hello all, i have some tiff files which were created by scanning under WinNT and written by windows imaging. i totally use Linux and do not have access to a Windows system. i am not able to open the tiff file under Linux in any image viewer. i have downloaded the latest version of lib tiff and tiff2png. the output i get from that is appended below. can some one help me to convert this to normal tiff or any other readable format. raj PS: i have send this mail once two days ago, but i did not receive a copy and also did not see any response. i have also searched the archives. so i am reposting this again, if you are getting this for second time kindly accept my apologies. 1.tif: Warning, unknown field with tag 512 (0x200) ignored. 1.tif: Warning, unknown field with tag 513 (0x201) ignored. 1.tif: Warning, unknown field with tag 514 (0x202) ignored. 1.tif: Warning, unknown field with tag 515 (0x203) ignored. 1.tif: Warning, unknown field with tag 519 (0x207) ignored. 1.tif: Warning, unknown field with tag 520 (0x208) ignored. 1.tif: Warning, unknown field with tag 521 (0x209) ignored. 1.tif: Warning, unknown field with tag 32934 (0x80a6) ignored. tiff2png: converting 1.tif to ./1.png TIFF Directory at offset 0x8 Subfile Type: (0 = 0x0) Image Width: 1276 Image Length: 1642 Resolution: 151, 151 pixels/inch Bits/Sample: 8 Compression Scheme: Old-style JPEG Photometric Interpretation: YCbCr FillOrder: msb-to-lsb YCbCr Subsampling: 2, 1 Software: "Oi/GFS, writer v00.06.00P, (c) Wang Labs, Inc. 1990, 1991" Orientation: row 0 top, col 0 lhs Samples/Pixel: 3 Rows/Strip: 8 Planar Configuration: single image plane tiff2png: aspect ratio (hor/vert) = 1 (151 / 151) tiff2png: near-unity aspect ratio tiff2png: 1276x1642x24 image tiff2png: 8 bits/sample, 3 samples/pixel tiff2png: maxval=255 tiff2png error: don't know how to handle PHOTOMETRIC_YCBCR (1.tif)
