im4java Reference

Configuration

You can configure the behaviour of the im4java-library with the following environment-variables and system-properties:

IM4JAVA_TOOLPATH (environment) : Default searchpath for commandline tools . Must use the platform-specific path-delimiter.

im4java.useGM (system-property) : If true, use GraphicsMagick instead of ImageMagick .

im4java.maxProcs (system-property) : The maximum number of asynchronous processes the org.im4java.process.ProcessExecutor will run concurrently. If unset or if the property has the value auto , the number returned by Runtime.availableProcessors() is used. Note that the ProcessExecutor will at least use one process.

Test Cases

The package org.im4java.test contains a growing number of test-cases, demonstrating the various features of the im4java-library. Here is a quick overview.

TestCase1 : Simple use of convert

TestCase2 : Operation and sub-operations

TestCase3 : Using montage

TestCase4 : The ChannelMixer-class

TestCase5 : Using mogrify

TestCase6 : Using identify

TestCase7 : Using composite

TestCase8 : Using the Info-class

TestCase9 : The NoiseFilter-class

TestCase10 : Piping

TestCase11 : Dynamic operations

TestCase12 : Reading BufferedImage

TestCase13 : Writing BufferedImage

TestCase14 : GraphicsMagick

TestCase15 : Using jpegtran

TestCase16 : Asynchronous execution. Basic version.

TestCase16a : Asynchronous execution. This version uses Executors.newSingleThreadExecutor() to aquire a ExecutorService .

TestCase16b : Asynchronous execution. This version uses a ProcessExecutor to run at most two processes in parallel.

TestCase17 : Using ufraw-batch

TestCase18 : Using exiftool

TestCase19 : Using dcraw

TestCase20 : Setting search PATHs

TestCase21 : Parallel processes

TestCase22 : Using the BatchConverter-class
