A client is planning to purchase some soft fonts for a PostScript printer (Qume ScripTen). The supplier (who knows it all, of course :-) says that as the fonts are for a Mac, they cannot be downloaded from an IBM PClone. The supplier _says_ that they have tried copying the fonts from a Mac to a PC, and then downloading, and it didn't work. My client is, however, about 500 miles away and I do not want to have to travel there just to see whether or not this will be a problem. Is this feasable? (That the font can be downloaded from a Mac and not a PC). If so, is there anything that I can do for them, like converting from Mac format to PC format? Has anyone done anything like this before? As I understand it, a PostScript font is merely a PS program that describes the shape of the characters. Presumably there is some sort of encrypting process, so that fonts don't get modified and stolen and so on. Is this correct, or likely? Any replies (e-mail or posting) would be much appreciated. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Paul Nash Flagship Wide Area Networks (Pty) Ltd paul@frcs.UUCP ...!ddsw1!proxima!frcs!paul

If so, is there anything that I can do for them, like It depends. Adobe fonts do come in 2 flavors. A PC flavor and a MAC flavor. Why this was done beats me. At anyrate, rather than being a straight text file on the MAC, the file is broken up into blocks of data, each of which has a header. I suspect that this was done to make it difficult for a MAC font to be used on anything other than a MAC, but that is just conjecture. At anyrate, there is a document over on the Adobe file server, that deals with this problem. I believe it is something like "supporting downloaded fonts". It details the format of the font file for both the MAC and PC. Now, all the PC fonts that I've seen have been plain jane ascii fonts. It should be fairly easy to let the MAC do all the work, but using the font downloader (send ps I think) and let it parse out the font. Then perhaps use the cmd K to get it captured to a file as a true ascii font. For other peoples fonts, I don't think there is a problem. At least Cassidy and Greene, and Century Software fonts are straight ASCII files. > As I understand it, a PostScript font is merely a PS program that > describes the shape of the characters.

>>>There is a Mac program called unAdobe which will convert the Mac >>>format into a standard ASCII file, which you could then send from >>>any computer (UNIX, PCs, etc.) Impressive. I obtained good results the following way: - create a document using the desired fonts; - create a PostScript file using the Apple/F key in the print dialog; - cut the font descriptions out of the PostScript file. Easy.

Sorry Woody, my PC fonts arrived in binary form, and I had to
use Adobe's downloader to decrypt them. I used my Sun 386i DOS
window to capture the ASCII output to a file. Once I had more
time, I wrote a program to decrypt the Adobe binary format.
