using bitmapDataUnlimited i am able to create bitmap of only 4000 pixel of height and width. i need to create bitmap of 8000 pixels of height and width.

I fixed the Background color issue thanks for helping me.

Sorry I actually don’t get what you want to do! Like written above, you can create Bitmaps of any size with BitmapDataUnlimited but it’s NOT for loading images.

the error has nothing to do with BitmapDataUnlimited, it just tells you that it takes very long to encode the JPG … one solution is to change the minimum script execution time (there is a compiler argument in the flex sdk for that) or you use another JPG encoder, the one your are using is damn slow. just search in google and you’ll find at least 5 better ones.

Hi Martin,

Thanks for your reply.

I have tried the solution which you provided for background color issue.
bdu.create(4000,4000, false, 0xff0000);)

when i make transferency = false
i am getting the below error.

Error #1502: A script has executed for longer than the default timeout period of 15 seconds.

hey Sangeeta,

I don’t get your request … BitmapDataUnlimited is not a Class for loading big Images, it’s for creating huge Bitmaps on runtime. Anyways loading big images shouldn’t be a problem through the normal AS3 methods….

background getting black: you create a transparent bitmap and encode a JPG out of it … JPGs don’t have an alpha channel so it gets black. Instead create a nontransparent bitmap (bdu.create(4000,4000, false, 0xff0000);)
