// width (number)
// height (number)
// depth (number of palette entries)
// [backgroundColor] (optional background color, when omitted 'transparent' is used)
const image = new PNGImage(100, 100, 8);
 
// Add colors to the palette (uses tinycolor for converting the color)
const redColor = image.createColor('#FF0000');
const blueColor = image.createColor('blue');
const greenColor = image.createColor('rgba(0, 255, 0, 1)');
 
// Do some pixel drawing
image.setPixel(50, 50, redColor);
const color = image.getPixel(50, 50);
...
 
// Convert image to base-64
const base64 = image.getBase64();
 
// Or get the data-url which can be passed directly to an <img src>
