frame

问题 Is it possible to get frames while recording a video and writing current time on those images at the same? I've been looking for this but I couldn't find anything. I want to write time on each frame and/or save those frames with that timestamp. I couldn't get the time information from a video for each frame, so I came up with this solution. I am open for any ideas. Thanks in advance. 回答1: Yes it is possible. The cap.get(0) flag, (where cap is a cv2.VideoCapture object), gives you the

问题 My code needs some help from professional xcoders :-) I have a draggable uitextview called "headline" that is a subview in "mainstage". I also added a pinch gesture to change the fontsize inside the uitextview. Everything works fine but the last essential feature that I really need is the rotation of the uitextview. So I added a uislider for rotation and volia! it also works. But after this transformation the uitextview goes crazy* when it becomes a new size via the pinch gesture. (*The

问题 I have set a UIView in my storyboard and make it an outlet. @property (nonatomic, weak) IBOutlet UIView *testView; In the - (void)viewDidLoad method, I want to change its frame like this CGRect frame = self.testView.frame; frame.size.height = 2; self.testView.frame = frame; But it does not work. Anybody can tell me why? 回答1: You might enabled the autolayout in your project , if so the setFrame straightly won't work . Check here for more info Solution : Disable the autolayout, if you don't

问题 When I start up my game it stays around 95-101 rapidly changing, in between all of those numbers.. but when I open up the stats bar I'm getting upper 200's low 300's so wondering why that is still new to c# so be easy on me lol. heres the code thanks in advance as always ^_^. float deltaTime = 0.0f; void Update() { deltaTime += (Time.deltaTime - deltaTime) * 0.1f; } void OnGUI() { int w = Screen.width, h = Screen.height; GUIStyle style = new GUIStyle (); Rect rect = new Rect (0, 0, w, h * 2 /

问题 I applied CATransform3D to a view. How can I find its approximate new frame after it? I mean I applied a complex transform: rotation, translation, scale and perspective. And I need to find something like approximate minimal rect. I need it because this view is added to UIScrollView (to know the contentSize I need and of course to implement "scrollToItem:") 回答1: If you want to get the CGRect that completely contains this transformed view, you can use convertRect:toView: . For example: CGRect

问题 As far as I understand it, the stack pointer points to the "free" memory on the stack, and "pushing" data on the stack writes to the location pointed by the stack pointer and increments/decrements it. But isn't it possible to use offsets from the frame pointer to achieve the same thing, thus saving a register. The overhead from adding offsets to the frame pointer is pretty much the same as the overhead of incrementing and decrementing the stack pointer. The only advantage I see is accessing

问题 i have two frame in my whole website. a frame with navigation bar and another frame with main content. when i click on a link, I want the other frame (content frame) to fade in and out, how would I accomplish this?
