Claudoodle Research

Introduction

Claudoodle is a completely local WebComponents application that allows you to convert SVG files to PNG wallpapers for your desktop. It runs entirely in your browser with no server-side processing or data transfer, ensuring your designs stay private and secure.

With Claudoodle, you can:

• Drop in any SVG file from your computer
• Select from common desktop wallpaper resolutions
• Use your device's actual screen resolution for perfect-fit wallpapers
• Create custom-sized wallpapers as needed
• Convert your SVG to a high-quality PNG
• Download the result directly to your device

How to Use Claudoodle

Step-by-Step Instructions

1. Select an SVG File: Either drag and drop your SVG file onto the upload area or click the "Choose File" button to select one from your computer.
2. Choose a Wallpaper Size: Select one of the common desktop resolutions or enter custom dimensions.
3. Convert to PNG: Click the "Convert to Wallpaper" button to transform your SVG into a PNG image at the selected resolution.
4. Preview and Download: Preview the generated wallpaper and click "Download Wallpaper" to save it to your device.

Technology Stack

Claudoodle is built using modern web standards and technologies that enable it to run entirely in the browser:

Core Technologies

• Web Components: Custom elements for encapsulated, reusable UI components
• Shadow DOM: Encapsulation of component styles and structure
• HTML Templates: Declarative component templates
• ES Modules: Modern JavaScript module system for clean code organization

Key APIs

• File API: For handling file uploads and parsing
• Canvas API: For rendering SVGs and creating PNG exports
• Drag and Drop API: For intuitive file uploading
• Blob API: For handling binary data and downloads
• Screen API: For detecting device screen resolution

No Dependencies

Claudoodle is built with zero external dependencies or frameworks, using only native browser capabilities. This results in:

• Smaller file size and faster loading
• No security concerns from third-party code
• Long-term stability without dependency rot
• Better performance through direct browser APIs

How It Works

SVG to PNG Conversion Process

The core functionality of Claudoodle revolves around converting scalable vector graphics (SVG) to raster PNG images at specific dimensions. Here's how it works under the hood:

1. SVG Loading: When you upload an SVG file, it's read using the FileReader API and parsed into an XML document.
2. Canvas Creation: A hidden HTML Canvas element is created with the dimensions matching your selected wallpaper size.
3. Rendering: The SVG is rendered onto the canvas using the drawImage method of the Canvas 2D context. This converts the vector data to a bitmap representation.
4. Data Extraction: The PNG data is extracted from the canvas using toDataURL() or toBlob() methods.
5. Download Preparation: The PNG data is associated with a download link, allowing you to save the wallpaper to your device.

Web Components Implementation

Claudoodle uses custom elements to create a modular application structure:

<svg-wallpaper-converter>
  <file-drop-area></file-drop-area>
  <size-selector></size-selector>
  <wallpaper-preview></wallpaper-preview>
</svg-wallpaper-converter>

Each component handles its specific responsibilities:

• svg-wallpaper-converter: The main component that orchestrates the conversion process
• file-drop-area: Handles file uploads and drag-and-drop functionality
• size-selector: Manages resolution selection and custom sizing
• wallpaper-preview: Displays the converted image and provides download capabilities

This component-based architecture makes the code more maintainable and allows for easy future expansion.
