When you're drawing a circle with something like the midpoint circle algorithm (which it sounds like Bill might be using), you typically just draw one octant, and then mirror the curve 8 times. Let's say the center of your circle is (x, y), and the point you want to mirror is at (x + dx, y + d). The full collection of 8 mirrored points are:
 (x + dx, y + dy), 
 (x + dy, y + dx), 
 (x + dx, y - dy), 
 (x + dy, y - dx), 
 (x - dx, y + dy), 
 (x - dy, y + dx), 
 (x - dy, y - dx), and
 (x - dx, y - dy).
 The trick to a RoundRect is to move the centers of those reflections to the four corners, offset inward by radius r. If my rectangle goes from (x0, y0) to (x1, y1) and my radius is r, I have four imaginary "inner corners" at (x0 + r, y0 +r) and (x1 - r, y1 - r). (Assume x0 < x1 and y0 < y1.) So now my 8 mirrors become:
 (x1 - r + dx, y1 - r + dy),
 (x1 - r + dy, y1 - r + dx),
 (x1 - r + dx, y0 + r - dy),
 (x1 - r + dy, y0 + r - dx),
 (x0 + r - dx, y1 - r + dy),
 (x0 + r - dy, y1 - r + dx),
 (x0 + r - dy, y0 + r - dx), and
 (x0 + r - dx, y0 + r - dy). 
 The cost of drawing a RoundRect should be little more than the cost of drawing the circle of radius r and the original rectangle. http://www.folklore.org/StoryView.py?project=Macintosh&story=Round_Rects_Are_Everywhere.txt&showcomments=1#comments Steve Jobs' comment at the end rings differently In light of the Walter Isaacson book revealing how often Jobs himself teared up and cried. http://www.folklore.org/StoryView.py?project=Macintosh&story=Leave_Of_Absence.txt&showcomments=1#comments It has been many years since this article, and the next latest comment. I was a young engineer in 1984, just out of college, and after playing around with a Mac at a local computer store I decided that I was going to buy one. They were running a special, bundling an ImageWriter with the Mac for $2495, a price that my girlfriend and I saw as astronomical. I was making a salary of $23K at the time, and we realized that we had to take out a bank loan for the computer. The banker nearly laughed at us, and asked if we had any collateral. We finally got a loan, and I spent my spare time learning to program the incredible machine in various languages such as Pascal, FORTH, and Assembler. This experience eventually landed my a hardware/software job developing products for the entire Macintosh line (which by then included the SE and MacII). Today, I am typing this note on my Mac Studio with 64GB of memory, and the machine cost me just about the same amount of 2023 money ($2600). My career wouldn't have been the same if I had not taken the chance of buying that "expensive" Mac in 1984. Macintosh forever! http://www.folklore.org/StoryView.py?project=Macintosh&story=Price_Fight.txt&showcomments=1#comments Does anyone know what happened to that demo disk? Is there a disk image file of it somewhere? Were any copies of the disk made? Perhaps it's still sitting on a shelf in Apple's archives? Someone did eventually create a replica of the demo, (https://macintoshgarden.org/apps/mac-intro-replica) but for the sake of software preservation it would be nice to have a copy of the original. http://www.folklore.org/StoryView.py?project=Macintosh&story=Intro_Demo.txt&showcomments=1#comments Here is more about the Andy Warhol story: https://www.vintag.es/2022/10/steve-jobs-showing-off-macintosh.html http://www.folklore.org/StoryView.py?project=Macintosh&story=A_Mac_For_Mick.txt&showcomments=1#comments I liked the comment above and thought it would be nice to mark it's ten year anniversary by commenting ^__^ http://www.folklore.org/StoryView.py?project=Macintosh&story=Rosings_Rascals.txt&showcomments=1#comments a weird glitch seem to have happened to images in some of the stories, here's the correct url for the one just above: https://www.folklore.org/images/Macintosh/bicycle.gif http://www.folklore.org/StoryView.py?project=Macintosh&story=Whats_A_Megaflop?.txt&showcomments=1#comments here's the correct urls of the broken images: https://www.folklore.org/images/Macintosh/moritz_84.jpg https://www.folklore.org/images/Macintosh/little_kingdom.jpg http://www.folklore.org/StoryView.py?project=Macintosh&story=The_Little_Kingdom.txt&showcomments=1#comments these are such fantastic tales, thanks Andy! here's the correct link to see the broken image: https://www.folklore.org/images/Macintosh/us2.jpg http://www.folklore.org/StoryView.py?project=Macintosh&story=US_Festival.txt&showcomments=1#comments
