Get started with Rasterex based on your role or immediate need.

Your application orchestrates the user experience and drives the canvas lifecycle.

• Embed and size the iframe within your responsive layout.
• Orchestrate canvas sessions by providing file contexts and metadata.
• Handle canvas events (markups, exports) to keep your local state in sync.
• Trigger tool and navigation commands based on user intent.

The Canvas handles the complex logic of rendering and document state.

It emits real-time updates so the Host can reflect file state and tool activity.

• Render multi-format documents and maintain active tool state.
• Emit progress, file, and tool-action events to the host.
• Process incoming commands like tool selection, tab switching, and exports.

The iframe boundary keeps the rendering engine isolated from your application logic.

Origin validation ensures that only trusted messages from your host origin are processed by the Canvas.
