sjotorp_image
This is a node module for generating random images.
- Works platform independent
- Needs no building thanks to jpeg-js
- Generates random colored images
I needed this for creating dummy datasets including images in combination with faker.js and / or choice.js
Uses the jpeg-js library: https://github.com/eugeneware/jpeg-js
Installation
npm install sjotorp_image
Example Usage
var fs = require('fs');
var imgGen = require('sjotorp_image');
// Generate one image
imgGen.generateImage(800, 600, undefined, function(err, image) {
fs.writeFileSync('dummy.jpg', image.data);
});
// Generate multiple images
// Will generate same color on the images every time we run since we use the
// fileName as a seed
for(var i=1;i<=10;i++){
var fileName = 'dummy-' + i + '.jpg';
var color = imgGen.generateColor(fileName);
imgGen.generateImage(800, 600, color, function(err, image) {
console.log("Generating image #" +i);
fs.writeFileSync(fileName, image.data);
});
}
