Sabrina can write a PostScript (
.ps) file containing
the graphics on the screen. There are 2 types of graphics:
Dumpbutton on the PostScript Options Dialog or the
Post DUMPcommand, are made by copying the screen and may be requested after an image has been rendered. Raster
Dumpsmade from a color display will automatically give color plots on a color PostScript device and grayscale on a monochrome printer. An image dump will also reproduce any vector graphics, such as particle tracks, that are visible on the screen. Resolution, however, is usually improved by capturing the lines as actual PostScript vector commands.
Write PostScriptis checked (
Post ONcommand). When printed, vector graphics give higher resolution and a smoother appearance than if the elements were copied as raster graphics. Oblique lines, for example, will not show the jagged appearance caused by the finite bitmap resoution.
Dumpis made automatically following a ray traced Color, Etch, or 2-D Slice picture. Vector graphics operations are written as they are executed.
