Hello all,

I need help in converting color eps files to TIFF *with high resolution*, not just  
with 72dpi screen resolution.

Let me explain my problem in more detail: we can use a slide recorder (4000 lines  
resolution), which is unfortunately connected to a Mac IIfx. The only format it  
accepts is Mac PICT format. When I compose my presentation slide on the NeXT, all I  
end up with is a nice color eps file (I use Adobe3, with imported eps files from  
other machines [those files may contain pixel graphic from screen dumps], to compose  
the graphic part, then I use LaTeX to compose the page [with text and graphic],  
dvips makes a ps file out of the one page [even with the -E option it most often not  
able to produce eps, only ps], then I place this in a new Adobe file and give it an  
invisible surrounding box and save it as eps with all placements included).

Now I have a high res (I can choose a high custom resolution in dvips) color eps  
file. My problem is: I could not find an app which could transform this into a *high  
res* PICT file. Well, once I would have a high res TIFF file I would know how to  
convert that to high res PICT, but all the apps I tested (Scene, ImageViewer, Icon,  
Appsoft, Draw) that can convert to TIFF save the TIFF file with only 72dpi,  
presumably the screen resolution. And this is just not enough for the slide  
recorder. Also, the TeX test is very hard to read as parts of the characters are  
simply missing (e.g. the horizontal bar of a capital H).

I also looked into pbmplus, the utha raster toolkit, and the SDSC image conversion  
utilities but none could READ eps, only write it! I also looked into comp.graphics  
but didn't find anything in the FAQ lists. 

Here my question: is eps a one way road? Once eps, eps for ever? Everything on the  
NeXt is geared towards eps, but is there no way to convert it to something else  
*without loosing resolution* so that one could use output media available on other  
computers?

Please reply by e-mail or follow-up to comp.sys.next.misc

Thanks a lot,
