VolViewerOMERO

Overview

It is possible to build VolViewer with support for reading images directly from an OMERO server. The viewer can read XYZC image stacks with up to 3 channels (C). Minimal metadata such as the image dimensions, physical voxel size and channel min/max threshold values are also supported. Currently the viewer supports the following OMERO data types: uint8, uint16, int8, int16.

For the exact C++ implementations of the OMERO loader please refer to the h / cpp files from the SVN.

Requirements

To build VolViewer with OMERO support you will require the following:

• An SVN client, to check out the VolViewer source code, such as TortoiseSVN for windows or svn for linux/mac.
• The latest Qt SDK.
• The OMERO cpp libraries.

How To

• Start by checking out the latest VolViewer source code from the SVN:
  • VolViewer SVN
• Next build the OMERO cpp libraries following this guide:
  • OMERO cpp libraries
  • Note to build the OMERO cpp you will require the ICE libraries. Note that these exist in binary form for Windows, Mac and Linux. You should only use version 3.3.1 of ICE.
• Now that you have the OMERO cpp library built you are ready to build VolViewer with OMERO support. VolViewer is built using qmake so it is relatively straight forward.
  • Start by enabling the OMERO support in the source code by editing the MyDefines.h file by un-commenting the line:

//#define OMERO_SUPPORT

becomes

#define OMERO_SUPPORT

• • Next we turn on OMERO support in the scr.pro project file by adding omero in the config variable:

CONFIG += qt thread x86_64

becomes

CONFIG += qt thread x86_64 omero

• • Lastly we are now ready to run the qmake command. You will require to set the environment variables for ICE_HOME and OMERO_HOME.
    • Example build scripts can be found for:
      • Windows
      • Mac OS X
      • Linux
      • Note that there is also a support for a Visual Studio 2010 project for windows found here.
