Overview:

The Svelte-datocmsProgressive/responsive image component, called <Image />, is specifically designed to work seamlessly with DatoCMS’s responsiveImage GraphQL query. This component optimizes image loading for websites and is a port from the React version to Svelte.

Features:

• data: Requires a ResponsiveImage object that is obtained from a DatoCMS responsiveImage GraphQL query.
• fadeInDuration: Specifies the duration (in ms) of the fade-in transition effect during image loading. Default value is 500ms.
• intersectionThreshold: Defines the percentage of placeholder visibility at which the loading of the image should be triggered. A value of 0 means that as soon as one pixel is visible, the callback will be run. A value of 1.0 means that the threshold isn’t set. Default value is 0.
• lazyLoad: Enables lazy loading of images. Default value is true.
• explicitWidth: Determines whether the image wrapper should explicitly declare the width of the image or keep it fluid. Default value is false.
