Hey people, has anyone come across any articles or information that allows the use of the line or circle command that draws to the screen accurately accoding the known dot resolution?
Let me explain Say you have a maximum screen of 1280w800h, and a window#1 of 1280x800x0x0 Using a SCALE command of 800,0,0 allows drawing a line from 0 to 768 that reaches from the bottom to the top accurately but the x value is way off screen drawing to 1280 I have my own formulae for an x multiplication factor that seems to work well making squares appear square on the screen and circles appear circular on the screen as well, but not being a mathematics person my formulae is not very scientific and I have yet to check it on larger screens where any errors would be magnified. It seems however to work on standard QL screen of 512x256 well. I was just wondering before I explore any further if anyone else had writen anything on it or if anyone had any comments?
