27 | .SH NAME | |
28 | tiffcmp \- compare two | |
29 | .SM TIFF | |
30 | files | |
31 | .SH SYNOPSIS | |
32 | .B tiffcmp | |

36 | .I "file1.tif file2.tif" | |
37 | .SH DESCRIPTION | |
38 | .I Tiffcmp | |
39 | compares the tags and data in two files created according | |
40 | to the Tagged Image File Format, Revision 6.0. | |
41 | The schemes used for compressing data in each file | |
42 | are immaterial when data are compared\-data are compared on | |
43 | a scanline-by-scanline basis after decompression. | |
44 | Most directory tags are checked; notable exceptions are: | |
45 | .IR GrayResponseCurve , | |
46 | .IR ColorResponseCurve , | |
47 | and | |
48 | .IR ColorMap | |
49 | tags. | |
50 | Data will not be compared if any of the | |
51 | .IR BitsPerSample , | |
52 | .IR SamplesPerPixel , | |
53 | or | |
54 | .I ImageWidth | |
55 | values are not equal. | |
56 | By default, | |
57 | .I tiffcmp | |
58 | will terminate if it encounters any difference. | |
59 | .SH OPTIONS | |
60 | .TP | |
61 | .B \-l | |
62 | List each byte of image data that differs between the files. | |
63 | .TP | |
64 | .B \-z number | |
65 | List specified number of image data bytes that differs between the files. | |
66 | .TP | |
67 | .B \-t | |
68 | Ignore any differences in directory tags. | |
69 | .SH BUGS | |
70 | Tags that are not recognized by the library are not | |
71 | compared; they may also generate spurious diagnostics. | |
72 | .PP | |
73 | The image data of tiled files is not compared, since the TIFFReadScanline() | |
74 | function is used. A error will be reported for tiled files. | |
75 | .PP | |
76 | The pixel and/or sample number reported in differences may be off | |
77 | in some exotic cases. | |
