We wanted to rasterize (but see below). The effect we wanted to achieve is to have an identifying string printed on the same page as the image. This string could be part of the image (in which case we have to rasterize). But we would be perfectly happy if we can achieve the same result without having to fiddle with the tiff file. We have tons of tiff files to print (to the HPLJ 5Si printer with a XipPrint card), and each of them has a unique identifier. Thank you. -- Weiqi Gao weiqigao@crl.com
