When it comes to presentations, the old adage of “A picture is worth a thousand words” is sacrosanct. Nothing gets the point across like a compelling image. So it’s quite reasonable to expect automations of Keynote to encounter plenty of image-based tasks. Not to worry, the AppleScript support in Keynote provides ample controls for creating unforgettable presentations.

Keynote Scripting Terminology for Images

Documents created by any of the iWork applications, Pages, Numbers, or Keynote, can incorporate a common set of elements, including images, shapes, lines, tables, charts, movies, and audio clips. To AppleScript and the built-in scripting support of the iWork applications, these elements are considered iWork Items, and share a common set of properties, detailed in the iWork Item class from the iWork Suite:

The iWork Suite iWork item Class

iWork item  [inh. iWork item ] : An item which supports formatting.


contained by slides, document.

positionpoint ) : The horizontal and vertical coordinates of the top left point of the iWork item.

widthinteger ) : The width of the iWork item.

The properties in the iWork item class can be accessed and changed for any of the common iWork elements. For example, a script can get or set the position of a movie, or image, or shape, or any of the common elements.

In addition to sharing a common set of properties with the other iWork elements, each iWork element has its own set of properties, particular to that element. For example, the element-specific properties of an image are detailed in its dictionary listing, found in the iWork Suite:  (⬇ see below )

descriptiontext ) : Text associated with the image, can be read aloud by VoiceOver.

file nametext or file ) : When used with the get command, the value of this property is the file name of the image file currently displayed in the image container. When this property is used with the set command, the value of the property is a file reference (in HFS alias format) to the image file to be used to replace the currently displayed image.

opacityinteger ) : The opacity of the image, in percent (0 to 100).

Adding an Image to a Slide

The following script demonstrates how to use the make command to create a new image item on a slide, and then manipulate its basic sizing properties to adjust the image to encompass the entire slide, as shown in the screen capture shown below:
