What if you need to crop a placed image or define an irregular shape that determines what part of the image shows through but also maintain the text file’s linked status? One solution is to draw and apply a clipping mask.

Clipping masks hide sections of an image without cropping the image. To create and apply a clipping mask, follow these steps:

1 Draw a shape or path over the image demarcating a crop area, as shown in Figure 3-8.Normally, this shape will be a rectangle, like the one shown in Figure 3-8, but it can be any shape or path.FIGURE 3-8: Drawing a clipping mask.

2 Select both the rectangle and the placed image by using Shift-click or any other selection technique, and then choose Object ⇒ Clipping Mask ⇒ Make.The result looks like a crop, but the placed (and linked) image only appears to be cropped. The entire placed image is still in the Illustrator document.If you want to display the entire image in your illustration, you can release the clipping mask by selecting the placed image and choosing Object ⇒ Clipping Mask ⇒ Release.

3 To change the location of the clipped image, choose Object ⇒ Clipping Mask ⇒ Edit, and select and move the mask, as shown in Figure 3-9. To edit an existing clipping mask for a selected object, choose Edit ⇒ Clipping Mark ⇒ Edit Contents.
