fotoresize

Most camera devices take images with a much higher resolution than is necessary or practical for sharing or posting on the web.

This script accepts either a file or directory as an argument, it then downsizes the file or all image files in the directory so that their width and height do not exceed a certain size, defined in pixels.

The script checks to make sure that the files it processes are single-frame image files (e.g. are not GIFs) and then checks to see if they are already below the specified maximum width and height values.

Configuration

No configuration needs to be done by default.

The maximum width and height are set to 1600x1600 and can be changed be editing the maxW and maxH values in the script.

Rescaled images have a tag appended to their file name. The tag can be customized by changing the tag value in the script.

Credits and Thanks

This script relies on the excellent ImageMagick image software suite.

This script will run in any BASH shell on a system that has ImageMagick installeed including Linux, Cygwin-Windows, and OSX.

Usage:

fotoresize <file>|<directory>

To Do

Right now the directory processor only accepts png and jpg files. If there are other image types that would would like included please contact me.
