Each placeholder has an id (a low integer value). The ids are unique across a single layout. The function uses the placeholder's id to reference it. Different from a ph label, the id is auto-assigned by PowerPoint and cannot be modified by the user. Use layout_properties() (column id) and plot_layout_properties() (upper right corner, in green) to find a placeholder's id.
ph_location_id(id, newlabel =NULL,...)
Arguments
id: placeholder id.
newlabel: a new label to associate with the placeholder.
...: not used.
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.
