NAME

- - - - - -

tiff2ps − convert a TIFF image to -PostScript™

- -

SYNOPSIS

- - - - - -

tiff2ps [ options ] input.tif -...

- -

DESCRIPTION

- - - - - -

tiff2ps reads TIFF images and -writes PostScript or Encapsulated PostScript (EPS) on the -standard output. By default, tiff2ps writes -Encapsulated PostScript for the first image in the specified -TIFF image file.

- -

By default, tiff2ps will generate PostScript that -fills a printed area specified by the TIFF -tags in the input file. If the file does not contain -XResolution or YResolution tags, then the -printed area is set according to the image dimensions. The -−w and −h options (see below) can -be used to set the dimensions of the printed area in inches; -overriding any relevant TIFF tags.

- -

The PostScript generated for RGB, palette, -and CMYK images uses the colorimage -operator. The PostScript generated for greyscale and bilevel -images uses the image operator. When the -colorimage operator is used, PostScript code to -emulate this operator on older PostScript printers is also -generated. Note that this emulation code can be very -slow.

- -

Color images with associated alpha data are composited -over a white background.

- - −1 -	- - Generate PostScript Level 1 (the default). -	-
- - −2 -	- - Generate PostScript Level 2. -	-
- - −3 -	- - Generate PostScript Level 3. It basically allows one to -use the /flateDecode filter for ZIP compressed TIFF -images. -	-
- - −a -	- - Generate output for all IFDs (pages) in the input -file. -	-
- - −b -	- - Specify the bottom margin for the output (in inches). -This does not affect the height of the printed image. -	-
- - −c -	- - Center the image in the output. This option only shows -an effect if both the −w and the -−h option are given. -	-
- - −d -	- - Set the initial TIFF directory to the -specified directory number. (NB: Directories are numbered -starting at zero.) This option is useful for selecting -individual pages in a multi-page (e.g. facsimile) file. -	-
- - −e -	- - Force the generation of Encapsulated PostScript (implies -−z). -	-
- - −h -	- - Specify the vertical size of the printed area (in -inches). -	-
- - −H -	- - Specify the maximum height of image (in inches). Images -with larger sizes will be split in several pages. Option -−L may be used for specifying size of split -images overlapping. -	-
- - −i -	- - Enable/disable pixel interpolation. This option requires -a single numeric value: zero to disable pixel interpolation -and non-zero to enable. The default is enabled. -	-
- - −L -	- - Specify the size of overlapping for split images (in -inches). Used in conjunction with −H -option. -	-
- - −l -	- - Specify the left margin for the output (in inches). This -does not affect the width of the printed image. -	-
- - −m -	- - Where possible render using the imagemask -PostScript operator instead of the image operator. -When this option is specified tiff2ps will use -imagemask for rendering 1 bit deep images. If this -option is not specified or if the image depth is greater -than 1 then the image operator is used. -	-
- - −o -	- - Set the initial TIFF directory to the -IFD at the specified file offset. This option -is useful for selecting thumbnail images and the like which -are hidden using the SubIFD tag. -	-
- - −p -	- - Force the generation of (non-Encapsulated) -PostScript. -	-
- - −r -	- - Rotate image by 180 degrees. -	-
- - −s -	- - Generate output for a single IFD (page) in the input -file. -	-
- - −w -	- - Specify the horizontal size of the printed area (in -inches). -	-
- - −x -	- - Override resolution units specified in the TIFF as -centimeters. -	-
- - −y -	- - Override resolution units specified in the TIFF as -inches. -	-
- - −z -	- - When generating PostScript Level 2, data is scaled so -that it does not image into the deadzone on a page -(the outer margin that the printing device is unable to -mark). This option suppresses this behavior. When PostScript -Level 1 is generated, data is imaged to the entire printed -page and this option has no affect. -	-

EXAMPLES

- - - - - -

The following generates PostScript Level 2 for all pages -of a facsimile:

- - - - - -

tiff2ps −a2 fax.tif | lpr
-

- - - - - - -

Note also that if you have version 2.6.1 or newer of -Ghostscript then you can efficiently preview facsimile -generated with the above command.

- -

To generate Encapsulated PostScript for a the image at -directory 2 of an image use:

- - - - - -

tiff2ps −d 1 foo.tif
-

- - - - - - -

(Notice that directories are numbered starting at -zero.)

- -

If you have a long image, it may be split in several -pages:

- - - - - -

tiff2ps −h11 −w8.5 −H14 −L.5 foo.tif > foo.ps
-

- - - - - - -

The page size is set to 8.5x11 by −w and -−h options. We will accept a small amount of -vertical compression, so −H set to 14. Any -pages between 11 and 14 inches will be fit onto one page. -Pages longer than 14 inches are cut off at 11 and continued -on the next page. The −L.5 option says to -repeat a half inch on the next page (to improve -readability).

- -

BUGS

- - - - - -

Because PostScript does not support the notion of a -colormap, 8-bit palette images produce 24-bit PostScript -images. This conversion results in output that is six times -bigger than the original image and which takes a long time -to send to a printer over a serial line. Matters are even -worse for 4-, 2-, and 1-bit palette images.

- -

Does not handle tiled images when generating PostScript -Level I output.
