Degas to Postscript: I handle this problem on a regular basis using the following tools: 1). Import the Degas picture into TOUCHUP and get rid of the jaggies. This step is needed for images that are to appear large on the final page. It is not needed for small things like logos. The procedure generally works only for line art. I have not yet tried it with DEGAS pictures derived from continous tone sources (VIDI ST or Computereyes). 2). Save the result as an .IMG file. 3). Import it into Timeworks' Publisher ST. This must be installed using The Postscript option. PageStream may also work, but I am not sure of this. 4). Print the file as Postscript. Publisher ST saves the result as a disk file containing Postscript commands. 5). Image it out using an SLM804 with Ultrascript. It may be possible to print the file using a printer with built-in postscript. I have just never tried this option. This is admittedly a high-priced solution, but not outrageously so. I certainly get the job done more quickly than if I tried to mess around with writing my own code for this. It should also be noted that PicTeX is another way to get hardcopy from an image file. Since this is an open software environment it should not be too difficult to write a program to convert Degas to PicTeX. PicTeX is available on the Current Notes TeX distribution kit. While we are on this subject I would like to respond to Dylan Yolles on the matter of TeX DVI to Postscript conversion. With my imperfect knowledge of the subject it appeasr that such a conversion would not make sense. The font files used to generate the DVI document in TeX do not correspond in any sense to those used in Postscript. It is therefore unreasonable to expect that the layout of the document would be preserved in such a conversion. The basic function of a DVI***.TTP program is to bit map the text for output to a device that supports some sort of raster. Even if we assumed that a psosctript printer could be trained to do this it would seem like horribly inefficient use of postscript. My experience in beta-testing the TeX distribution put together by Horace MItchell for Current Notes is that it is best to stay in the TeX environment once you are in it. The SLM804 is an outstanding output device and the software runs with satisfying speed on a 1 meg or larger Atari ST. We currently lack a DVI driver for a 24 pin printer, which would make TeX much more affordable and accessible. I am not sure what Dyllan's application is, but if he would care to share it with us maybe we can find another way to solve his problem. One final thought: Maybe the TeX for the Macintosh would run under Spectre GCR and produce Postscript output. Has anyone tried this?

Of course, I am talking about a sun system... but we use dvi2ps constantly.... -- ----------------------------------------------------------------------------- Scott D.
