Hi, I'm trying to use GIL to read a Group 4 TIFF file. Below is the output of tiffinfo for this file. With this code: gray8_image_t img; tiff_read_image("killer2-tiffg4.tif", img); I'm getting the following exception: class std::ios_base::failure: tiff_read_view: input view type is incompatible with the image type --------------------------------------- tiffinfo killer2-tiffg4.tig TIFF Directory at offset 0x8 (8) Subfile Type: multi-page document (2 = 0x2) Image Width: 1728 Image Length: 2292 Resolution: 204, 196 pixels/inch Bits/Sample: 1 Compression Scheme: CCITT Group 4 Photometric Interpretation: min-is-white FillOrder: msb-to-lsb Orientation: row 0 top, col 0 lhs Samples/Pixel: 1 Rows/Strip: 2292 Planar Configuration: single image plane Page Number: 0-0 Software: GPL Ghostscript 8.56 DateTime: 2007:05:04 14:17:27 Group 4 Options: (0 = 0x0) TIFF Directory at offset 0x225ce (140750) Subfile Type: multi-page document (2 = 0x2) Image Width: 1728 Image Length: 2292 Resolution: 204, 196 pixels/inch Bits/Sample: 1 Compression Scheme: CCITT Group 4 Photometric Interpretation: min-is-white FillOrder: msb-to-lsb Orientation: row 0 top, col 0 lhs Samples/Pixel: 1 Rows/Strip: 2292 Planar Configuration: single image plane Page Number: 1-0 Software: GPL Ghostscript 8.56 DateTime: 2007:05:04 14:17:29 Group 4 Options: (0 = 0x0) --------------------------------------- Ideas? regards, josuegomes at gmail dot com
