question about CDC:Pie
-
Hi I have a question regarding the pie method in CDC there are eight parms the first 4 represent the bounding rectangle in which the ellipse or the circle is enclosed the last 4 represent the starting and ending points and of the arc my question is for the last 4 why is the "Y' vertical parm necessary it would always seem to be from the center of the arc to its edge I hope my question makes sense thanks

"Y", the radius at x = 0, varies with the angle of the arc (as a point on the circumference).

Tell me if I am right I think I first need to determine the angle so if is 25 % then the angle is 90 4 / 360 then to get the y it’s y = consin(angle) x = sin(angle) Right ?

Thanks for help one more follow up question Would this equation not have to be multiplied by the number of pixels per circle degree I mean the formula is the same for big and small circles so you have to taken into account the size of the circle I’m sure I can do it with GetCientrect Thanks

The radius determines the size of a circle. If you want to scale, you vary the radius.
