ubuntu下VTK显示.jpg格式图片的简单例子

一、前提
    VTK安装完毕
二、创建
建立文件夹：mkdir jpgexample
cd jpgexample
vi jpg.cxx
code:
 1 #include "vtkQuadraticHexahedron.h"
  2 #include "vtkUnstructuredGridReader.h"
  3 #include "vtkMapper.h"
  4 #include "vtkBMPReader.h"
  5 #include "vtkTexture.h"
  6 #include "vtkUnstructuredGridSource.h"
  7 #include "vtkUnstructuredGrid.h"
  8 #include "vtkProperty.h"
  9 #include "vtkDataSetMapper.h"
 10 #include "vtkLight.h"
 11 #include "vtkCamera.h"
 12 #include "vtkUnstructuredGridWriter.h"
 13 #include "vtkPolyDataMapper.h"
 14 #include "vtkActor.h"
 15 #include "vtkRenderWindow.h"
 16 #include "vtkRenderer.h"
 17 #include "vtkRenderWindowInteractor.h"
 18 #include "vtkInteractorStyleTrackballCamera.h"
 19 #include "vtkCallbackCommand.h"
 20 #include "vtkCamera.h"
 21
 22 #include "vtkJPEGReader.h"
 23 #include "vtkInteractorStyleImage.h"
 24 #include "vtkImageActor.h"
 25
 26 #define EXAMPLE_FILE "/home/Pictures/*.jpg"
 27
 28 int main(int argc, char **argv)
 29 {
 30
 31  vtkJPEGReader *m_reader = vtkJPEGReader::New();
 32  m_reader->SetFileName(EXAMPLE_FILE);
 33
 34  vtkImageActor *m_Actor = vtkImageActor::New();
 35  m_Actor->SetInput(m_reader->GetOutput());
 36
 37  vtkRenderer *m_Renderer = vtkRenderer::New();
 38  m_Renderer->AddActor(m_Actor);
 39
 40  vtkRenderWindow *m_RenWin = vtkRenderWindow::New();
 41  m_RenWin->AddRenderer(m_Renderer);

 42  m_RenWin->SetSize(800, 800);
 43
 44  vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::New();
 45  iren->SetRenderWindow(m_RenWin);
 46
 47  iren->Initialize();
 48  iren->Start();
 49
 50  m_reader->Delete();
 51  m_Actor->Delete();
 52  m_Renderer->Delete();
 53  m_RenWin->Delete();
 54  iren->Delete();
 55  return 0;
 56 }


vi CMakeLists.txt
code:
  1 PROJECT (Step1)
  2
  3 IF(NOT VTK_BINARY_DIR)
  4 FIND_PACKAGE(VTK REQUIRED)
  5 IF(NOT VTK_USE_RENDERING)
  6   MESSAGE(FATAL_ERROR "Example ${PROJECT_NAME} requires VTK_USE_RENDERING.")
  7 ENDIF(NOT VTK_USE_RENDERING)
  8 INCLUDE(${VTK_USE_FILE})
  9 ENDIF(NOT VTK_BINARY_DIR)
 10
 11 ADD_EXECUTABLE(Jpg jpg.cxx)
 12 TARGET_LINK_LIBRARIES(Jpg vtkRendering)


三、编译
ccmake  ./
cmake ./
make

./Jpg
