IFF can store ANY type of metadata. you can link several data packets inside it... for example, most IFF/ILBM images also had a palette block... which defined the colors to use for the image... this made the ILBM pretty flexible. and you could also have GFX packages which included vector drawings AND pre-rendered ILBM block for programs which only supported that.
Some word-processors programs stored an ascii-only version of all the text so that it could be pasted directly within the clipboard engine (which is also iff based, if I remember well!) -MAx ----- Original Message ----- From: "Carl Read" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, November 13, 2001 1:44 AM Subject: [REBOL] Re: Image processing and embedding metadata in images? > On 13-Nov-01, Jason Cunliffe wrote: > > > Hi Carl > > > Thanks for the IFF tip. > > Helpful because I can surely learn something. good reading.
