The function will return a list that complies with expected format for argument location of function ph_with.

ph_location(
  left = 1,
  top = 1,
  width = 4,
  height = 3,
  newlabel = "",
  bg = NULL,
  rotation = NULL,
  ln = NULL,
  geom = NULL,
  ...
)

Arguments

left, top, width, height

place holder coordinates in inches.

newlabel

a label for the placeholder. See section details.

bg

background color

rotation

rotation angle

ln

a sp_line() object specifying the outline style.

geom

shape geometry, see http://www.datypic.com/sc/ooxml/t-a_ST_ShapeType.html

...

unused arguments

Details

The location of the bounding box associated to a placeholder within a slide is specified with the left top coordinate, the width and the height. These are defined in inches:

left

left coordinate of the bounding box

top

top coordinate of the bounding box

width

width of the bounding box

height

height of the bounding box

In addition to these attributes, a label can be associated with the shape. Shapes, text boxes, images and other objects will be identified with that label in the Selection Pane of PowerPoint. This label can then be reused by other functions such as ph_location_label(). It can be set with argument newlabel.

Examples

doc <- read_pptx()
doc <- add_slide(doc)
doc <- ph_with(doc, "Hello world",
  location = ph_location(width = 4, height = 3, newlabel = "hello") )
print(doc, target = tempfile(fileext = ".pptx") )

# Set geometry and outline
doc <- read_pptx()
doc <- add_slide(doc)
loc <- ph_location(left = 1, top = 1, width = 4, height = 3, bg = "steelblue",
                   ln = sp_line(color = "red", lwd = 2.5),
                   geom = "trapezoid")
doc <- ph_with(doc, "", loc = loc)
print(doc, target = tempfile(fileext = ".pptx") )
