To read a Digimarc
watermark:
1 Choose Filter > Digimarc > Read Watermark.
If the filter finds a watermark, a dialog box displays
the Digimarc ID, copyright year (if present), and
image attributes.
2 Click OK. If you have a Web browser installed,
click Web Lookup to get more information about
the owner of the image. This option launches the
browser and displays the Digimarc Web site, where
contact details appear for the given Digimarc ID.
Using rulers and the grid
Rulers and the grid help you position items (such
as selections, layers, and shapes) precisely across
the width or length of an image.
When visible, rulers appear along the top and left
side of the active window. Markers in the ruler
display the pointer’s position when you move it.
Changing the ruler origin (the (0, 0) mark on the
top and left rulers) lets you measure from a specific
point on the image. The ruler origin also deter-
mines the grid’s point of origin.
To show or hide rulers:
If the rulers aren’t visible, choose View > Rulers.
Choose the command a second time to hide the
rulers.
To show or hide the grid:
If the grid isn’t visible, choose View > Grid.
Choose the command a second time to hide
the grid.
To change the rulers’ zero origin:
Position the pointer over the intersection of the
rulers in the upper left corner of the window, and
drag diagonally down onto the image. A set of
cross hairs appears, marking the new origin on
the rulers. The new zero origin will be set where
you release the mouse button.
Note: To reset the ruler origin to its default value,
double-click the upper left corner of the rulers.
To change the rulers’ settings:
1 Do one of the following:
• Double-click a ruler.
• In Windows or Mac OS 9.x, choose Edit >
Preferences > Units & Rulers.
• In Mac OS X, choose Photoshop Elements >
Preferences > Units & Rulers.
2 For Rulers, choose a unit of measurement.
Note: Changing the units on the Info palette
automatically changes the units on the rulers.
(See “Using the Info palette” on page 17.)
3 For Column size, enter values for Width and
Gutter.
