| 26 | .SH NAME | |
| 27 | tiffcmp \- compare two | |
| 28 | .SM TIFF | |
| 29 | files | |
| 30 | .SH SYNOPSIS | |
| 31 | .B tiffcmp | |
| 32 | [ | |
| 33 | .I options | |
| 34 | ] | |
| 35 | .I "file1.tif file2.tif" | |
| 36 | .SH DESCRIPTION | |
| 37 | .I Tiffcmp | |
| 38 | compares the tags and data in two files created according | |
| 39 | to the Tagged Image File Format, Revision 6.0. | |
| 40 | The schemes used for compressing data in each file | |
| 41 | are immaterial when data are compared\-data are compared on | |
| 42 | a scanline-by-scanline basis after decompression. | |
| 43 | Most directory tags are checked; notable exceptions are: | |
| 44 | .IR GrayResponseCurve , | |
| 45 | .IR ColorResponseCurve , | |
| 46 | and | |
| 47 | .IR ColorMap | |
| 48 | tags. | |
| 49 | Data will not be compared if any of the | |
| 50 | .IR BitsPerSample , | |
| 51 | .IR SamplesPerPixel , | |
| 52 | or | |
| 53 | .I ImageWidth | |
| 54 | values are not equal. | |
| 55 | By default, | |
| 56 | .I tiffcmp | |
| 57 | will terminate if it encounters any difference. | |
| 58 | .SH OPTIONS | |
| 59 | .TP | |
| 60 | .B \-l | |
| 61 | List each byte of image data that differs between the files. | |
| 62 | .TP | |
| 80ed523f | 63 | .BI \-z " number" |
| 8414a40c VZ |
64 | List specified number of image data bytes that differs between the files. |
| 65 | .TP | |
| 66 | .B \-t | |
| 67 | Ignore any differences in directory tags. | |
| 68 | .SH BUGS | |
| 69 | Tags that are not recognized by the library are not | |
| 70 | compared; they may also generate spurious diagnostics. | |
| 71 | .PP | |
| 80ed523f VZ |
72 | The image data of tiled files is not compared, since the |
| 73 | .I TIFFReadScanline() | |
| 74 | function is used. An error will be reported for tiled files. | |
| 8414a40c VZ |
75 | .PP |
| 76 | The pixel and/or sample number reported in differences may be off | |
| 77 | in some exotic cases. | |
