Hard-Copy Drawings from DRAWxtl

There is no unique way to convert the 'pov' files into a form suitable for hard copy, or for inclusion into a Web site, etc. My preferred method is as follows:
  • In POV, select Anti-Aliasing On with an Antialiasing_Threshold of at least 0.3.
  • Perform the POV processing with at least 500 x 500 pixels. To be correct on the printed page, the ratio of horizontal to vertical pixel size should match the shape of pixels on your printer. For higher quality, the number of pixels can be increased at a cost of increased time for rendering and increased disk storage for the output file. Note: The aspect ratio of the drawing on the screen may be different than a VRML image because a screen pixel may not be square.
  • Process the POV output files with a graphics processing program, which can read the files, annotate them, print them on any system printer, convert them to other graphic formats, or import them into a word-processing document. For this step under Windows, I use Paint Shop Pro. A trial version is available. A downloadable alternative is the GNU Image Manipulation Program (GIMP), which is available for UNIX, Windows 98, ME, NT, 2000 or XP, and MacIntosh systems. These programs can convert an image from one format to another; resize, rotate, sharpen, color reduce, or add special effects to an image; create a framed thumbnail of an image; and many other functions.
