Overview
ImageJ plugin for reading and writing HDF5 files.
This project originated from and is inspired by: ImageJ HDF Plugin of Matthias Schlachter Chair of Pattern Recognition and Image Processing, University of Freiburg, Germany. https://code.google.com/p/imagej-hdf/
Usage
To open a HDF5 file use:
File > Import > HDF5...
To save to an HDF5 file use:
File > SaveAs > HDF5
Installation
To be able to install this plugin ImageJ need to be run with a Java 7 or greater JVM.
-
Download latest HDF5 ImageJ plugin from here.
-
Go into the ImageJ installation folder and extract the downloaded zip.
cd <IMAGEJ_HOME>
unzip <path of downloaded zip>
Configuration (Optional)
If you want to configure the HDF5 Reader as a standard file reader you need to register the reader within the HandleExtraFileTypes.java
file.
This can be done as follows (details on this can be found on: http://albert.rierol.net/imagej_programming_tutorials.html):
- Add
HandleExtraFileTypes.java
if (name.endsWith(".h5") || name.endsWith(".hdf5")) {
return tryPlugIn("ch.psi.imagej.hdf5.HDF5Reader", path);
}
- Recompile
HandleExtraFileTypes.java
javac -classpath ij.jar ./plugins/Input-Output/HandleExtraFileTypes.java
Usage
Mac OS X
java -Djava.library.path=./lib/mac64 -Xmx3048m -jar ImageJ64.app/Contents/Resources/Java/ij.jar
Linux
java -Djava.library.path=./lib/linux64 -Xmx3048m -jar ij.jar
The Xmx
setting is quite random it depends on how big hdf5 files you are planning to open.
Fiji
Fiji currently comes with Java 6 bundled. As the HDF5 Plugin requires Java 7 or higher we have to instruct Fiji to use an alternative Java. This can be done as follows:
cd <FIJI_HOME>
<fiji> --java-home /usr/lib/jvm/jre-1.7.0-openjdk.x86_64 -Djava.library.path=lib/linux64
Starting with Java 8 just the LD_LIBRARY_PATH variable need to be set. For MacOSX it is export DYLD_LIBRARY_PATH=lib/mac64/:$DYLD_LIBRARY_PATH
.
Development
To create an all in one zip file for installation in a ImageJ installation use:
mvn clean compile assembly:assembly
The zip file contains an all in one jar as well as the required native libraries for Windows, Linux and Mac OS X.
