs to know how to take a color to pieces.
for exemple with code:  make_color_rgb(222,111,122) , i get code for color, i can also get the code with draw_getpixel(x,y),  
now i need to know how can i get from this code values for red, green blue,   i need exactly oposite procedure of this: make_color_rgb(222,111,122),

can anyone help me with this? i would be really grateful.
