But with a GD library variable if I did the above and then edited $varnew then $varold would be effected too. Obviously one way would be to reopen the file or to make a new image and copy it into it. Is there an easier way?

• Is it possible to turn a string with base64 encoded image data into a displayable image in flash lit

  - by ezicus

  I have tried using a data URI to load the image data into a movie clip, but flash lite does not appear to support the data URI scheme. I also thought it might be possible to base64 decode the image data and write it out to a file and load the file back into the movie clip using the file URI scheme. However, I do not see a way to write to the filesystem in the documentation. Am I missing something in the flash lite docs that would allow me to write to the filesystem?
