QImageToImageSource
VTKExamples/Cxx/Qt/QImageToImageSource
Description¶
This example demonstrates the use of vtkQImageToImageSource.
See also the ImageDataToQImage example.
Code¶
QImageToImageSource.cxx
#include <QApplication> #include <QPixmap> #include "vtkSmartPointer.h" #include "vtkQImageToImageSource.h" int main(int argc, char *argv[]) { QApplication app(argc, argv); QPixmap pixmap(10,10); QColor color(10,20,30); pixmap.fill(color); vtkSmartPointer<vtkQImageToImageSource> qimageToImageSource = vtkSmartPointer<vtkQImageToImageSource>::New(); QImage qimage = pixmap.toImage(); qimageToImageSource->SetQImage(&qimage); qimageToImageSource->Update(); // vtkImageData* image = qimageToImageSource->GetOutput(); return EXIT_SUCCESS; }
CMakeLists.txt¶
cmake_minimum_required(VERSION 2.8) PROJECT(QImageToImageSource) find_package(VTK REQUIRED) include(${VTK_USE_FILE}) add_executable(QImageToImageSource MACOSX_BUNDLE QImageToImageSource.cxx) target_link_libraries(QImageToImageSource ${VTK_LIBRARIES})
Download and Build QImageToImageSource¶
Danger
The generation of tar files has not been ported to the new VTKExamples. Some tarballs may be missing or out-of-date.
Click here to download QImageToImageSource and its CMakeLists.txt file. Once the tarball QImageToImageSource.tar has been downloaded and extracted,
cd QImageToImageSource/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:
./QImageToImageSource
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.
