OptionalbasemapPer-slide basemap override (multi-manifest slideshow tours): any
map_type value or IIIF info.json URL. Absent keeps the story
basemap. The layer is cached, so returning to a slide is free.
Honored only with slideshow_source.
OptionalfilterPer-slide image grading (slideshow filters): applied as a CSS
filter() on the map viewport. All fields optional; absent means
unfiltered. hueRotate is degrees (-180..180), blur is CSS pixels.
Honored only with slideshow_source.
OptionaliconOptionaliconOptionalimageOptionallatOptionallineOptionallonOptionalmaskSpotlight mask (slideshow passepartout): normalized viewport
fractions {x, y, w, h} (0..1) left visible while the rest is dimmed
with color. invert dims the inside instead of the outside.
Absent means no mask. Honored only with slideshow_source.
OptionalregionImage region [x, y, w, h] in image pixels (IIIF xywh convention,
slideshow-style image stops): the view fits the region on
navigation; image maps (map_type: "iiif" + map_as_image) only.
OptionalrotationView rotation in degrees clockwise (slideshow rotation). Applied to
the map view on navigation; absent means north-up (0). Image and geo
maps alike; purely presentational. Honored only with
slideshow_source.

Public data and options types for constructing a StoryMap.
The data types are exported rather than only referenced: they are what a host actually types its document and options with, and TypeDoc warns about a documented member whose type it cannot link.
