flood-fill's Introduction

flood-fill

A TypeScript implementation of flood-fill that supports setting custom alpha values for the replacement color.

Click here to try it out!

Usage

  1. Open the web page.

  2. Upload an image.

  3. Choose your replacement color.

  4. Choose your tolerance.

    • Tolerance is defined as the Euclidean distance threshold under which the algorithm will continue filling.
    • Tolerance defaults to 0, meaning the algorithm will only continue filling the adjacent pixels that exactly match the target color.

  5. Click to flood-fill.

Motivation

If you Google "online fill bucket", you can find a plethora of existing flood-fill tools. However, I have yet to see one that allows you to configure the alpha value of the replacement color. This is problematic, as my primary use case for flood-fill is to remove opaque backgrounds.
