| | 25 | .TH RAS2TIFF 1 "November 2, 2005" "libtiff" |
| | 26 | .SH NAME |
| | 27 | ras2tiff \- create a |
| | 28 | .SM TIFF |
| | 29 | file from a Sun rasterfile |
| | 30 | .SH SYNOPSIS |
| | 31 | .B ras2tiff |
| | 32 | [ |
| | 33 | .I options |
| | 34 | ] |
| | 35 | .I input.ras |
| | 36 | .I output.tif |
| | 37 | .SH DESCRIPTION |
| | 38 | .I ras2tiff |
| | 39 | converts a file in the Sun rasterfile format to |
| | 40 | .SM TIFF. |
| | 41 | By default, the |
| | 42 | .SM TIFF |
| | 43 | image is created with data samples packed (\c |
| | 44 | .IR PlanarConfiguration =1), |
| | 45 | compressed with the Lempel-Ziv & Welch algorithm (\c |
| | 46 | .IR Compression =5), |
| | 47 | and with each strip no more than 8 kilobytes. |
| | 48 | These characteristics can overridden, or explicitly specified |
| | 49 | with the options described below. |
| | 50 | .PP |
| | 51 | Any colormap information in the rasterfile is carried over to the |
| | 52 | .SM TIFF |
| | 53 | file by including a |
| | 54 | .I Colormap |
| | 55 | tag in the output file. |
| | 56 | If the rasterfile has a colormap, the |
| | 57 | .I PhotometricInterpretation |
| | 58 | tag is set to 3 (palette); |
| | 59 | otherwise it is set to 2 (RGB) if the depth |
| | 60 | is 24 or 1 (min-is-black) if the depth is not 24. |
| | 61 | .SH OPTIONS |
| | 62 | .TP |
| | 63 | .B \-c |
| | 64 | Specify a compression scheme to use when writing image data: |
| | 65 | .B "\-c none" |
| | 66 | for no compression, |
| | 67 | .B "\-c packbits" |
| | 68 | for the PackBits compression algorithm, |
| | 69 | .B "\-c jpeg" |
| | 70 | for the baseline JPEG compression algorithm, |
| | 71 | .B "\-c zip |
| | 72 | for the Deflate compression algorithm, |
| | 73 | and |
| | 74 | .B "\-c lzw" |
| | 75 | for Lempel-Ziv & Welch (the default). |
| | 76 | .TP |
| | 77 | .B \-r |
| | 78 | Write data with a specified number of rows per strip; |
| | 79 | by default the number of rows/strip is selected so that each strip |
| | 80 | is approximately 8 kilobytes. |
| | 81 | .SH BUGS |
| | 82 | Does not handle all possible rasterfiles. |
| | 83 | In particular, |
| | 84 | .I ras2tiff |
| | 85 | does not handle run-length encoded images. |
