I have a data supplier that is using a version of Photoshop that writes "Adobe JPEG" files. Apparently these files comply with the JPEG standard but not to the JFIF format. For example, Adobe JPEG files support CMYK JPEG files.
I have reason to believe that Photoshop 2.5 or Photoshop 3.0 wrote these fils. Does anyone know if versions after 3.0 went to JFIF? Did Adobe abandon this format? Exactly when was it supported?
I’ve searched adobe.com and can’t find any reference to Adobe JPEG. These images are causing Java Advanced Imaging (JAI) to do bad things and that is giving us fits.
Most of what I’ve learned about Adobe JPEG came from the document at URL < http://www.fcla.edu/digitalArchive/pdfs/action_plan_bgrounds /jfif.pdf> (search for "Adobe JPEG"). Thank you in advance for any responses.
