This project is a browser-based rendering engine that captures visual snapshots of web page elements. It functions as a document object model to canvas renderer, programmatically reconstructing the visual appearance of web content by interpreting CSS box models and document structures directly within the client environment.

The tool distinguishes itself by performing all image generation locally, eliminating the need for server-side processing or external rendering services. By simulating browser layout logic and mapping geometric shapes and text properties to pixel-based drawing commands, it enables the conversion of complex web layouts into downloadable image files.

The engine supports a range of capabilities including the creation of persistent visual archives, automated reporting, and the exporting of dynamic interface components. It manages the retrieval of external assets such as images and fonts through a proxy mechanism to maintain compatibility with browser security constraints.
