问题 Background I wanted (here) to see how to create an alternative to AdaptiveIconDrawable , but change its background drawable to be shaped in to a given Path . The problem Well, what I did worked for Bitmap, but I wanted to know if it's possible to convert a given Drawable directly to a Bitmap and even a Drawable that is shaped to the given Path , without creating extra Bitmap instances. What I've tried This is the current code : fun resizePath(path: Path, width: Float, height: Float): Path {

问题 How can I create a mask via react-text-mask that can have only 14 digits? Something like this: export default function NumberMask(props) { const { inputRef, ...other } = props; return ( <MaskedInput {...other} ref={(ref) => { inputRef(ref ? ref.inputElement : null); }} mask={[?? , '______________']} placeholderChar={'\u2000'} size={14} showMask /> ); 回答1: As a regular expression /\d{14}/g regarding react-text-mask I guess mask={[/\d{14}/]} 来源： https://stackoverflow.com/questions/64976153

问题 I have this code to show an image inside text in flutter but when I'm using ImageShader. I'm getting this error The method 'asset' isn't defined for the type 'Image'. Try correcting the name to the name of an existing method, or defining a method named 'asset' I have also referred to this Repo. This repo link was given in previously asked question on StackOverflow about ImageShader. I know "dart:ui" doesn't contain any asset method. So I used Image.asset but when I used this method I got this

问题 I'm using SceneKit and ARKit 1.5, once a surface has been mapped I apply a material to it. I would like to only show what's under the camera in a certain radius with an alpha effect. I want to keep the material static meaning that it does not move when the camera moves, only the radius shape will move. What kind of technique could I use for this ? ArCore by Google does this perfectly. Actual rendering: Desired Rendering: ARCore example: (click to see GIF) Thank you! 回答1: I would use a shader

问题 I am using Konva.js framework and trying to apply an image mask over an other one. The code is fully copied from this post. In this jsfiddle example there is small modifications to add a background (Rect). The problem is that the background is not properly drawn. To see it in action in the code there is a line to comment/uncomment (to see the problem in action). Is someone have any idea to achieve this ? Best let stage = new Konva.Stage({ container: 'container', width: window.innerWidth,

问题 I have made a putt-putt game and now I want to add a slanted wall type. Because of this, I need to use masks for the collision (until now I have just used rects). I have spent hours learning about masks and trying to figure out why my code won't work. There are no errors, the collision just isn't detected. I have simplified my code down to something much smaller just as a way for me to test it efficiently. From everything I've seen this seems like it should work, but it doesnt. Here it is:
