VigraQt

This package contains Qt bindings for VIGRA, in particular for Qt version 4.x (with x>5). This includes:

• Header files (i.e. vigraqimage.hxx) for letting VIGRA algorithms work directly on Qt images (also applicable for Qt 5.x).
• An image viewer class (QImageViewer) that includes panning and zooming, a derived OverlayViewer class that adds overlay support and an OpenGL-based viewer (also applicable for Qt 5.x).
• A color map for displaying images or analysis results in false colors, including a Qt widget for interactively editing the color map (also applicable for Qt 5.x).
• Python bindings and a designer plugin for including the widgets in your own (C++ or Python-based) applications (for Qt 4.x only).

Installation

In contrast to earlier versions, starting with vigraqt4-0.4, the three components (the VigraQt library, the designer plugin, and the python bindings) are compiled and installed separately (the old, autotools-based build system was ditched, which accounts for the big difference in the download's filesizes..). This is not unlike with other, similar software packages (e.g. qwt) and probably makes sense:

• You don't have to care about the paths for Python or the designer plugins when you only want to use the VigraQt library, or even only its header files. It is likely that most users are not interested in all three components, and distributions would probably also want to create separate subpackages for dependency reasons.
• The install processes (especially the typical target directories) are quite different. This way, each subpackage can use the build tools best suited and the user can focus on installing the part he/she is currently interested in.

For the VigraQt library itself, use qmake:

qmake # optionally, add INSTALLBASE=/some/where
make
# copies the library and header files to subdirectores of
# INSTALLBASE (default: /usr/local):
make install

Similarly, you can install the designer plugin with:

cd src/designer-plugin
qmake
make
# copies the plugin into ${QT_PLUGINS}/designer
make install

Finally, the Python bindings require PyQt and use its python-based build system:

cd src/sip
# optionally, add -m /your/python/site-packages:
python configure.py
make
make install # installs VigraQt.so into the module target dir (see above)

Using CMake

Alternatively, you may use CMake for configuring the build, for instance:

mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release \
      -DCMAKE_INSTALL_PREFIX=$HOME/inst \
      -DPYTHON_SITE_PACKAGES_DIR=$HOME/inst/lib/python2.6/site-packages \
      ..
