@image-tracer-ts/nodejs

Trace images into SVG in nodejs.

!alt Bitmap to Svg

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 | null = null,
drawer: ImageDrawer | null = null
): Promise
`

$3

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 | Output file type |
| 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 |
