With printed output from the Atoms or Spectra windows, you have a choice of using the full page, or confining the graphics output to a frame. For Raster Files and Metafiles [Windows] or PICT files [Macintosh] (File menu) output always goes to a frame. This applies either to the spectrum plot or to the atoms plot
In printed and pen-plot output, the frame can be positioned on the page; the offset gives the displacement of the upper left corner of the frame from the upper left corner of the page.
For Raster Files and Metafiles or PICT files you can choose the units for the size and offset of the window; either inches, centimeters or dots (pixels), and for Raster Files you can also specify the nominal dots per inch or centimeter.
The image is scaled to the frame in the way specified in the Spectra Plot Parameters or the Atoms Plot Parameters (Settings menu).
