how vtk do th zoom for jpeg reader and dicom reader

This is an example of a code of vtk to read a jpeg image http://www.vtk.org/Wiki/VTK/Examples/Cxx/IO/JPEGReader or dicom file http://www.vtk.org/Wiki/VTK/Examples/Cxx/IO/ReadDICOM , when I run these projects, i can zomm the image with the right button of the mouse however, in the code there is nothing in a direct relation with zoom or something like this, so there is something inside the classes can anyone tell me how vtk can do this zoom because i need it in another project ?

Solution

  • Yes, certainly there is code inside the other classes. vtkRenderWindow, vtkRenderWindowInteractor, and vtkRenderer are all referenced by that sample. You can trace down the zooming code through those. https://github.com/Kitware/VTK/tree/master/Rendering/Core
