Type Alias PresentationOptions

PresentationOptions: Pick<ImageBlock, "layout" | "width">

How a block sits in the flow of the page. layout floats or aligns it and width is its percentage of the column. The kinds the editor lays out this way take these beside their own options; a new infobox written without them floats right at 40, every other kind is full width, and on a replace or an update an omitted field keeps the value the block already has.

const options: PresentationOptions = { layout: 'wrapRight', width: 40 }
