Images cant be scaled, but sprites can with the 'Scale Sprite' or 'size sprite' commands.

My signature is NOT a moderator plaything! Stop changing it!

Hi Legends's
How's it going.

Hi Mobiius you can indeed scale images without sprites. You have to use a bitmap though. Here is a demo I just cooked up. It shows the image scaling. Just replace "myimage.bmp" with your own bitmap file.

Here is the code. Enjoy

+ Code Snippet

sync on
sync rate 0

load bitmap "myimage.bmp", 1

getWidth = bitmap width(1)
getHeight = bitmap height(1)

set current bitmap 0

do

   cls

    if flag = 0
      inc size
      if size > 50
         size = 50
         flag = 1
      endif
    endif

   if flag = 1
      dec size
      if size < 0
         size = 0
         flag = 0
      endif
    endif


    x = (getWidth * size) / 100
    y = (getHeight * size) / 100

    copy bitmap 1,0,0,getWidth,getHeight,0,0,0,x,y
    center text 320,460,"Darkvee's Size Picture Demo"
sync
loop
