----

Prerequisites:

This program runs under any OS,
(e.g. Win2K/XP/Vista/W7x86/W7-64/OSX/Linux/Solaris/AIX...) so long as you have
<><> Java version 1.6 <><> or later installed (32-bit or 64-bit Java).
See http://mindprod.com/jgloss/installingjava.html for details.

----

Installing on a PC:

Download source and compiled class files to run on your own machine as an application.
First install a recent Java JDK or JVM.
See http://mindprod.com/jgloss/installingjava.html.
To install, extract the zip download with WinZip
(or similar unzip utility) into any directory you please,
often J:\ --  ticking off the "use folder names" option.
To run as an application,type:
java -ea -jar J:\com\mindprod\cropper\cropper.jar {put any parms here}

adjusting as necessary to account for where the jar file is.

----

Installing on a MacIntosh:

Use Safari to download source and compiled class files to run on your own machine as an application.
Safari will automatically unpack the zip into ~/Downloads (version 10.5)
[or on the Desktop (version 10.4 and earlier)].
First install a recent Java JDK or JVM.
See http://mindprod.com/jgloss/installingjava.html.
You may optionally move the download tree to a permanent home.
I don't have a MacIntosh, just a PC, so I can't test my Java programs for Mac compatibility.
In theory they should work without problems, but in practice that does not always happen.
If you have problems please, let me know, preferably with screenshots and complete verbatim error messages.
To run as an application, without parameters, just double click the jar file.

To run as an application with parameters, in bash shell type:
open Terminal.app
cd ~/Desktop
java -ea -jar com/mindprod/cropper/cropper.jar {put any parms here}

adjusting as necessary to account for where the jar file is.

----

Rebuilding:

The zip already contains the necessary class and jar files, so unless you modify
the program, there is no need to recompile the source or rebuild the jar.
Configure.java basedir="E:/" in rebuild.xml to the drive where your files are.
Use ANT and rebuild.xml, not build.xml, to recompile and recreate the jar.

----

Use:

Cropper converts a set of jpg, png and gif files to a common size, e.g.  
for an animated gif.  It uses a mixture of cropping and scaling.  All you 
have to do is specify the desired size. 

It will ignore all files except those with extension .jpg .png and .gif.
E.g. no .JPEG. 

To convert a single file, type:

  java -jar C:\com\mindprod\cropper\cropper.jar  200 300 rabbit.gif

where 200x300 pixels is the desired size.

The results replace the old file, so you had better make a backup just in 
case this is not what you want.  

You can also list several files on the command line:

  java -jar C:\com\mindprod\cropper\cropper.jar 200 300 rabbit.gif C:\mydir\cat.png

To use convert the current directory of jpg, png and gif files:

  java -jar C:\com\mindprod\cropper\cropper.jar 200 300 .

to convert a whole directory tree of images:

    java -jar C:\com\mindprod\cropper\cropper.jar 200 300 -s E:\imagedirs

Sorry no wildcards, just . , and ..

DON'T USE WILDCARDS unless you deeply understand how they work.  Windows 
expands them, not cropper, and feeds them to cropper (or any other 
program) as a giant list of all the directories and files in the current 
directory.  Cropper will thus tend process all the files in your 
directories, when you just meant to process the files in the current 
directory.  

If you have the jar extension set up as executable, you can abbreviate:

  C:\com\mindprod\cropper\cropper.jar 200 300 .
  
There is a companion utilty called rightsize that will tell you which 
files are in a given size range.  

The nested green rectangles icon is intended to suggest cropping an image 
down.
