@image-tracer-ts/nodejs

Trace images into SVG in nodejs.

Adds nodejs-specific convenience methods to @image-tracer-ts/core to load data from different image types (PNG, JPEG, etc.) and locations (mainly filenames), as well as command line support.

Provides ESM and CJS packages.

A similar package is available for browser usage in @image-tracer-ts/browser.

Basic Usage

import { ImageTracerNodejs } from '@image-tracer-ts/nodejs' 
const svgString = ImageTracerNodejs.fromFileName(
  fileName: string,
  options: Partial<ImageTracerNodejsOptions> | null = null,
  drawer: ImageDrawer<string> | null = null
): Promise<void>

CLI

To trace images from the command line, run the .cjs module with a path to an image along with the desired options (prefixed with --):

$ node ./packages/nodejs/dist/image-tracer-nodejs.cjs ./image.png --out image.svg --fillStyle stroke

---

Options

For tracer options see @image-tracer-ts/core.

When passed as command line parameter, options have to be prefixed with -- (i.e. --blurRadius 5).

Package specific options:

Option	Type	Default	Description
output	png | svg | `(png	svg)[]`	svg
out	string	input file name	Output filename (file type extension will be added if necessary)
preset	Preset name from core package	null	Use a named preset
