Chapter 5 Working with Images, Shapes, and Other Objects 75

Automatically Reducing Images to Fit Your Slides

By default, if an image you place on a slide is larger than the slide, Keynote scales

down the image to t the slide, in a process called downsampling. A downsampled

image has fewer pixels than the original, so some of the image information is removed.

Images in JPEG format remain JPEG images; other formats are converted to TIFF. After

an image has been downsampled, you can’t restore it to its original size by clicking

Original Size in the Metrics inspector. To avoid downsampling and use images at their

original size, turn o automatic downsampling in Keynote preferences.

To turn o automatic downsampling of images:

1 Choose Keynote > Preferences, and then click General.

2 Deselect the checkbox “Reduce placed images to t on the slides.”

If you intend to greatly enlarge or reduce a graphic’s dimensions, consider converting

it to a PDF le before bringing it into Keynote. PDF les don’t lose their crispness when

they are signicantly resized. Other le types may not retain their clarity as well when

they are enlarged or reduced.

Tip: ∏ You can also convert an image on your desktop to a PDF le by using the Grab

application. Open Grab (it’s in the Utilities folder in the Applications folder on your hard

disk). Choose Capture > Selection, and then select the image you want to make into a

PDF le. Choose File > Print, and then click Preview to save the image as a PDF le.

Replacing Theme Images with Your Own Media

The photos you see featured in each Keynote theme are actually media placeholders.

By dragging your own images or movie les to these placeholders, your media is

automatically sized, positioned, and framed to t the slide’s theme.

To test whether the media on a slide is a placeholder, let the pointer rest over it

and see if a help tag appears instructing you to drag your own media le to the

placeholder.

Here are ways to work with media placeholders:

To replace a media placeholder with your own image, movie, or audio le, drag it from m

the Media Browser, the Finder, or another application to the placeholder.

To resize or reposition your image within a media placeholder, click the Edit Mask m

button that hovers over the image after you’ve dropped it onto the placeholder, and

then do any of the following:

To resize your image within the placeholder, drag the resize handle above the

Edit Mask button.

To reposition your image within the placeholder, position the pointer over the image (the

pointer may appear as a hand), and then drag the image to position it where you want.
