Generate account images in Metamast: a step-by-step instructions

Metamask is a popular Ethereum letter pocket with which users can save, send and receive cryptocurrencies. One of his unique functions is the customizable account image for every user. While Metamask provides a standard image, the generation of a custom program tax can be achieved on the client page via JavaScript.

Why generate an account image program -controlled?

There are several reasons why developers may want to create an account image program -controlled:

• Adaptation : User may want to create their own unique profiles with different images.

• Automation : The automation of the generation and update account images can be useful for mass preparations or large-scale applications.

• Safety : Creating a custom image can help prevent phishing attacks by offering users control over your profile image.

Method 1: Use JavaScript to generate an image

Metamask provides a “Metamask” API with which developers can interact with the wallet and its functionality. To generate an account image -controlled, you must:

• Install the “ElectronLibrary

  ": If you use electrons, install the "Electron Webview" package to carry out your JavaScript code in a web view.

• Create a new script : Create a new file (e.g.Generate-image.js) and add the following code:

JavaScript

Const {ipcrenderer} = request (‘electron’);

Const Crypto = demands (‘Crypto’);

// Download the standard account -URL

Const url = ‘

// generate a new picture with web words

Function Generate realization () {

Const canvas = document.Createlement (‘canvas’);

canvas.width = 100;

Canvas.height = 100;

Const CTX = canvas.Getcontext (‘2D’);

// Draw the standard account image on the screen

ctx.drawimage (URL, 0, 0);

// Create a new image with the same dimensions and opacity as the original image

Const Newimage = New Image ();

newimage.src = url;

// Add an event listener to update the screen when the image is loaded

newimage.addeventlistener (‘load’, () => {

Const Width = canvas.width;

Const Hoh = canvas.height;

ctx.drawimage (newimage, 0, 0);

document.body.style.backgroundimage = url ($ {newimage.src});

});

Return [canvas];

}

// Send the generated image with IPC to Metamast

ipcrenderer.

`

• Conduct the script in a web worker : Create an HTML file (e.g. index.html) and add the following code:

`html

Body {

Width: 100%;

Height: 100VH;

Background color: #F0F0F0;

}

`

• Take out the HTML file : Open index.html in a web browser to carry out the script.
