Image & Canvas
canvasLoadImage
$canvasLoadImage[]
Loads an image from a URL, data URL, or base64 string onto the canvas
Syntax
$canvasLoadImage[url;x?;y?;width?;height?;container?]
$canvasLoadImage is dual-purpose: when no canvas exists, it creates one from the loaded image. When a canvas already exists, it composites the image on top. HTTP images are cached in a 50 MB LRU cache that persists for the lifetime of the current deferred block. If the URL fails to load within 15 seconds, the operation silently fails and the canvas remains unchanged.
