26 | .TH TIFFSV 1 "September 20, 2005" "libtiff" | |
27 | .SH NAME | |
28 | tiffsv \- save an image from the framebuffer in a | |
29 | .SM TIFF | |
30 | file (Silicon Graphics version) | |
31 | .SH SYNOPSIS | |
32 | .B tiffsv | |
33 | [ | |
34 | .I options | |
35 | ] | |
36 | .I output.tif | |
37 | [ | |

39 | ] | |
40 | .SH DESCRIPTION | |
41 | .I tiffsv | |
42 | saves all or part of the framebuffer in a file using the | |
43 | Tag Image File Format, Revision 6.0. | |
44 | By default, the image is saved with data samples packed (\c | |
45 | .IR PlanarConfiguration =1), | |
46 | compressed with the Lempel-Ziv & Welch algorithm (\c | |
47 | .IR Compression =5), | |
48 | and with each strip no more than 8 kilobytes. | |
49 | These characteristics can be overridden, or explicitly specified | |
50 | with the options described below. | |
51 | .SH OPTIONS | |
52 | .TP | |
53 | .B \-b | |
54 | Save the image as a greyscale image | |
55 | as if it were processed by | |
56 | .IR tiff2bw (1). | |
57 | This option is included for compatibility with the standard | |
58 | .IR scrsave (6D) | |
59 | program. | |
60 | .TP | |
61 | .B \-c | |
62 | Specify the compression to use for data written to the output file: | |
63 | .B none | |
64 | for no compression, | |
65 | .B packbits | |
66 | for PackBits compression, | |
67 | .B jpeg | |
68 | for baseline JPEG compression, | |
69 | .B zip | |
70 | for Deflate compression, | |
71 | and | |
72 | .B lzw | |
73 | for Lempel-Ziv & Welch compression (default). | |
74 | .IP | |
75 | .SM LZW | |
76 | compression can be specified together with a | |
77 | .I predictor | |
78 | value. | |
79 | A predictor value of 2 causes | |
80 | each scanline of the output image to undergo horizontal | |
81 | differencing before it is encoded; a value | |
82 | of 1 forces each scanline to be encoded without differencing. | |
83 | LZW-specific options are specified by appending a ``:''-separated | |
84 | list to the ``lzw'' option; e.g. | |
85 | .B "\-c lzw:2" | |
86 | for | |
87 | .SM LZW | |
88 | compression with horizontal differencing. | |
89 | .TP | |
90 | .B \-p | |
91 | Specify the planar configuration to use in writing image data. | |
92 | By default, | |
93 | .I tiffsv | |
94 | will create a new file with the data samples packed contiguously. | |
95 | Specifying | |
96 | .B "\-p contig" | |
97 | will force data to be written with multi-sample data packed | |
98 | together, while | |
99 | .B "\-p separate" | |
100 | will force samples to be written in separate planes. | |
101 | .TP | |
102 | .B \-r | |
103 | Specify the number of rows (scanlines) in each strip of data | |
104 | written to the output file. | |
105 | By default, | |
106 | .I tiffsv | |
107 | attempts to set the rows/strip | |
108 | that no more than 8 kilobytes of data appear in a strip. | |
109 | .SH NOTE | |
110 | Except for the use of | |
111 | .SM TIFF, | |
112 | this program is equivalent to the standard | |
113 | .I scrsave | |
114 | program. | |
115 | This means, for example, that you can use it in conjunction with | |
116 | the standard | |
117 | .IR icut | |
118 | program simply by creating a link called | |
119 | .IR scrsave , | |
120 | or by creating a shell script called | |
121 | .I scrsave | |
122 | that invokes | |
123 | .I tiffgt | |
124 | with the appropriate options. | |
125 | .SH BUGS | |
126 | If data are saved compressed and in separate planes, then the | |
127 | rows in each strip is silently set to one to avoid limitations | |
128 | in the | |
129 | .BR libtiff (3TIFF) | |
130 | library. | |
