extends the number of image file formats supported in Java, using the javax.imageio.* package. +The main purpose of this project is to provide support for formats not covered by the JDK itself. + +Support for formats is important, both to be able to read data found +"in the wild", as well as to maintain access to data in legacy formats. +Because there is lots of legacy data out there, we see the need for open implementations of readers for popular formats. +The goal is to create a set of efficient and robust ImageIO plug-ins, that can be distributed independently. + +---- + +## Features + +Mainstream format support + +#### JPEG + +* Read support for the following JPEG flavors: + * YCbCr JPEGs without JFIF segment (converted to RGB, using embedded ICC profile) + * CMYK JPEGs (converted to RGB by default or as CMYK, using embedded ICC profile ) + * Adobe YCCK JPEGs (converted to RGB by default or as CMYK, using embedded ICC profile) + * JPEGs containing ICC profiles with interpretation other than 'Perceptual' + * JPEGs containing ICC profiles with class other than 'Display' + * JPEGs containing ICC profiles that are incompatible with stream data + * JPEGs with corrupted ICC profiles + * JPEGs with corrupted `ICC_PROFILE` segments + * JPEGs using non-standard color spaces, unsupported by Java 2D + * Issues warnings instead of throwing exceptions in cases of corrupted or non-conformant data where ever the image data can still be read in a reasonable way +* Thumbnail support: + * JFIF thumbnails (even if stream contains inconsistent metadata) + * JFXX thumbnails (JPEG, Indexed and RGB) + * EXIF thumbnails (JPEG, RGB and YCbCr) +* Metadata support: + * JPEG metadata in both standard and native formats (even if stream contains inconsistent metadata) + * `javax_imageio_jpeg_image_1.0` format (currently as native format, may change in the future) + * Illegal combinations of JFIF, Exif and Adobe markers, using "unknown" segments in the + "MarkerSequence" tag for the unsupported segments (for `javax_imageio_jpeg_image_1.0` format) +* Extended write support in progress: + * CMYK JPEGs + * YCCK JPEGs + +#### JPEG-2000 + +* Possibly coming in the future, pending some license issues. + +If you are one of the authors, or know one of the authors and/or the current license holders of either the original jj2000 package or the JAI ImageIO project, please contact me +(I've tried to get in touch in various ways, without success so far). + +#### Adobe Photoshop Document (PSD) + +* Read support for the following file types: + *

BufferedImage image = ImageIO.read(file); + +This will load the first image of the file, entirely into memory. + +The basic and simplest form of writing is: + + if (!ImageIO.write(image, format, file)) { + // Handle image not written case + } + +This will write the entire image into a single file, using the default settings for the given format. + +The plugins are discovered automatically at run time. See the [FAQ](#faq) for more info on how this mechanism works. + +## Advanced usage + +If you need more control of read parameters and the reading process, the common idiom for reading is something like: + + // Create input stream + ImageInputStream input = ImageIO.createImageInputStream(file); + + try { + // Get the reader + Iterator readers = ImageIO.getImageReaders(input); + + if (!readers.hasNext()) { + throw new IllegalArgumentException("No reader for: " + file); + } + + ImageReader reader = readers.next(); + + try { + reader.setInput(input); + + // Optionally, listen for read warnings, progress, etc. + reader.addIIOReadWarningListener(...); + reader.addIIOReadProgressListener(...); + + ImageReadParam param = reader.getDefaultReadParam(); + + // Optionally, control read settings like sub sampling, source region or destination etc. + param.setSourceSubsampling(...); + param.setSourceRegion(...); + param.setDestination(...); + // ... + + // Finally read the image, using settings from param + BufferedImage image = reader.read(0, param); + + // Optionally, read thumbnails, meta data, etc... + int numThumbs = reader.getNumThumbnails(0); + // ... + } + finally { + // Dispose reader in finally block to avoid memory leaks + reader.dispose(); + } + } + finally { + // Close stream in finally block to avoid resource leaks + input.close(); + } + +Query the reader for source image dimensions using `reader.getWidth(n)` and `reader.getHeight(n)` without reading the +entire image into memory first. + +It's also possible to read multiple images from the same file in a loop, using `reader.getNumImages()`. + + +If you need more control of write parameters and the writing process, the common idiom for writing is something like: + + // Get the writer + Iterator writers = ImageIO.getImageWritersByFormatName(format); + + if (!writers.hasNext()) { + throw new IllegalArgumentException("No writer for: " + format); + } + + ImageWriter writer = writers.next(); + + try { + // Create output stream + ImageOutputStream output = ImageIO.createImageOutputStream(file); + + try { + writer.setOutput(output); + + // Optionally, listen to progress, warnings, etc. + + ImageWriteParam param = writer.getDefaultWriteParam(); + + // Optionally, control format specific settings of param (requires casting), or + // control generic write settings like sub sampling, source region, output type etc. + + // Optionally, provide thumbnails and image/stream metadata + writer.write(..., new IIOImage(..., image, ...), param); + } + finally { + // Close stream in finally block to avoid resource leaks + output.close(); + } + } + finally { + // Dispose writer in finally block to avoid memory leaks + writer.dispose(); + } + +For more advanced usage, and information on how to use the ImageIO API, I suggest you read the +[Java Image I/O API Guide](http://docs.oracle.com/javase/7/docs/technotes/guides/imageio/spec/imageio_guideTOC.fm.html) +from Oracle. + + +#### Deploying the plugins in a web app + +Because the `ImageIO` plugin registry (the `IIORegistry`) is "VM global", it doesn't by default work well with +servlet contexts. This is especially evident if you load plugins from the `WEB-INF/lib` or `classes` folder. +Unless you add `ImageIO.scanForPlugins()` somewhere in your code, the plugins might never be available at all. + +I addition, servlet contexts dynamically loads and unloads classes (using a new class loader per context). +If you restart your application, old classes will by default remain in memory forever (because the next time +`scanForPlugins` is called, it's another `ClassLoader` that scans/loads classes, and thus they will be new instances +in the registry). If a read is attempted using one of the remaining ("old") readers, weird exceptions +(like `NullPointerException`s when accessing `static final` initialized fields) may occur. + +To work around both the discovery problem and the resource leak, +it is recommended to use the `IIOProviderContextListener` that implements +dynamic loading and unloading of ImageIO plugins for web applications. + + + + ... + + + ImageIO service provider loader/unloader + com.twelvemonkeys.servlet.image.IIOProviderContextListener + + + ... + + + + +#### Using the ResampleOp + +The library comes with a resampling (image resizing) operation, that contains many different algorithms +to provide excellent results at reasonable speed. + + import com.twelvemonkeys.image.ResampleOp; + + ... + + BufferedImage input = ...; // Image to resample + int width, height = ...; // new width/height + + BufferedImageOp resampler = new ResampleOp(width, height, ResampleOp.FILTER_LANCZOS); // A good default filter, see class documentation for more info + BufferedImage output = resampler.filter(input, null); + + +#### Using the DiffusionDither + +The library comes with a dithering operation, that can be used to convert `BufferedImage`s to `IndexColorModel` using +Floyd-Steinberg error-diffusion dither. + + import com.twelvemonkeys.image.DiffusionDither; + + ... + + BufferedImage input = ...; // Image to dither + + BufferedImageOp ditherer = new DiffusionDither(); + BufferedImage output = ditherer.filter(input, null); + + +## Building + +Download the project (using [Git](http://git-scm.com/downloads)): + + $ git clone git@github.com:haraldk/TwelveMonkeys.git + +This should create a folder named `TwelveMonkeys` in your current directory. Change directory to the `TwelveMonkeys` +folder, and issue the command below to build. + +Build the project (using [Maven](http://maven.apache.org/download.cgi)): + + $ mvn package + +Because the unit tests needs quite a bit of memory to run, you might have to set the environment variable `MAVEN_OPTS` +to give the Java process that runs Maven more memory.

See the Install section above. + + +q: What changes do I have to make to my code in order to use the plug-ins? + +a: The short answer is: None. For basic usage, like ImageIO.read(...) or ImageIO.getImageReaders(...), there is no need +to change your code. Most of the functionality is available through standard ImageIO APIs, and great care has been taken + not to introduce extra API where none is necessary. + +Should you want to use very specific/advanced features of some of the formats, you might have to use specific APIs, like + setting base URL for an SVG image that consists of multiple files, + or controlling the output compression of a TIFF file. + + +q: How does it work? + +a: The TwelveMonkeys ImageIO project contains plug-ins for ImageIO. + +ImageIO uses a service lookup mechanism, to discover plug-ins at runtime. + +TODO: Describe SPI mechanism. + +All you have have to do, is to make sure you have the TwelveMonkeys JARs in your classpath. + +The fine print: The TwelveMonkeys service providers for TIFF and JPEG overrides the onRegistration method, and +utilizes the pairwise partial ordering mechanism of the IIOServiceRegistry to make sure it is installed before +the Sun/Oracle provided JPEGImageReader and the Apple provided TIFFImageReader on OS X, respectively. +Using the pairwise ordering will not remove any functionality form these implementations, but in most cases you'll end +up using the TwelveMonkeys plug-ins instead. + + +q: What about JAI? Several of the formats are already supported by JAI. + +a: While JAI (and jai-imageio in particular) have support for some of the formats, JAI has some major issues. +The most obvious being: +- It's not actively developed. No issues has been fixed for years. +- To get full format support, you need native libs. +Native libs does not exist for several popular platforms/architectures, and further the native libs are not open source. +Some environments may also prevent deployment of native libs, which brings us back to square one. + + +q: What about JMagick or IM4Java? Can't you just use what´s already available? + +a: While great libraries with a wide range of formats support, the ImageMagick-based libraries has some disadvantages +compared to ImageIO. +- No real stream support, these libraries only work with files. +- No easy access to pixel data through standard Java2D/BufferedImage API. +- Not a pure Java solution, requires system specific native libs. + + +----- + +We did it diff --git a/common/common-image/src/main/java/com/twelvemonkeys/image/BrightnessContrastFilter.java b/common/common-image/src/main/java/com/twelvemonkeys/image/BrightnessContrastFilter.java index 2b4fb736..0dbb7598 100755 --- a/common/common-image/src/main/java/com/twelvemonkeys/image/BrightnessContrastFilter.java +++ b/common/common-image/src/main/java/com/twelvemonkeys/image/BrightnessContrastFilter.java @@ -60,6 +60,8 @@ import java.awt.image.RGBImageFilter; public class BrightnessContrastFilter extends RGBImageFilter { + // TODO: Replace with RescaleOp? + // This filter can filter IndexColorModel, as it is does not depend on // the pixels' location { diff --git a/common/common-image/src/main/java/com/twelvemonkeys/image/DiffusionDither.java b/common/common-image/src/main/java/com/twelvemonkeys/image/DiffusionDither.java index 48664fcc..d530d077 100755 --- a/common/common-image/src/main/java/com/twelvemonkeys/image/DiffusionDither.java +++ b/common/common-image/src/main/java/com/twelvemonkeys/image/DiffusionDither.java @@ -17,7 +17,7 @@ import java.util.Random; * This {@code BufferedImageOp/RasterOp} implements basic * Floyd-Steinberg error-diffusion algorithm for dithering. *
