Ok, thanks to all those who pointed out that ghostscript can emit pdf. I tried with a non-compressed ps output from dvips and size seems to remain about the same. it is fast, the only issue is the absence of compression. But that i will leave as an issue for those who are asking me for PDF instead of gzipped postscript :) > does not compress the output at all, except for character > bitmaps: it can't use LZW because of Unisys' patent > claims, and it doesn't yet use other compression methods > for images. actually, i saw some posting on the LZW patent mentioning that the non-us (europe) patent only refers to hardware implementations ... i'll try to dig it out and post it (maybe one can come out with non-us gs patches... similar to the crypto stuff...) Speaking of the opposite conversion (pdf->ps) that Jim mentioned: ghostscript is very slow at this and produces huge files (a pain when you have to print a page in the middle of a long document since it appears to scan the whole document at the same slow pace). Acroread also produces huge files, although it is quite slow as well (faster than ghostscript, but much slower than both during rendering -- this i don't understand, perhaps it is because it generates 16 times as much data because the resolution goes up from 72dpi to 300dpi ? (but when producing postscript it really shouldn't generate bitmaps!) Anyways... i get what i pay for, just wondering if the commercial version of the adobe tools are similarly slow. cheers luigi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
