Download and Build StaticImage

Click here to download StaticImage. and its CMakeLists.txt file.

Once the tarball StaticImage.tar has been downloaded and extracted,

cd StaticImage/build 

• If VTK is installed:

cmake ..

• If VTK is not installed but compiled on your system, you will need to specify the path to your VTK build:

cmake -DVTK_DIR:PATH=/home/me/vtk_build ..

Build the project:

make

and run it:

./StaticImage

WINDOWS USERS PLEASE NOTE: Be sure to add the VTK bin directory to your path. This will resolve the VTK dll's at run time.
