Hello - it’s me again w/ more crazy questions.

I’m trying to see if this is some how possible.

I’m trying to take a shockwave file (parent) where I have a start frame and and end frame - say start\_frame = 2, end\_frame = 8. I’m trying to make another shockwave file (child) w/ just these 6 frames and their content. I’m trying to do this by reading the binary data of the swf file using the PHP fread() function.

I know PHP has a whole slew of shockwave functions to create SWF files on the fly.

If I could isolate the specific frames from the binary read, I could rewrite the file w/ just those isolated frames.

Am I crazy?
