hello, i've recently gotten an epson perfection 4490 photo scanner, which
works fairly well except that xsane will not scan in its optical resolution
of 4800x4800 dpi and none of several frontends i've tried, including iscan
downloaded from epson's own website, can access the scanner's infrared dust
removal (digital ice) when scanning film. looking through mailing list
archives, i've found that ir dust removal is and has long been supported in
a few other scanners, such as the nikon coolscan series, and so i was
wondering what, if anything, can be done to utilize dust removal in this
scanner. thank you all for your time.
