CANVAS · COMPOSITION

Image composition

Place project assets inside a retained scene, then layer portable geometry, opacity, rotation, and typography above or below them.

PROJECT ASSET

/assets/logo.svg

The example remains local to the project and does not depend on a third-party image service.

ADVANCED EXAMPLE

Create a layered artboard

The scene starts with a theme-aware background, adds translucent color, rotates a panel, fits a local asset, and finishes with centered text.

SOURCE

Fit assets inside logical coordinates

An image command accepts a project asset path or HTTPS URL. Its own fit controls the source inside the command rectangle; Canvas fit controls the complete logical scene inside the component.

IMAGE RENDERING

Keep the portable boundary clear

Image fit

contain shows the complete asset, cover fills and crops, and stretch maps it to the command bounds.

Pixel sampling

Set pixelated:true on Canvas when image commands should render without smoothing.

Current limits

Arbitrary pixel filters, shaders, and video-frame processing are not supported.
