<h2 class=top>ICC_Profile Tags</h2>
<p>ICC profile information is used in many different file types including JPEG,
TIFF, PDF, PostScript, Photoshop, PNG, MIFF, PICT, QuickTime and some RAW
formats. While the tags listed below are not individually writable, the
entire profile itself can be accessed via the extra 'ICC_Profile' tag, but
this tag is neither extracted nor written unless specified explicitly.</p>
