vtkPPMWRITE Procedure
Writes the contents of a VTK window to a PPM file.
Usage
vtkPPMWRITE[, window_index]
Input Parameters
window_index—(optional) An integer specifying the index of an existing VTK window. If omitted, the current window is used.
Keywords
Filename—File path to store PPM file. (Default: 'wave.ppm')
Discussion
This procedure saves a snapshot of the selected window as a PPM file. It is important to make sure the VTK window fully visible when this routine is called because an obscuring portion of another window will be captured as part of the image. This is a limitation of VTK.
Example 1
Writing a PPM file.
vtkwindow, 1
vtkaxes
vtkPPMWRITE, 1
Example 2
Writing the PPM file to the file name of PV.ppm.
vtkwindow, 2, background='blue'
vtkPPMWRITE, 2, filename='PV.ppm'
