can anyone tell me what I'm missing here? I want to scale a image 10% each time and store it in a array, but I can't get it to work. I commented it out to work though it and it seems to make since, so I guess I don't understand how something works? thanks, CTP Dim ball_active_image(5) ; making ball array ball_active_image(0) = ball_image ; setting 1st array slot For i = 1 To 5 ; starting loop h# = Float(i) ; changing int to float g#= h#/10 ; making g# 10% bigger then h# ball_image = ball_active_image(i-1) ; storeing image in array that will be inlarged ScaleImage ball_active_image(i-1),g#,g# ; scaling image in array slot before this one 10% bigger ball_active_image(i) = ball_active_image(i-1) ; setting this array slot to scaled image ball_active_image(i-1) = ball_image ; restore image in array before this one to proper size Next ; ending loop |

You should use CopyImage() to copy the image. |

Well, thank you, that worked, although, I had never used copyimage before, must have something to do with it in a loop, but I will start using copyimage just to make sure I don't have a snafu like that again. Also there was one more problem my 10% bigger was just 10% it should have been 1+h#/10 Thank you, CTP |

Hmm, or 1.1*h#? What you did before was assigning the image handle to another variable. If you do this: image = loadimage("bmp.bmp") image2 = image, only one image is loaded that can be accesed using both "image" and "image2". If you try printing them, you see the image pointer's value are the same: Print image Print image2 CopyImage makes a "physical" copy of the image. |
