The answer to the Piece-of-Pie shape is ...
moveToPoint:aPt... which locates/anchors the path.
Then to be able to draw in different colors, I need
...removeAllPoints and ... moveToPoint:aPt at the
end of each loop to avoid getting all the Pie shapes
in the color that was defined last in the loop.
float st = 1, num = 0, rr, gg, bb, y = 200,
ct = 0;
NSPoint aPt = {223, 223};
NSBezierPath *bp = [NSBezierPath bezierPath];
[bp moveToPoint:aPt];
do{
rr = num/255; gg = num/255; bb =
num/255;
[[NSColor colorWithCalibratedRed:rr
green:gg blue:bb
alpha:1.0] set];
[bp
appendBezierPathWithArcWithCenter:aPt radius:y
startAngle:108 endAngle:114];
[bp closePath];
[bp fill]; [bp removeAllPoints];
[bp
moveToPoint:aPt];
st++; y -= 10; ct += 16;
}while(ct<256);
...here's to all us newbies whose questions don't
always raise the interest of this brain trust.
Thanks
