nsbezierpath

If i have a NSBezierPath object , is there a way to get co-ordinates(x,y) of all the points drawn. I want to move a NSRect along the path. An NSBezierPath doesn't define exactly which points it draws in, but it does contain the points needed to define its pieces. You can use the elementAtIndex:associatedPoints: method to get the points for each vector element in the path. To get each point in the path you would have to iterate over all of the elements and get the associated points. For straight lines, this method will give you the endpoint, but if you keep track of the previous point you can

I am making a custom NSView object that has some content that changes often, and some that changes much more infrequently. As it would turn out, the parts that change less often take the most time to draw. What I would like to do is render these two parts in different layers, so that I can update one or the other separately, thus sparing my user a sluggish user interface. How might I go about doing this? I have not found many good tutorials on this sort of thing, and none that talk about rendering NSBezierPaths on a CALayer. Ideas anyone? Your hunch is right, this is actually an excellent way

I am creating a NSView subclass that has rounded corners. This view is meant to be a container and other subviews will be added to it. I am trying to get the rounded corners of the NSView to clip all of the subview's corners as well, but am not able to get it. - (void)drawRect:(NSRect)dirtyRect { NSRect rect = [self bounds]; NSBezierPath *path = [NSBezierPath bezierPathWithRoundedRect:rect xRadius:self.radius yRadius:self.radius]; [path addClip]; [[NSColor redColor] set]; NSRectFill(dirtyRect); [super drawRect:dirtyRect]; } The red is just for example. If I add a subview to the rect, The

I am trying to import paths from a vector drawing program into the ios environment. I would like to get them into CGpaths or UIbezierpaths. I am most interested in importing paths from adobe illustrator. The best way seems to save as an svg and then import. I have found some resources for parsing exported SVG files that describe the paths. However, everything I have found only deals with absolute paths and not relative paths. The path below has capital C's and lowercase C's. I know how to parse the capital C (absolute paths) but I have no idea how to parse the lowercase c's (relative paths) I

I am trying to make a NSScrollView with clipped corners, similar to the Twitter app: I have a NSScrollView subclass which I added the following code: - (void)drawRect:(NSRect)dirtyRect { NSBezierPath *pcath = [NSBezierPath bezierPathWithRoundedRect:[self bounds] xRadius:kDefaultCornerRadius yRadius:kDefaultCornerRadius]; [path setClip]; [super drawRect:dirtyRect]; } I expected the content of the NSScrollView to have rounded corners, but it is not respecting the clipped path. How can I do this? UPDATE & CLARIFICATION I know how to make a custom NSScroller , I know how to make it transparent

I would like to animate a straight line curving into a bezier curve (from "_" to "n"), is there a library somewhere that can help me to do it ? I know how to draw a Bezier curve with UIBezierPath, I could redraw rapidly and progressively do the transformation, but if something already does that it would be cool :-) I might do something with a CADisplayLink . For example, you could do this in your view controller using a CAShapeLayer , e.g.: #import "ViewController.h" #import <QuartzCore/QuartzCore.h> @interface ViewController () @property (nonatomic) CFTimeInterval firstTimestamp; @property

I want to do a rounded rectangle outline on an NSImage and I figured that using NSBezierPath would be the best way. However, I ran into a problem: instead of drawing a nice curve, I get this: For reasons I can't understand, NSBezierPath is drawing the rounded part with a darker color than the rest. Here's the code I'm using (inside a drawRect: call on a custom view): NSBezierPath* bp = [NSBezierPath bezierPathWithRoundedRect: self.bounds xRadius: 5 yRadius: 5]; [[[NSColor blackColor] colorWithAlphaComponent: 0.5] setStroke]; [bp stroke]; Any ideas? Edit: If I inset the path by 0.5 everything
