How do you load a picture slowly and make it fade slowly?

for example like a pic like my avatar and make it slowly fade in and then slowly fade out ...
i know how to make text slowly fade in and fade out but not pics like this i am not looking for the sprinkle effect but a line by line change :S if anyone understood that....

if you mean showing a 1 pixel line at a time, you can just do a for loop like this, and play with the delays and colors.
Turing:

var pic : int := Pic.FileNew ("light.jpg")
setscreen ("offscreenonly")
for decreasing i : Pic.Height (pic) .. 1
    cls
    Pic.Draw (pic, 0, 0, picCopy)
    drawfillbox (0, 0, Pic.Width (pic), i, white)
    View.Update
    delay (1)
end for


Or if this is the line thing you mean.
Turing:

var pic : int := Pic.FileNew ("light.jpg")
var line : array 1 .. Pic.Height (pic) of int
for i : 1 .. upper (line)
    line (i) := 1
end for
setscreen ("offscreenonly")
loop
    cls
    line (Rand.Int (1, upper (line))) := 0
    Pic.Draw (pic, 0, 0, picCopy)
    for i : 1 .. upper (line)
        if line (i) = 1 then
            drawline (0, i, Pic.Width (pic), i, white)
        end if
    end for
    View.Update
    delay (1)
    exit when hasch
end loop


And there's plenty more you can do, juss be creative. Smile

The probable cause for such an error is the picture was not successfully created. Wink Do you have a picture of the same file name in the same folder as the Turing program? Or, did you enter the full path correctly?

Yeah no problem, lol, but I think you misunderstand my signiture. Its used to refer to people who make something complex where it is not needed, or at least that's what I get from it. Confused

sry if u think im a noob but i cannot get those codes to work. I changed the pic name to one on my comp, but it still didnt work. the error message is :
Illegal picture ID number "0". (Problem cause: picture was not successfully created.).

Check that the file name is right. Check that the file is in the same folder as the turing file. Check that your file is of the allowable extensions (no .gifs!)

i did all that and it still doesnt work. i even copy and pasted the code from the help menu and it still gives the same error message as before. to be more specific, the error is on the line "Pic.Draw (picID,..."
code:
var picID: int
        var x, y : int
       
        picID := Pic.FileNew ("Himeji.bmp")
        for i : 1 .. 50
            x := Rand.Int (0, maxx)     % Random x
            y := Rand.Int (0, maxy)     % Random y
            Pic.Draw (picID, x, y, picCopy)
        end for
        Pic.Free (picID)

If you're just going to use "Himeji.bmp" or w/e then here's how you can figure out where that picture need to be. make a new file, and save it, where ever you save that file, "Himeji.bmp" has to be there in that exact same folder. Make sure you include very capital.
