README for the Svelte Canvas Text Renderer

Introduction

This Svelte application allows users to dynamically generate and download images with custom text. The core functionality revolves around rendering text onto a canvas, which then gets converted into an image. Users can adjust the "BRATINESS" (image quality), the scale of the text, and observe the background color dynamically adapting to the generated image.

Features

Custom Text Input: Users can input any text they wish to render onto the canvas.
Adjustable Image Quality: Through a slider labeled "BRATINESS", users can adjust the quality of the generated image, which affects the file size and clarity.
Scalable Text Size: A "SCALE" slider allows users to adjust the size of the text rendered on the canvas.
Dynamic Background Color: The application samples the generated image's dominant color and applies it as the background color of the page.
Image Download: Users can download the generated image with their custom text as a JPEG file.

How It Works

Rendering the Image:
- A canvas element is created off-screen, where the text is rendered with the specified scale and quality.
- The background color of the canvas (computedBg) is dynamically set, and the text is rendered in the center.
- An image data URL is generated from this canvas, which is then used to load an image element on the page.
Sampling Background Color:
- Once the image is loaded, its color is sampled to dynamically change the page's background color to match the generated image's dominant color.
User Interactions:
- Users can interact with the application through inputs: changing the text, adjusting image quality, and scaling the text size.
- Adjustments immediately trigger the re-rendering of the canvas and the subsequent processes.

Development

This application is built with Svelte, a modern JavaScript compiler that enables reactive and efficient web applications.

Requirements

Node.js
A package manager like npm or Yarn

Getting Started

To get started with the development:

Clone the repository.
Install dependencies:
```
npm install
```
Start the development server:
```
npm run dev
```
Open your browser and navigate to http://localhost:5000.

Structure

The main logic is encapsulated within a single Svelte component, which manages state, user inputs, and rendering logic.
The application's styles are defined in a <style> tag within the same component, ensuring scoped and maintainable CSS.
