cocoa - How to draw a rounded NSImage -

-

I try to create an NSImage or NSImageCell with rounded corners I am doing a inside NSTableView . I can not get anything to work. The best part here is that my custom nscell : 

  - (zero) drawerwirewrightframe: (NSRact) frame Inview: (NSVUU) * Controlview (if (ThumbnailLink) {NSURL * url = [NSURL URLWithString: thumbnailLink]; if (url) {nsrttffrem = [auto_imageFrameForInteriorFrame: frame]; NSImage * image = [[NSImage alloc] initWithContentsOfURL: url ]; [Image setscales when resized: Yes]; [Image set size: NSMakeSize (IMAGE_HEIGHT, IMAGE_WIDTH)]; [NSGraphicsC Ontext saveGraphicsState]; ImageFrame = NSInsetRect (picture frame, 1, 1); NSBZIREPT * clippath = [NSBZearpathBeaserPathwithSteath: Image Frame Corner: 5.0]; [clippath set wading rule: NSEOOWDingArail]; [clippath adclip]; [NSGraphicsContext restorationGraphicsState]; [ Image drawInRect: imageFrame fromRect: NSMakeRect (0, 0, 0, 0) Operation: NSCompositeSourceIn fraction: 1.0]; [image release];}} ...

?

Draws your image Other clips need to be kept in the set, and after that the context has to be restored. Besides, I do not think you want to use "these" composites, but rather on "over" if you just want to make your image normal Keeping in mind the destination without ambiguity. Try to do something like this: 

  [Save NSFX contentGraphicsState]; NSBezierPath * Path = [NSBJairpath BezierPathwithWithRecordCourt: Image Frame x radius 5 yRadius: 5]; [Path adclip]; [Image drawInRect: imageFrame fromRect: NSZeroRect Operations: NSCompositeSourceOver fraction: 1.0]; [NSGraphicsContext ReplaceGraphicsState];

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
