| | 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 |
| | 63 | .BI \-z " number" |
| | 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 |
| | 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. |
| | 75 | .PP |
| | 76 | The pixel and/or sample number reported in differences may be off |
| | 77 | in some exotic cases. |
