mask

问题 Q: I wanna to mask my textbox , so if the user enter the number one for example it formatted as 0000001 how to do this ,any number in 7 digits. 回答1: I think you are going to need something like this padding function. You could listen for a keypress then as soon as it is fired, use getElementById() to get your elements content, you could then run the padding function on it and put the padded value back in. 回答2: I think you need to use MaskedEditExtender in Ajax. Set its properties such as

问题 this is the result that I have from my code : enter image description here I've made this mask on my face using contour , as I show bellow in the code . the final result of the project is to delete the face and show the background that I am not defined it yet . my question is : is there any way to make a mask with this counter so i could use something like this cv2.imshow('My Image',cmb(foreground,background,mask)) to just show the foreground under the mask on the background ? ( the problem

问题 I'm finishing up some CSE homework and I have a quick question about declaring integers of larger bit sizes. My task is to implement a function that returns 1 if any odd bit of x is 1 (assuming size of x is 32 bits) and returns 0 otherwise. Am I allowed to declare an integer with the bit value: 10101010101010101010101010101010 If so, are there any problems that could arise from this? If not, why not?? What alternatives do I have? My function: int any_odd_one(unsigned x) { int mask =

问题 I want to create a mask on camera surface view. see image below. mask is resizable. image will be clicked only by unblurred area. can anybody give idea how to create suh mask? thanks in advance. 回答1: You can't draw on the Surface of the SurfaceView that is receiving the camera preview. You have two basic options: draw on the View part of the SurfaceView, treating it as a custom view, or create a second SurfaceView and layer it on top of the camera surface. For the latter, you would use

问题 I just came across a function I dont understand, and I was wondering if you could explain it to me. unsigned long long x(unsigned long long value, int begin, int end) { unsigned long long mask = (1 << (end - begin)) - 1; return (value >> begin) & mask; } Thanks uksz 回答1: The above function serves as a mask to extract a range of bits from a number. It can be broken down into four steps. First step: mask = 1UL << (end - begin) The << logically shifts 1 to the left by end - begin bits. Since the

问题 Is there any way to detect if an object with a certain amount of vertices hits a plane? If so, I want to draw it in binary (black/white) onto the plane or create a texture with it. And I also don't care about if this can only be created with raycasts or some tricky physics operations / shaders / etc.. I'm just wondering what mathematical algorithm could create this. Here is an example of what I'm trying to achieve: Cheers, Michael 回答1: Most games will achieve this with specialized shaders:

问题 I don't understand how swiffy succefully antialias clipping mask when it exports a flash animation that contains mask. Here is my exemple : Full canvas, with mask. Super dirty in Chrome : http://goo.gl/n8yB5h And a swiffy export where there is a picture that move inside a mask. Super clean on Chrome : http://www.creaktif.com/lab/test4.html I tried a lot of things, including draw a 200% canvas then scale it down, adding more points when I draw my mask, but no way to get a clean mask in my

问题 I have numpy array : np.random.seed(100) mask = np.random.choice([True, False], size=(10,3)) print (mask) [[ True True False] [False False False] [ True True True] <- problem - all values True [ True True False] [ True True True] <- problem - all values True [ True False True] [ True False True] [False True True] [ True False False] [False True True]] Need in each row no all values True - so here can be only 0 , 1 or 2 True because 3 'columns' . Ugly solution is: mask[:, -1] = False print
