Asp.net: <asp:TextBox runat="server" ID="txtCelular" CssClass="w240 placeholder"></asp:TextBox> javascript: <script src="\scripts\jquery-1.7.2.js" type="text/javascript"></script> <script type="text/javascript"> $("#txtCelular").mask("(999) 9999-9999?9"); $("#txtCelular").on("blur", function () { var last = $(this).val().substr($(this).val().indexOf("-") + 1); if (last

问题 I try to draw a triangle shape over the text, and to have the shape be painted where it intersects the text. When I try to apply the mask, text just disappears. Here's the code: import UIKit class ViewController: UIViewController { @IBOutlet weak var messageLabel: UILabel! let maskLayer = CAShapeLayer() override func viewDidLoad() { super.viewDidLoad() drawMask() messageLabel.layer.mask = maskLayer } func drawMask(){ let path = UIBezierPath() let xMsgLbl = messageLabel.center.x-80 let yMsgLbl

问题 I have a JavaScript parser plug-in in Visual Studios 2012 and it is throwing an error at line 30 of this code, which is the closing curly brace for the $.mask piece from Mr. Bush: /* Masked Input plugin for jQuery Copyright (c) 2007-2013 Josh Bush (digitalbush.com) Licensed under the MIT license (http://digitalbush.com/projects/masked-input-plugin/#license) Version: 1.3.1 */ (function($) { function getPasteEvent() { var el = document.createElement('input'), name = 'onpaste'; el.setAttribute

问题 I have the following image: On a UIImageView of the exact same frame size, I want to show everything but the red fill. let mask = CALayer() mask.contents = clippingImage.CGImage self.myImageView.layer.mask = mask I thought the black color would show through when applied as a mask, but when I set the mask the whole view is cleared. What's happening here? 回答1: When creating masks from images, you use the Alpha channel, rather than any RGB channel. Even if your mask is black, you need to set its

问题 I have a 2D selection or mask array, with shape (375, 297) that has in each cell a value that corresponds to an index integer number, ranging from 0 to 23. I’d like to use this 2D array to select in a 3D array (with shape (24, 375, 297)) the cells from the first dimension (the one with length 24) so to output a 2D array with shape (375,297). I've been trying with fancy indexing and xarray package without success. How to do that using python 3.6? Small example: 2D selection array or mask (2,3)

问题 I'm running python program with openCV on Raspberry-Pi . I got super wierd OpenCV Error . It looks it must not be happend, but is happened. In short, mask s croped by cv2.inRange() is different with same image . Simple structure of my code: process images into mask and calculate kind of accuracy. If mask is not gather in (1.), which means mask of image is all black(empty) np.array , it skip an iteration by exception: Value Error command.(Because min(empty np.array) in code araise Value Error

问题 I want to create a mask with iterating over the tensor. I have this code: import tensorflow as tf out = tf.Variable(tf.zeros_like(alp, dtype=tf.int32)) rows_tf = tf.constant ( [[1, 2, 5], [1, 2, 5], [1, 2, 5], [1, 4, 6], [1, 4, 6], [2, 3, 6], [2, 3, 6], [2, 4, 7]]) columns_tf = tf.constant( [[1], [2], [3], [2], [3], [2], [3], [2]]) I want to iterate through rows_tf and accordingly columns_tf to create a mask over the out . for example, it will mask the index at [1,1] [2,1] and [5,1] in the

问题 I want to create a mask of a RGB image based on a pixel value but the following code segment throws error ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all() I can provide the image if it is at all required. Here is the code segment image = cv2.imread("abcd.png") for k in range(image.shape[0]): for l in range(image.shape[1]): if(image[k][l]==[255,255,255]): mask[k][l]=255 else: mask[k][l]=0 I wonder what is the problem in the code? 回答1:

问题 I have got customer.mydomain1.com and want to mask it to customer.mydomain2.com so that customer.mydomain1.com shows content of customer.mydomain2.com and url stays the same as of customer.mydomain1.com I am using the code below used in my .htaccess, which gives me ERROR 400 RewriteEngine On RewriteCond %{HTTP_HOST} ^customer.mydomain1.com RewriteRule ^(.*) http://customer.mydomain2.com/$1 [P] 回答1: I would just use a ServerAlias this works for any domain that have an A-Record or a CNAME

问题 I am trying to understand what's the size difference between a numpy masked array and a normal array with nans. import numpy as np g = np.random.random((5000,5000)) indx = np.random.randint(0,4999,(500,2)) mask = np.full((5000,5000),False,dtype=bool) mask[indx] = True g_mask = np.ma.array(g,mask=mask) I used the following answer to compute the size of the object: import sys from types import ModuleType, FunctionType from gc import get_referents ​ # Custom objects know their class. # Function
