How to predict the QR scan result of the mobile camera? - vue.js

Thanks to the help of Ohgodwhy, I realized that it is possible to use QR code for a advertising, too.(question) Just scanning code shows the banner with options of Open Browser and Install App, it's really amazing.
I really want to realize this. I want to do it in my vue project. The problem is that I am not sure about the preview content of the link of the QR code. I am just embedding the link. The scanned result might show the link and hopefully the preview of the link.
But I am not sure how it would look like. Preview of the link are different on different platforms. Can you help me how to guess the content that will be shown by the mobile device as the banner when it successfully scanned the QR code?

Why does JS code render faster on website than react-native?

This is a bit of a general question, but perhaps someone can guide me in the right direction.
I'm using a JS library called Vexflow to render music notes. I uploaded some script to my website AND used the same code to build a React Native app.
When comparing both on the same device (Xiaomi A3), the code renders much faster on my website.
Any ideas why?
Cheers,

Can i get screenshot of desktop using vuejs

i am working on tracking app using vue.js. I am a new developer.i wanna know is it possible to track mouse click and capture screenshots even if person is on desktop or any where else on browser
This has nothing to do with VueJs specifically. However, you can use HTML5/Canvas/Javascript to take a screenshot, but that's still experimental.
Take a look at this answer: Using HTML5/Canvas/JavaScript to take in-browser screenshots
i have found the solution
i followed the steps here
https://www.webrtc-experiment.com/getScreenId/
these steps allowed me the screen sharing on my webpage and then i use html to canvas to get the image of the video tag

How can i add the Image Filter plugin in Xamarin.Form?

First of all I am new in Xamarin.Form. I am trying to get best from Google but some of functionality I am not able to get even searched a lot.

First of all I don't know whether it is possible in Xamarin.Form or not. Can anybody suggest me a link or idea to achieve it?
I attached a Screenshot so you can easily understand the problem.

There are no out of the box APIs in Xamarin.Forms for Image filters.
Each platforms handles the images differently, you will need to implement these filters per platform bases.
You can find the instructions for iOS here and here for Android, then you can use the DependencyServices to access them in Forms app

Using Titanium.Platform.takeScreenshot

I'm evaluating using Titanium for a project that makes videos from browser based animations. I was hoping for a way to take screenshots from within the app for each frame. The documentation of takeScreenshot seems a little slim so I was hoping to ask before I build a prototype.
Does take screenshot get the full document, or just the visible content?
Does the screenshot include window chrome?
Someone from titanium QA was able to answer the question. takeScreenshot actually takes a screenshot of the whole desktop.

Displaying image on Scroll View

I am developing an iPhone application where i want to display three image in each row on scroll view where i need to click action on each image like Photo album in iPhone. I am not getting any sample code.
Hoping for help

There's plenty of sample code out there, I found this after only basic googling. You want to search for "UIImageView Iphone". It's also worth mentioning that Apple's very own Developer Center is extremely well written, and will teach you everything you need to know about iPhone programming.
Generally it is frowned down upon to say to look more or read documentation, but you really haven't looked at all. Especially because of Apple's own resource that tells you how to do almost anything, especially something like this. It's not something you can pick up and bits and pieces of and expect to be successful with, it really should be learned starting from the beginning and moving forward. This is especially true if you've never programmed before or are unfamiliar with C/Objective-C.
Three20 has a photo browser that is open source and works similarly to the iPhone's photo browser with some nice code examples. The images come from an image source object that can relate them to images in your apps bundle or images on the web. Looks like its Google group is here. I think that to use images in your bundle you use a URL formed like: bundle://image-name.png and not the typical use of the main bundle to get a path to resource.
