问题 I am trying to make a movie, whilst creating frames through a loop. It is saving, but only the first frame (which it plays as a movie - short movie!) I've tried various things and cannot figure out what I am doing wrong. Thanks def synthesiseFrame(folder): folder =r"D:\FOLDER" m=0.5 for x in range(1,121): pic=makeEmptyPicture(960,540) for x in range (0,960): for y in range (0,540): r=#some code g=#some code b=#some code color =makeColor (r,g,b) px= getPixel (pic, x, y) setColor(px, color)

问题 I wrote a WebSocket frame decoder in Java: private byte[] decodeFrame(byte[] _rawIn) { int maskIndex = 2; byte[] maskBytes = new byte[4]; if ((_rawIn[1] & (byte) 127) == 126) { maskIndex = 4; } else if ((_rawIn[1] & (byte) 127) == 127) { maskIndex = 10; } System.arraycopy(_rawIn, maskIndex, maskBytes, 0, 4); byte[] message = new byte[_rawIn.length - maskIndex - 4]; for (int i = maskIndex + 4; i < _rawIn.length; i++) { message[i - maskIndex - 4] = (byte) (_rawIn[i] ^ maskBytes[(i - maskIndex -

问题 In my application, I am receiving many Skipped frames message from Choreographer. So, I started checking one by one, and I was very much surprised to see 76 Skipped frames when I just click on the default menu button on my MainActivity page. To find out the problem, I commented out almost all methods from my MainActivity java, and still I am getting 77 Skipped frames! There is not Skipped frames message during loading of MainActivity page, it just pop up whenever I click on menu button on top

why might layoutSubviews NOT automatically be called on a view when its frame is set?

依然范特西╮ 提交于 2019-12-01 06:42:15
问题 I have a view. It is part of a large and complex project. When the frame of my view is set, layoutSubviews is not automatically called. Playing around with this, I tried putting the following method into my view: -(void) setFrame: (CGRect) frame { NSLog (@"setting frame"); [super setFrame: frame]; [self setNeedsLayout]; } At this point, layout was redone when the frame was set, as expected. And if I commented out the setNeedsLayout line, layout was not done. Furthermore, when I click on "step

iOS Frame by Frame video playback forward/backward

淺唱寂寞╮ 提交于 2019-12-01 06:20:35
问题 I'd like to show a video on an iOS device in slow motion. My view contains a video (~2 seconds long) and a slider. The user can move the slider and step (forwards and backwards) through the movie frame by frame. MPMoviePlayerController lacks the ability to step frame by frame. I read about MVAssetReader , but I have no concrete idea how to use this. I don't have a fixed framerate, so it should take this information out of the metadata of the video. I really need to show every frame. Can

Android Camera PreviewCallback not called in 4.1

徘徊边缘 提交于 2019-12-01 05:23:34
I have an application to get camera preview frames with a surface. It was working on Android 4.0.4 but it does not work with Jelly Bean, 4.1.2 on the same device after the update. Simply, the callback is never called back. Here is the code: Snipped a little bit: public class Panel extends Activity { Camera myCamera; int cameraId = -1; MyCameraSurfaceView myCameraSurfaceView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_panel); myCamera = getCameraInstance(); myCamera.setPreviewCallback(new Camera

How to make the frame of a button custom shape in Swift 2

倾然丶 夕夏残阳落幕 提交于 2019-11-30 23:53:47
I want the button to be reactive to tap only in the custom polygonal shape that I create and not in the CGRect frame. button.frame only supports CGRect. Here is an example of a button that only responds to touches within a certain area. class MyButton: UIButton { var path: UIBezierPath! override func awakeFromNib() { backgroundColor = UIColor.greenColor() addTarget(self, action: #selector(touchDown), forControlEvents: .TouchDown) } override func drawRect(rect: CGRect) { path = UIBezierPath() path.moveToPoint(CGPointMake(150, 10)) path.addLineToPoint(CGPointMake(200, 10)) path.addLineToPoint
