Defined Slide Transitions

Slide transitions define the transition to show when moving to the slide. slide_transition_generic() allows the user to create and pass new types of transitions. Otherwise, most standard transitions are already defined as slide_transition_*() to allow the user to easily define a transtion and any other assets the transition may need.

slide_transition_generic(
  type,
  transition_type_xml,
  speed = c("med", "fast", "slow")
)

slide_transition_blinds(orientation = c("horz", "vert"), speed = "med")

slide_transition_checker(orientation = c("horz", "vert"), speed = "med")

slide_transition_circle(orientation = c("horz", "vert"), speed = "med")

slide_transition_comb(orientation = c("horz", "vert"), speed = "med")

slide_transition_cover(
  direction = c("d", "l", "r", "u", "ld", "lu", "rd", "ru"),
  speed = "med"
)

slide_transition_cut(black_screen = FALSE, speed = "med")

slide_transition_diamond(speed = "med")

slide_transition_dissolve(speed = "med")

slide_transition_fade(black_screen = FALSE, speed = "med")

slide_transition_newsflash(speed = "med")

slide_transition_plus(speed = "med")

slide_transition_pull(direction = c("ld", "lu", "rd", "ru"), speed = "med")

slide_transition_push(direction = c("d", "l", "r", "u"), speed = "med")

slide_transition_random(speed = "med")

slide_transition_randomBar(orientation = c("horz", "vert"), speed = "med")

slide_transition_split(
  split = c("in", "out"),
  orientation = c("horz", "vert"),
  speed = "med"
)

slide_transition_pull(direction = c("ld", "lu", "rd", "ru"), speed = "med")

slide_transition_wedge(speed = "med")

slide_transition_wheel(spokes = 4L, speed = "med")

slide_transition_wipe(direction = c("d", "l", "r", "u"), speed = "med")

slide_transition_zoom(zoom = c("in", "out"), speed = "med")

slide_transition_null()

Arguments

type

string defining the slide transition type

transition_type_xml

string defining the OOXML of the transition type

speed

speed of the slide transition - med, fast, or slow

orientation

specify "horz" or "vert", defining the orientation of a transition

direction

specify the direction of transition, with possible values of d (down), l (left), r (right), u (up), ld (left down), lu (left up), rd (right down), ru (right up). Not every transition allows every direction. Check the available default values to see what values can be used for every transition

black_screen

boolean identifying if the transition starts from a black screen and then transitions to new slide over black

spokes

specify the number of spokes in the wheel; values are integers.

zoom, split

specify the direction of zoom, "in" or "out"

Examples

pptx <- example_pptx()

## add a transition to a new slide
pptx <- pptx |>
   add_slide(
     layout = "Title and Content",
     transition = slide_transition_checker()
   )

## Update/add transition to n existing slide
pptx <- pptx |>
   update_slide(
     index = 1,
     transition = slide_transition_dissolve()
   )
