| 27 | .SH NAME |
| 28 | tiff2ps \- convert a |
| 29 | .SM TIFF |
| 30 | image to \*(Ps\(tm |
| 31 | .SH SYNOPSIS |
| 32 | .B tiff2ps |
| 33 | [ |
| 34 | .I options |
| 35 | ] |
| 36 | .I "input.tif ..." |
| 37 | .SH DESCRIPTION |
| 38 | .I tiff2ps |
| 39 | reads |
| 40 | .SM TIFF |
| 41 | images and writes \*(Ps or Encapsulated \*(Ps (EPS) |
| 42 | on the standard output. |
| 43 | By default, |
| 44 | .I tiff2ps |
| 45 | writes Encapsulated \*(Ps for the first image in the specified |
| 46 | .SM TIFF |
| 47 | image file. |
| 48 | .PP |
| 49 | By default, |
| 50 | .I tiff2ps |
| 51 | will generate \*(Ps that fills a printed area specified |
| 52 | by the |
| 53 | .SM TIFF |
| 54 | tags in the input file. |
| 55 | If the file does not contain |
| 56 | .I XResolution |
| 57 | or |
| 58 | .I YResolution |
| 59 | tags, then the printed area is set according to the image dimensions. |
| 60 | The |
| 61 | .B \-w |
| 62 | and |
| 63 | .B \-h |
| 64 | options (see below) |
| 65 | can be used to set the dimensions of the printed area in inches; |
| 66 | overriding any relevant |
| 67 | .SM TIFF |
| 68 | tags. |
| 69 | .PP |
| 70 | The \*(Ps generated for |
| 71 | .SM RGB, |
| 72 | palette, and |
| 73 | .SM CMYK |
| 74 | images uses the |
| 75 | .I colorimage |
| 76 | operator. |
| 77 | The \*(Ps generated for |
| 78 | greyscale and bilevel images |
| 79 | uses the |
| 80 | .I image |
| 81 | operator. |
| 82 | When the |
| 83 | .I colorimage |
| 84 | operator is used, \*(Ps code to emulate this operator |
| 85 | on older \*(Ps printers is also generated. |
| 86 | Note that this emulation code can be very slow. |
| 87 | .PP |
| 88 | Color images with associated alpha data are composited over |
| 89 | a white background. |
| 90 | .SH OPTIONS |
| 91 | .TP |
| 92 | .B \-1 |
| 93 | Generate \*(Ps Level 1 (the default). |
| 94 | .TP |
| 95 | .B \-2 |
| 96 | Generate \*(Ps Level 2. |
| 97 | .TP |
| 98 | .B \-3 |
| 99 | Generate \*(Ps Level 3. It basically allows one to use the /flateDecode |
| 100 | filter for ZIP compressed TIFF images. |
| 101 | .TP |
| 102 | .B \-a |
| 103 | Generate output for all IFDs (pages) in the input file. |
| 104 | .TP |
| 105 | .B \-b |
| 106 | Specify the bottom margin for the output (in inches). This does not affect |
| 107 | the height of the printed image. |
| 108 | .TP |
| 109 | .B \-c |
| 110 | Center the image in the output. This option only shows an effect if both |
| 111 | the -w and the -h option are given. |
| 112 | .TP |
| 113 | .B \-d |
| 114 | Set the initial |
| 115 | .SM TIFF |
| 116 | directory to the specified directory number. |
| 117 | (NB: directories are numbered starting at zero.) |
| 118 | This option is useful for selecting individual pages in a |
| 119 | multi-page (e.g. facsimile) file. |
| 120 | .TP |
| 121 | .B \-e |
| 122 | Force the generation of Encapsulated \*(Ps (implies -z). |
| 123 | .TP |
| 124 | .B \-h |
| 125 | Specify the vertical size of the printed area (in inches). |
| 126 | .TP |
| 127 | .B \-H |
| 128 | Specify the maximum height of image (in inches). Images with larger sizes will |
| 129 | be split in several pages. Option |
| 130 | .B \-L |
| 131 | may be used for specifying size of split images overlapping. |
| 132 | .TP |
| 133 | .B \-i |
| 134 | Enable/disable pixel interpolation. This option requires a |
| 135 | single numeric value: zero to disable pixel interpolation and |
| 136 | non-zero to enable. The default is enabled. |
| 137 | .TP |
| 138 | .B \-L |
| 139 | Specify the size of overlapping for split images (in inches). Used in |
| 140 | conjunction with |
| 141 | .B \-H |
| 142 | option. |
| 143 | .TP |
| 144 | .B \-l |
| 145 | Specify the left margin for the output (in inches). This does not affect |
| 146 | the width of the printed image. |
| 147 | .TP |
| 148 | .B \-m |
| 149 | Where possible render using the |
| 150 | .B imagemask |
| 151 | \*(Ps operator instead of the image operator. When this option is specified |
| 152 | .I tiff2ps |
| 153 | will use |
| 154 | .B imagemask |
| 155 | for rendering 1 bit deep images. If this option is not specified |
| 156 | or if the image depth is greater than 1 then the image operator |
| 157 | is used. |
| 158 | .TP |
| 159 | .B \-o |
| 160 | Set the initial |
| 161 | .SM TIFF |
| 162 | directory to the |
| 163 | .SM IFD |
| 164 | at the specified file offset. |
| 165 | This option is useful for selecting thumbnail images and the |
| 166 | like which are hidden using the SubIFD tag. |
| 167 | .TP |
| 168 | .B \-p |
| 169 | Force the generation of (non-Encapsulated) \*(Ps. |
| 170 | .TP |
| 171 | .B \-r |
| 172 | Rotate image by 180 degrees. |
| 173 | .TP |
| 174 | .B \-s |
| 175 | Generate output for a single IFD (page) in the input file. |
| 176 | .TP |
| 177 | .B \-w |
| 178 | Specify the horizontal size of the printed area (in inches). |
| 179 | .TP |
| 180 | .B \-x |
| 181 | Override resolution units specified in the TIFF as centimeters. |
| 182 | .TP |
| 183 | .B \-y |
| 184 | Override resolution units specified in the TIFF as inches. |
| 185 | .TP |
| 186 | .B \-z |
| 187 | When generating \*(Ps Level 2, data is scaled so that it does not |
| 188 | image into the |
| 189 | .I deadzone |
| 190 | on a page (the outer margin that the printing device is unable to mark). |
| 191 | This option suppresses this behavior. |
| 192 | When \*(Ps Level 1 is generated, data is imaged to the entire printed |
| 193 | page and this option has no affect. |
| 194 | .SH EXAMPLES |
| 195 | The following generates \*(Ps Level 2 for all pages of a facsimile: |
| 196 | .RS |
| 197 | .nf |
| 198 | tiff2ps -a2 fax.tif | lpr |
| 199 | .fi |
| 200 | .RE |
| 201 | Note also that if you have version 2.6.1 or newer of Ghostscript then you |
| 202 | can efficiently preview facsimile generated with the above command. |
| 203 | .PP |
| 204 | To generate Encapsulated \*(Ps for a the image at directory 2 |
| 205 | of an image use: |
| 206 | .RS |
| 207 | .nf |
| 208 | tiff2ps -d 1 foo.tif |
| 209 | .fi |
| 210 | .RE |
| 211 | (notice that directories are numbered starting at zero.) |
| 212 | .PP |
| 213 | If you have a long image, it may be split in several pages: |
| 214 | .RS |
| 215 | .nf |
| 216 | tiff2ps -h11 -w8.5 -H14 -L.5 foo.tif > foo.ps |
| 217 | .fi |
| 218 | .RE |
| 219 | The page size is set to 8.5x11 by |
| 220 | .B \-w |
| 221 | and |
| 222 | .B \-h |
| 223 | options. We will accept a small amount of vertical compression, so |
| 224 | .B \-H |
| 225 | set to 14. Any pages between 11 and 14 inches will be fit onto one page. |
| 226 | Pages longer than 14 inches are cut off at 11 and continued on the next |
| 227 | page. The |
| 228 | .B \-L.5 |
| 229 | option says to repeat a half inch on the next page (to improve readability). |
| 230 | .SH BUGS |
| 231 | Because \*(Ps does not support the notion of a colormap, |
| 232 | 8-bit palette images produce 24-bit \*(Ps images. |
| 233 | This conversion results in output that is six times |
| 234 | bigger than the original image and which takes a long time |
| 235 | to send to a printer over a serial line. |
| 236 | Matters are even worse for 4-, 2-, and 1-bit palette images. |
| 237 | .SH BUGS |
| 238 | Does not handle tiled images when generating PS Level I output. |
