copy-image-resizer

------------------

An CLI tool written in Java for resizing images.

Recursively transfers a tree of files and directories and resizes images. 

Why?

----

If you have fully-fledged operating system like some GNU/Linux distribution,

you will probably use better tool for resizing images.

In Debian or Ubuntu you can easilly install ImageMagick:

	apt install imagemagick

and resize images:

	convert ${input} -resize 1200x1200 -quality 80 ${output};

or write some shell script around it.

But if you need a multiplatform tool with minimal requirements,

the copy-image-resizer might be useful.

Instalation

-----------

cd java/copy-image-resizer/

ant

compiled program is in: dist/copy-image-resizer.jar

you can run it directly:

	java -jar dist/copy-image-resizer.jar

or install it somewhere and run through th wrapper script:

	scripts/copy-image-resizer.sh

(link it somewhere on your $PATH as „copy-image-resizer“)

TODO: .rpm and .deb packages

Usage

-----

copy-image-resizer supports these options:

--input-dir                 (mandatory)

	one parameter: path to the input directory

--output-dir                (mandatory)

	one parameter: path to the output directory

--size                      (mandatory, can be used multiple times to generate multiple resolutions)

	1. parameter: width          (integer)

	2. parameter: height         (integer)

	3. parameter: resizeSmaller  (boolean)    whether smaller images should be also scaled

--size-named                (alternative to --size)

	1. parameter: width          (integer)

	2. parameter: height         (integer)

	3. parameter: resizeSmaller  (boolean)

	4. parameter: directory      (string)     output sub-directory for this resolution (default in --size is WIDTHxHEIGHT e.g. 64x64)

--skip-errors               (optional, alternative to --skip-errors-silently)

	no parameters

	errors will be just logged and program will fail at the end if any errors

	(default behavior is: fail on first error)

--skip-errors-silently      (optional, alternative to --skip-errors)

	no parameters

	errors will be just logged and program will report success even if there were any errors

Example:

copy-image-resizer --input-dir MyPhotos/ --output-dir MyBlog/ --size 800 600 false --size 1600 1200 false --size-named 300 300 false thumnails

Will generate three output resolutions in separate directories: „MyBlog/800x600“, „MyBlog/1600x1200“ and „MyBlog/thumbnails“
