Watermark: adjusts the brightness of the image making it
suitable to be used as a watermark. For more information on
creating watermarks, refer to Chapter 2.
Adjusting the color
Clicking the color adjustment button on the Picture toolbar opens
the color adjustment dialog box, shown in Figure 62.
Use this dialog box to modify the individual color components of the
image (red, green, blue) as well as the brightness, contrast, and
gamma of the image. If the result is not satisfactory, press
Control+Z
to restore the default values.

adjustment dialog box
Setting the object transparency
Modify the percentage value in the Transparency box on the
Picture toolbar to make the image more transparent. Note that this is
different from the transparency settings for a line or a shape
(described in Chapter 5).
Adjusting the line, area and shadow settings
These settings are not very commonly used for images, with the
exception of the shadow setting that applies a shadow to the image.
Cropping pictures
Impress 3 provides two ways to crop a picture: interactively (new in
OOo 3) or using a dialog box. The interactive method is easier to use,
but the dialog box provides more precise control. You can use both
methods: first cropping interactively, then using the dialog box to fine
tune the result.
