This section introduces and explains the usage of some additional command line tools similar to FFmpeg for use in digital preservation workflows (and beyond!).
+ImageMagick is a free and open-source software suite for displaying, converting, and editing raster image and vector image files.
+It's official website can be found here.
+Another great resource with lots of supplemental explanations of filters is available at Fred's ImageMagick Scripts.
+Unlike many other command line tools, ImageMagick isn't summoned by calling its name. Rather, ImageMagick installs links to several more specific commands: convert
, montage
, and mogrify
, to name a few.
convert input_file.ext -resize 750 output_file.ext
This script will also convert the file format, if the output has a different file extension than the input.
+Creates thumbnails for all files in a folder and saves them in that folder.
+mogrify -resize 80x80 -format jpg -quality 75 -path thumbs *.jpg
montage @list.txt -tile 6x12 -geometry +0+0 output_grid.jpg
