(keitai-l) Re: Decoding .gif or .jpeg images in iAppli

Thanks Gary,	
	       Thanks for your quick reply.   Hmmm...  it will be quite
disapointing if we dont find a way to put the decoded image into memory
other than the display buffer. We have no problem doing this with standard
Java or even J2ME.   The other questioon I have is do we have access to the
display buffer data after an image is displayed?

You can modify the bitstream by first of all reading the data from the
server into a byte array.  Once it's in a byte array you can manipulate
it as you wish.  The DoJa API doesn't allow you to create an image
directly from a byte array so you should put the byte data into the
scratch pad.  You can then create the image from the data stored in the
scratch pad.

I don't think it's possible to manipulate an image once it has been
unencoded into an Image object.

Hope this helps!
