Thank you very much for your reply . I was able to scan the page with duplex mode ..
Basically my requirement is to create a multipage image with optimum size in tiff . I am using the following command to acheive a single tiff file from 2 tiffs. On doing so , I get this # tiffcp -c g4 img1.tiff img2.tiff img3.tiff img3.tiff: Bits/sample must be 1 for Group 3/4 encoding/decoding. img3.tiff: Error, can't write strip 0. I also used the tiffinfo img1.tiff to get the deetails of the file . [rrshah at rajeshoffice ~]$ tiffinfo img2.tiff TIFF Directory at offset 0x8 (8) Subfile Type: (0 = 0x0) Image Width: 850 Image Length: 1100 Resolution: 100, 100 pixels/inch Bits/Sample: 8 Compression Scheme: None Photometric Interpretation: min-is-black Orientation: row 0 top, col 0 lhs Samples/Pixel: 1 Rows/Strip: 1100 Min Sample Value: 0 Max Sample Value: 255 Planar Configuration: single image plane After searching furthure on this case , I found that the tiff files should in Black and White ( or LineArt) .. I then used the mode but there are only 2 modes one is gray and other is colour . Kindly help .. I am almost on the verge of getting this working ..
