[vtkusers] how to render a bitmap file

[Paul Cochrane]

Try something like the following:  (python code, will convert to C++/Tcl/Java 
quite easily)

import vtk
# define the renderer and the render window
ren = vtk.vtkRenderer()
renWin = vtk.vtkRenderWindow()
renWin.AddRenderer(ren)
# use an interactive render window
iren = vtk.vtkRenderWindowInteractor()
iren.SetRenderWindow(renWin)

# set up the actor for the image
imgActor = vtk.vtkImageActor()

# read the bmp file
bmpReader = vtk.vtkBMPReader()
bmpReader.SetFileName("file.bmp")
imgActor.SetInput(bmpReader.GetOutput())

# add the actor to the renderer, add some settings to the render window
ren.AddActor(imgActor)
renWin.SetSize(400,400)
ren.SetBackground(0.1,0.2,0.4)

# render it!
iren.Initialize()
renWin.Render()
iren.Start()
