使用Ghostscript将TIFF转换为PDF

Question

你能告诉我如何使用Ghostscript或Postscript将TIFF转换为PDF？

我试着使用这个命令:

gswin32c.exe -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -sOutputFile=o.pdf test.tif

但它不起作用.

它会产生错误:

该libtiff软件包（可在所有主要操作系统平台上使用）附带一个名为tiff2pdf.

$ tiff2pdf -h
  LIBTIFF, Version 4.0.3
  Copyright (c) 1988-1996 Sam Leffler
  Copyright (c) 1991-1996 Silicon Graphics, Inc.
  
  usage:  tiff2pdf [options] input.tiff
  options:
   -o: output to file name
   -j: compress with JPEG
   -z: compress with Zip/Deflate
   -q: compression quality
   -n: no compressed data passthrough
   -d: do not compress (decompress)
   -i: invert colors
   -u: set distance unit, 'i' for inch, 'm' for centimeter
   -x: set x resolution default in dots per unit
   -y: set y resolution default in dots per unit
   -w: width in units
   -l: length in units
   -r: 'd' for resolution default, 'o' for resolution override
   -p: paper size, eg "letter", "legal", "A4"
   -F: make the tiff fill the PDF page
   -f: set PDF "Fit Window" user preference
   -e: date, overrides image or current date/time default, YYYYMMDDHHMMSS
   -c: sets document creator, overrides image software default
   -a: sets document author, overrides image artist default
   -t: sets document title, overrides image document name default
   -s: sets document subject, overrides image image description default 
   -k: sets document keywords
   -b: set PDF "Interpolate" user preference
   -h: usage

因此，获取 PDF 的简单命令是：

$ tiff2pdf -o output.pdf -p A4 -F test.tif

Ghostscript读取PDF和PostScript作为输入,它不读取图像格式,特别是不读取TIFF.但PostScript是一种编程语言,因此完全可以编写PostScript程序来读取TIFF文件(Ghostscript提供的viewgif.ps和viewjpeg.ps程序为GIF和JPEG格式执行此操作)

我确实有一个程序可以执行此操作,直到某个点,并且已经在comp.lang.postscript上发布了几次.它有点大的分享(33Kb),但如果你有兴趣,我可以给你发电子邮件.
