Usage

import { createStore } from 'matrix-display-store';
import { LEDMatrix } from 'led-matrix';

const store = createStore(32, 16);
const matrix = new LEDMatrix(canvasElement, {
  x: 32,
  y: 16,
  // other options...
});
matrix.setData(store.matrix);
matrix.render();

Options

{
  x: number;
  y: number;
  pixelWidth: number;
  pixelHeight: number;
  margin: number;
  glow: boolean;
  animated: boolean;
}

Store Methods

• store.write(x, y, text, font, size, color)
• store.fill(x, y, r, g, b, a)
• store.drawPixel(x, y, r, color)
• store.drawLine(x1, y1, x2, y2, color)
• store.drawFastVLine(x, y, h, color)
• store.drawFastHLine(x, y, w, color)
• store.drawRect(x, y, w, h, color)
• store.drawRoundRect(x, y, w, h, radius, color)
• store.drawTriangle(x1, y1, x2, y2, x3, y3, color)
• store.drawCircle(x1, y1, radius, color)
• store.fillScreen(color | null)
• store.fillRect(x, y, w, h, color)
• store.fillRoundRect(x, y, w, h, radius, color)
• store.fillTriangle(x1, y1, x2, y2, x3, y3, color)
• store.fillCirlce(x, y, radius, color)
• store.drawBitmap(x, y, bitmap, w, h, color)

Color Tools

The Store accepts colors in IRGBA type:

interface IRGBA {
  r: number;
  g: number;
  b: number;
  a: number;
}

To make working with this object easier, this module exports some color conversion tools:

import { Color } from 'matrix-display-store';

Color.hex('#FF0000');
Color.hex(0xFF0000);
Color.rgba(255, 255, 255, 0.5);
