问题 Check out my html5 based clipping constraint on http://shedlimited.debrucellc.com/test3/canvaskinclip.html (messing with jsfiddle on http://jsfiddle.net/aqaP7/4/) So, in html5 I can easily draw a shaped boundary like the following: context.beginPath(); context.moveTo(5, 5); context.lineTo(34, 202); context.lineTo(2, 405); context.lineTo(212, 385); context.lineTo(425, 405); context.lineTo(400, 202); context.lineTo(415, 10); context.lineTo(212, 25); context.clip(); In kinetic.js though, all I

问题 I am able to change the color of an image of a UIButton from black to white with the following code: extension UIImage { func maskWith(color: UIColor) -> UIImage { UIGraphicsBeginImageContextWithOptions(size, false, scale) let context = UIGraphicsGetCurrentContext()! context.translateBy(x: 0, y: size.height) context.scaleBy(x: 1.0, y: -1.0) context.setBlendMode(.normal) let rect = CGRect(x: 0, y: 0, width: size.width, height: size.height) context.clip(to: rect, mask: cgImage!) color.setFill()

问题 here is my code, no matters what I do I keep on getting the error and followed all the index related solutions, can anyone help me? site = pd.read_csv('../data/survey_site.csv') sampled = site.sample(n=1) site = site.reset_index(drop=True) sampled = sampled.reset_index(drop=True) mask = site.mask(site['name'] == sampled['name']) 回答1: The issue is the comparison between site['name'] and sample['name'] is between two pd.Series . You can bypass that by making one of them a scalar. However, I

问题 I have a question about how to apply multiple masks to a UIView that already has a mask. The situation: I have a view with an active mask that creates a hole in its top left corner, this is a template UIView that is reused everywhere in the project. Later in the project I would like to be able to create a second hole but this time in the bottom right corner, this without the need to create a completely new UIView. The problem: When I apply the bottom mask, it of course replaces the first one

问题 I have a container MovieClip that serves as a content area that I need to mask off. When I create a mask inside this container using a Shape I can't seem to interact with the contents of other containers I create here, like buttons etc. This is what I'm doing in code (I've left out all the import's etc.): class MyContainer extends MovieClip { protected var masker : Shape = null; protected var panel : MyPanel = null; public function MyContainer() { this.masker = new Shape(); this.masker

问题 I want to use phone mask on my input value. I'm bad with Angular 2 experience.

问题 I have two masks that I would like to merge together, overwriting mask1 with mask2 unless mask2 has a zero. The masks are not binary, they are some value that is user defined in the region of interest and 0 elsewhere. For example if: mask1=[0 5 5;0 5 5]; mask2=[4 4 0;4 4 0]; then I would want an output of [4 4 5;4 4 5] . And if I then had another mask, mask3=[0 6 0;0 6 0]; then I would want an output of [4 6 5;4 6 5] There has got to be an easy way of doing this without going through and

问题 User, I want to crop that Triangle on the image and show it in another window with opencv c++. I know all three Coordinates. Can anyone help me? I did not find any answer on the Internet about "triangle cropping". Thanks! EDIT: The Problem here is that i cannot use ROI for cropping the Triangle. I have to copy just the triangle without any background or something around. Is it possible to create my own ROI by knowing the Coordinates of the triangle [p1(302,179), p2(329,178), p3(315,205)]? 回答1

问题 I need to format a number with a specifc mask: 9.9.9.9.99.999 , depending on the length of number string. For example: - 123456789 => 1.2.3.4.56.789 - 123456 => 1.2.3.4.56 - 1234 => 1.2.3.4 - 123 => 1.2.3 - 12 => 1.2 It will not occur a number string with 7 or 8 digits in the input. How could that be implemented with regex, preferably in python? Thanks in advance. 回答1: You can use this pattern: (?:(?<=^\d)|(?<=^\d{2})|(?<=^\d{3})|(?<=^\d{4})|(?<=^\d{6}))(?=\d) with . as replacement. example:
