[cl-gd-devel] just to share
by arry 23 Nov '05

I just want to share a problem with cl-gd or maybe gd itself i don't know... Has anybody tried to draw an ellipse which starts and ends at a precise angle? Well, I have and it turns out that the angles that i have specified are not drawn exact , they are either bigger or smaller and SOMETIMES theyy are correct! is this a problem with gd or cl-gd? example I draw an ellipse that passes through two points then I want this ellipse to start from exactly one of the two point aand end at the other one. I calculate the angles with tthe help of the function (atan) or (asin) using the coordinates of the center of the ellipse and the two given points... and the angles drawn don't match with the given points That's funny!!! ridiculous!!! There's always 1 or 2 maybe more degrees discrapency between the angles drawn and the given points Anybody encountered the same thing? __________________________________ Yahoo!

[cl-gd-devel] Antialiased lines, arcs ... don't work, even the test orig pic is wrong...
by arry 11 Nov '05

Hi I am using CL-GD for over a week now and found out that the antialiasing doesn't work at all... The test, I think was number 4, produces the same result as its orig picture in the orig folder, but the orig picture in the orig folder is also wrong - there's no antialiasing in it... And this orig pic comes from the package itself... The picture on the web though is correct here http://www.weitz.de/cl-gd/ the pic's name: is anti-aliased-lines.png I tested this with AlegroCL and CLISP both under windows... with the same results... Is this a bug? Thanks for the help arry __________________________________ Yahoo! Mail - PC Magazine Editors' Choice 2005 http://mail.yahoo.com
