swift - Animated resizing of a NSView does not effect layer. Bug or totally correct? -

-

i have 2 nsview subclasses:

  • drawrectview draws background color using drawrect method
  • layerbackedview draws background color using layer backing

the following code snippet resizing animation via click actions on views:

@ibaction func clickdrawrectview(sender: nsclickgesturerecognizer) {     let height = drawrectview.frame.height * 1.2     let width  = drawrectview.frame.width * 1.2     nsanimationcontext.runanimationgroup({ (context) in         context.duration = 1.0         self.drawrectview.animator().frame = nsmakerect(self.drawrectview.frame.origin.x, self.drawrectview.frame.origin.y, width, height)     }, completionhandler: nil) }  @ibaction func clicklayerbackedview(sender: nsclickgesturerecognizer) {     let height = layerbackedview.frame.height * 1.2     let width  = layerbackedview.frame.width * 1.2     nsanimationcontext.runanimationgroup({ (context) in         context.duration = 1.0         self.layerbackedview.animator().frame = nsmakerect(self.layerbackedview.frame.origin.x, self.layerbackedview.frame.origin.y, width, height)     }, completionhandler: nil) }

the drawrectview animates expected, layerbackedview not. jumps next rect animation.

so how bring same animation layer-backed view?

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
