ph_location_label: Location of a named placeholder

In davidgohel/oxbase: Manipulation of Microsoft Word and PowerPoint Documents

Location of a named placeholder

Description

The function will use the label of a placeholder to find the corresponding location.

Usage

ph_location_label(ph_label, newlabel = NULL, ...)

Arguments

ph_label	placeholder label of the used layout. It can be read in PowerPoint or with function layout_properties() in column ph_label.
newlabel	a label to associate with the placeholder.
...	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.
