tiff workflow

• requires imagemagick command line tools
• density defines resolution of output image

convert -density 150 SN-085.pdf SN-085.tif

• requires libtiff

tiffsplit input.tif

• edit individual files (each page should be a file) as necessary using any graphics program, such as photoshop
• since individual tiff files are not the final work product, it would be best to not use compression, since some tools do not work well with certain compression schemes

• requires libtiff

ls -1L *.tif | while read file;do
tiff2pdf -p letter -o "${file}".pdf "${file}"
done

• requires libtiff

tiffutil -cat x*.tif -out test.tif

• requires imagemagick command line tools

convert -adjoin x*.tif output.tif

• requires libtiff
• this example uses the -c flag, which is set to lzw compression for much smaller files

tiffcp -c lzw x*.tif output2.tif

• requires pdftk
• this example does not include compression, so with uncompressed tif images, the file size is very large

pdftk *.pdf cat output combined.pdf

• requires libtiff
  • compress file using lzw compression:

    tiffcp -c lzw input.tif output.tif

  • convert to grayscale, and use lzw compression:

    tiff2bw -c lzw input.tif output.tif

  • compress file using CCITT Group 4 compression:(The CCITT Group 3 and Group 4 compression algorithms can only be used with bilevel data - 1 bit black and white images)

    tiffcp -c g4 input.tif output.tif

• requires imagemagick command line tools
  • convert to 1-bit, using CCITT Group 4 compression (black and white)

    convert -monochrome -compress Groupt4 input.tif output.tif

  • convert to 1-bit (black and white) specifying threshold for black:

    convert -monochrome -black-threshold 35768 input.tif output.tif

• convert a bunch of files into monochrome 1-bit images, with CCITT Group 4 compression, then combine them into one multipage tiff file, and finally convert them into one pdf file:

  ls -1L x*.tif|while read file; do convert -monochrome -compress Group4 "${file}" "${file}".bw.tif; done
  
  tiffutil -cat *.bw.tif -out tifoutput.tif
  
  tiff2pdf tifoutput.tif output.pdf
