objective c - Initialize an image from a given path in swift? -

-

I object> This code

selectedImage = [[NSImage alloc] initWithContentsOfFile: [_the path path]]; If (selectedImage.size.width & lt; selectedImage.size.height) {imageProportion = selectedImage.size.height /selectedImage.size.width; [Selected image set size: nsmcases (690.0, 690.0 * imagepropation)]; } Other {imageProportion = selectedImage.size.width /selectedImage.size.height; [Selected image set size: nsmcases (690.0 * imageproportion, 690.0)]; } [_imageEditorWindow orderFront: nil]; [_imageViewEditor setFrameSize: NSMakeSize (selected image size.width, selectedImage.size.height)]; InitialImageSizeH = Selected Image.size.height; InitialImageSizeW = Selected Image.size.width; [_imageViewEditor setImage: selectedImage]; [_imageViewEditor setFrameOrigin: NSMakePoint (45, 35)];

If I write this code in Swift using the playground, but I get an error: 

  var selectedImage = NSImage (byReferencingURL: NSURL (string: "/ users / admin / desktop / 10658771_575156615924178_8253607361793017933_o.jpg"))

and fail if I use this code: 

  var selectedImage = NSImage (byReferencingFile: "/Users/admin/Desktop/10658771_575156615924178_8253607361793017933_o.jpg")

So, what is wrong? Do these errors say that my file is not an image?

Thank you, and sorry for my English!

It is looking for a TIFF image representing NSBitmapImageRep to NSImage . I recently got this issue and found that it is making a NSBitmapImageRep and approved it for the NSImage presentation.

assuming that the image is a NSImage example 

  let's go = image =. CGImageForProposedRect (zero, reference: zero, signal: zero)! Give rep = NSBitmapImageRep (CGImage: cg) image.addRepresentation (self.bitmapRep)

Give it a try and see if it works better Now your methods get TIFF representation from the image Should be able to

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
