In-Depth Information
•
If you draw a path in Photoshop and save it with the image, InDesign can create a
clipping path from it.
•
If you paint an alpha channel in Photoshop and save it with the image, InDesign
can create a clipping path from it. An alpha channel carries transparent and opaque
areas and is commonly created with images used for photo or video compositing.
•
If the image has a relatively light or white background (or a relatively dark back-
ground if the subject matter is light), InDesign can automatically detect the edge
between the subject and the background and create a clipping path.
The image you will be placing (of three pears) doesn't have a clipping path or an alpha
channel, but it does have a solid white background that InDesign can remove.
Removing a white background using InDesign
Now you'll hide the white background that surrounds three pears in an image. You can use
the Detect Edges option of the Clipping Path command (Object > Clipping Path) to hide a
solid white background that surrounds an image. The Detect Edges option hides areas of
an image by creating a separate path around each distinct shape within the image.
1.
Navigate to page 7 of the document by double-clicking page 7 in the Pages panel.
2.
In the Layers panel, make sure that the Photos layer is selected so that the imported
image is placed on that layer. Choose File > Place, and double-click the file
10_c.psd in the Lesson10 folder.
3.
Position the loaded graphics icon ( ) outside the square on the left—to the left
and slightly below the top edge (make sure you are not placing the pointer in the
square itself), and click to place an image of three pears on a white background. If
you need to reposition the graphics frame to match the image below, do so now.
