In particular, Word for Windows on the PC I made some modifications to a program called "xv".... One of the mods enables xv to output an eps file... The process isn't especially streamlined, but here's how I do it: 1) use a postscript interpreter to get the postscript image rendered onto the screen of my Sun workstation (I use "pageview", an OpenWindows utility)... 2) Capture the rendered postscript from the Sun's screen into a rasterfile (I use "snapshot", another OpenWindows utility)... 3) Read in the rasterfile and output the EPS file using "xv"... I have found that I usually have to crop the image, and I also have to edit the colormap... The problem is that although the EPS spec will permit a "gray-scale" image, most programs that I have seen that use the preview portion of the EPS only can handle a bitmap... So, you have to tell "xv" which colors you want mapped to black and which colors you want mapped to white... Same is true for gray scale images... I guess I could have written code that would have picked the color -> black/white mapping automatically, but it probably wouldn't map it the way the user really wanted it mapped... 4) the output of xv is an EPS file with a bitmap (i.e. black-and-white) preview section, followed by a postscript "image".... The final step is to discard the postscript image, and replace it with the original postscript file... I'm not partial to having to go through 4 steps to make an EPS file... If someone has a better way of doing this, I'd like to hear it... I'd be glad to give out my modified version of "xv".... I sent the changes to the author of xv (John Bradley - bradley@cis.upenn.edu), but he's working on making xv into a commercial product so I'm not sure if/when he's gonna publish another release of xv....
