Fetches the raw page-element list from the Google Slides API and returns the
entry whose objectId matches x@element_id. This is the single point of
API contact for all element readers; all other getters (get_position(),
get_text(), etc.) call get_raw() first and then parse the result
locally.
The slide's page data is cached with a 15-second TTL by
presentation$get_page_raw(), so repeated calls within the same session
do not necessarily trigger an HTTP request.
Examples
if (FALSE) {
ps <- register_presentation(id = "YOUR_PRESENTATION_ID", set_active = FALSE)
slide_obj <- on_slide_number(1, ps)
el <- get_elements(slide_obj, type = "text")[[1]]
raw <- get_raw(el)
names(raw)
}
