[ ... ] I've got a better idea: NAPLPS. QuickDraw is a crock. QuickDraw is also Apple's puppy, and any attempt to clone it will get you sued real fast. Further, to get any details on QuickDraw or PICT format, you have to buy the _Inside Macintosh_ books, which aren't cheap. QuickDraw is standard only with respect to Apple's line of "computers", and nowhere else. On the other hand, NAPLPS will address every need for portable structured graphics you'll ever need. NAPLPS will work on CRT's or paper. NAPLPS is resolution independent, which means your drawings can be rendered at 320 x 200, or 640 x 400 overscan, or on a 3' x 6' chart at 600 dpi, and it will come out looking correct. NAPLPS is also system-independent. NAPLPS readers and writers exist for a wide variety of computer systems, including those with vector-based output devices. What's more, NAPLPS is public domain. It also happens to be an established and registered standard. You can obtain a copy of the standard for $25 from ANSI, I believe. This document will tell you everything you need to know to read and write NAPLPS files. Also, you can obtain test files to see if your reader is working correctly. There are also a number of NAPLPS bulletin boards which you can use to test your software (Prodigy isn't one of them). In short, if you want to do portable structured graphics, QuickDraw is not the way to go. It's proprietary, and far from general. You should at least look at what NAPLPS can offer you.
