Yeah, there it goes: PS: It works on PowerPCs, not on intel, the rectangles a normal, not rounded.

Somewhere I created a category to extend NSBezierPath

@implementation NSBezierPath (RoundedRectCategory) + (NSBezierPath *) bezierPathWithRoundRectInRect:(NSRect)rect radius: (float) radius { NSBezierPath *path; NSRect inner_rect;

	inner_rect = NSInsetRect(rect, radius, radius);

path = [NSBezierPath bezierPath]; [path moveToPoint:NSMakePoint(rect.origin.x+rect.size.width/2.0, rect.origin.y+rect.size.height)];

[path appendBezierPathWithArcWithCenter:NSMakePoint (inner_rect.origin.x, inner_rect.origin.y + inner_rect.size.height) radius: radius startAngle: 90.0 endAngle: 180.0];

[path appendBezierPathWithArcWithCenter:inner_rect.origin radius: radius startAngle: 180.0 endAngle:270.0];

[path appendBezierPathWithArcWithCenter:NSMakePoint (inner_rect.origin.x + inner_rect.size.width, inner_rect.origin.y) radius: radius startAngle: 270.0 endAngle:360.0];

[path appendBezierPathWithArcWithCenter:NSMakePoint (inner_rect.origin.x + inner_rect.size.width, inner_rect.origin.y + inner_rect.size.height) radius: radius startAngle: 0.0 endAngle:90.0]; [path closePath];

	return path;
}


@end

Somewhere else, i draw a rectangle onto an nsimage

NSImage *imageRoundRect( NSColor *backgroundColor, NSColor *strokeColor, NSSize size, float roundCornerRadius ) { if( backgroundColor == nil || strokeColor == nil || NSEqualSizes ( size, NSZeroSize ) ) return nil; NSRect frame; frame.origin = NSZeroPoint; frame.size = size; frame = NSInsetRect( frame, 1.0, 1.0 ); if( (roundCornerRadius * 2.0) > frame.size.height ) roundCornerRadius = frame.size.height / 2.0; if( (roundCornerRadius * 2.0) > frame.size.width ) roundCornerRadius = frame.size.width / 2.0; NSImage *newImage = [ [ NSImage alloc ] initWithSize: size ]; [ newImage setBackgroundColor: [ NSColor clearColor ] ]; [ newImage lockFocus ]; // Drawing the image NSBezierPath *p = [ NSBezierPath bezierPathWithRoundRectInRect: frame radius: roundCornerRadius ]; [ backgroundColor setFill ]; [ p fill ]; [ strokeColor setStroke ]; [ p stroke ]; [ newImage unlockFocus ]; return [ newImage autorelease ]; }

Can you post the code *you* use specifically to draw the path?

Hi All,
I'm currently drawing a round rectangle with arcs. When drawing direclty to the screen, I get round rectangles. When I lock the focus on an nsimage, the rectanlges aren't rounded, but this only happens on intel macs, powerpc macs have no problem.
	I use the code that comes from this page:
