Properties of images and rollover images
You can change the properties of an image using the Image Edit area of the Properties Inspector (Window >
Properties) after selecting the image on the slide.
Image
Item Name Enter a unique name for the object. You can use this name when defining the visibility conditions for the
object.
Visible Deselect this option if you want the object to be invisible on the slide. Use the Show option to make the object
visible. For more information, see “Controlling the visibility of objects” on page 50.
Transparent Background Select the color filler icon. All occurrences of one particular color in an image can be made
transparent. For example, you can make all occurrences of red (#FF0000) transparent.
Reset To Original Size Restores the image to its original size.
Select Image From Library Click the folder icon. Select this option to reuse an image in your project file. Select the
image and click OK.
The Select Image from Library dialog box appears with the following options:
Import Import an image stored on your computer or on a network location.
Image Edit
Brightness The brightness of the image. When you increase the value for brightness, the selected image appears
brighter.
Sharpness Sharpening enhances the definition of edges in an image. Whether your images come from a digital camera
or a scanner, most images can benefit from sharpening. The degree of sharpening needed varies according to the
quality of the digital camera or scanner. Keep in mind that sharpening cannot correct a severely blurred image.
Contrast The contrast between the light and dark areas of an image. When you increase the contrast of an image, the
brighter areas appear brighter, and the darker areas appear darker.
Alpha The transparency of the image. At 100% Alpha, the image is opaque. At 0% transparency, the image is invisible.
Hue You can change the colors of an image by changing the values for its hue.
Saturation The intensity of colors in the image. When you increase the saturation value, you increase the intensity of
the colors.
Gray Scale In a basic sense, you can convert a colored image to monochrome using this effect. Grayscale mode uses
different shades of gray in an image. In 8-bit images, there can be up to 256 shades of gray. Every pixel of a grayscale
image has a brightness value ranging from 0 (black) to 255 (white). In 16-bit and 32-bit images, the number of shades
in an image is much greater than in 8-bit images.
Invert Color Inverts the colors in an image. When you invert an image, the brightness value of each pixel in the
channels is converted to the inverse value on the 256-step color-values scale. For example, a pixel in a positive image
with a value of 255 is changed to 0, and a pixel with a value of 5, to 250.
Flip Flipping an image produces its mirror image. You can flip an image vertically or horizontally.
Rotate Rotate an image either clockwise or counterclockwise 90 at a time.
Crop Click the crop icon. Crops the imagehandles of the rectangular box to select the area of the image that you want
displayed.
Fit to Stage Resizes the image to fit the dimensions of the slide.
