Created an attachment (id=501) [details] Tiff file that has compression scheme None I have a file tussaus_none.tif, which has Compression Scheme: None, as the following tiffinfo reports: # tiffinfo tussaus_none.tif TIFF Directory at offset 0x68e48e (6874254) Subfile Type: (0 = 0x0) Image Width: 8787 Image Length: 6255 Resolution: 1199.95, 1199.95 pixels/inch Bits/Sample: 1 Compression Scheme: None Photometric Interpretation: min-is-white Orientation: row 0 top, col 0 lhs Samples/Pixel: 1 Rows/Strip: 6255 Planar Configuration: single image plane Software: Adobe Photoshop CS4 Windows DateTime: 2012:04:24 03:27:30 When I try to change Compression Scheme to jbig, it fails: # tiffcp -c jbig tussaus_none.tif tussaus_jbig.tif JBIG: Multistrip images not supported in encoder. tussaus_jbig.tif: Error, can't write strip 0. This error is wrong because there is only one strip, which has 6255 rows. So no multistrip. If I change the Scheme first to zip: # tiffcp -c zip -r -1 tussaus_none.tif tussaus_zip.tif then jbig succeeded: tiffcp -c jbig tussaus_zip.tif tussaus_jbig.tif and the report confirms that: # tiffinfo tussaus_jbig.tif TIFF Directory at offset 0x25e70 (155248) Subfile Type: (0 = 0x0) Image Width: 8787 Image Length: 6255 Resolution: 1199.95, 1199.95 pixels/inch Bits/Sample: 1 Compression Scheme: ISO JBIG Photometric Interpretation: min-is-white Orientation: row 0 top, col 0 lhs Samples/Pixel: 1 Rows/Strip: 6255 Planar Configuration: single image plane Software: Adobe Photoshop CS4 Windows DateTime: 2012:04:24 03:27:30 I tested also lzw as an intermediate Scheme and it succeeded also, so it seems that problematic one is Compression Scheme None. This bug is odd because all 81 tests passed, so there should not be this like bug, but may be there is no test for tiffcp scheme:none -> scheme:jbig.

The patch here seems to fix this: https://web.archive.org/web/20160719070826/http://www.asmail.be/msg0054670467.html
On further testing, the patch by Yuriy M Kaminskiy (linked above) appears to break *decoding* JBIG -encoded tiff files: With the patch applied, I can create jbig encoded tiffs using: $ tiffcp -c jbig in.tif jbig.tif But the following then fails: $ tiffcp -c g4 jbig.tif g4.tif
