Hi Stephen,

Great tutorial, thanks.

Hello! Awesome tutorial, been trying to figure out how to do this for a while now.

When I get to opening to jpeg, I am met with the error:

"Could not complete your request because an unknown or invalid JPEG marker type is found."

Anyone know what might be the problem here?

Cheers

@Lchit: same problem here on PC! Anyone knows the magic?

I got it halfway. Edit the file as binary, but the results still now like above...

ooops: "still noT like above"

I recommend downloading a hex editor like 0xed. Youwould not need to change the extension. Any file can be displayed and changed in hex mode. In order to check the changea you can just hit Save and see if your file is messed up aesthetically or broken. If it is broken, you can just go a few steps back.

Try this with different pixel formats. The result is always different.
