# NVIZ Reference Manual

CONTENTS

## Image Dump

Image Dump saves the contents of the current NVIZ viewer to an image file. Make sure the NVIZ viewer is on top of all other windows in the current workspace. If any windows cover the NVIZ viewer, they appear as part of the saved image. With the exception of the Max. Resolution PPM, the image has the same dimensions as the NVIZ viewer.

IRIS RGB Image
  Saves the scene to an Iris RGB image file.
PPM Image
  Saves the scene to a PPM image file. You can convert a PPM image to a PNG image with the widely installed NetPBM tools.
  e.g.:
    `pnmtopng image.ppm > image.png`
TIFF Image
  Saves the scene to a TIFF image file.
Save Max. Resolution PPM(s)
  Saves the scene to the highest resolution (size) supported by the users graphics setup. The oversized image renders as a series of tiles that are automatically assembled by the program pnmcat . If pnmcat is not available, you need to manually assemble the tiles with another graphics program. The aspect ratio of the oversized image matches the aspect ratio of the original NVIZ viewer.
