Transparency... Is it Possible??

hmmm... i think turing automatically turns 16ms too 256 colors i'm not sure... =/

yeah... because even if you tried to use like RGB.AddColour and put it into the array... you would still need to use whatdotcolour.

of course, the other option would be to write a jpg decoder if you are know enough about jpgs to do so mehehe

I though Turing (v4) loads .jpg

[PaddyLong]

it does... but he wants 16m colour jpgs.. turing only does 256 colours

[krishon]

it does? probably cuz i haven't used it in a while...when i made my game i had to use bitmaps...very, very old school...well not that old skool

you can load a picture in turing with as many colours as you want. you can draw that picture in turing without any colour loss. but if you want to do anything with the pixels that the picture is composed of, you'll only be using 256 colours. turing will just find the closest matching colour from the 256 palette. example:
draw a pic in turing (a 24bit bitmap for example). now go over every pixel in the picture using a double for loop and draw the pixel using whatdotcolour as the colour.

code:

% draw the picture at (0, 0) for x : 0 .. picturewidth     for y : 0 .. pictureheight         drawdot (x, y, whatdotcolour (x, y))     end for end for

now you'll have the same picture except it's drawn in 256 colours. and quite likely to look quite ugly. maybe even fugly.

that's what I was talking about when I said

I think .png's can have transperant backrounds, and that 'would' work in turing, but turing doesnt work with png's with now, Anyway, Ive seen someone in my school make a spaceship game like star trek, and the ships overlapped each other, and you couldnt see any leftover color from the spaceship, it was a solid ship, not a ship encased into a rectangle. I'll ask him as soon as possible how he did it. But I hope the future holds png support for turing, it would make our lives much easier.

One thing you could do to make part of your pictures transparent is, you could make a color transparent, by using the Pic.SetTransparentColor, which chooses the color thats transparent on the picture. Its prolly the easiest way, but ill ask that guy what he did anyway. So just draw your ship or character, and make the rest of the rectangle brightgreen for example, and declare that brightgreen is transparent. Lol, its a funny way of doing things although.

var shippic : int := Pic.FileNew ("ship.bmp")
Pic.SetTransparentColor (shippic, brightgreen)

Simple as that , and ya, fer sure some of those other methods are defintely slow as hell.

Just go into wordperfect or word or whatever, and ceate a watermark on that page, then print screen key then go in paint, and crop it down
