Xara LX has several ways of using objects to "mask" or "clip" other objects. You then see part of the objects through the mask.

image\BULLET.gif Intersect shapes: this uses an object as a "mask". Selecting this menu option discards those areas of selected objects not covered by the mask. The mask object disappears. See Intersecting shapes.

image\BULLET.gif ClipView: this uses an object as a "window" onto other objects. You can move or resize the window to change your view onto the masked objects. The window object remains visible. See Using ClipView.

image\BULLET.gif (for bitmaps) Convert to editable shapes: the bitmap appears within an arbitrarily shaped object. You can edit the shape of the object to mask unwanted areas of the bitmap. See Masking a bitmap.

Notes:

image\BULLET.gif You are not limited to using a single shape as a mask or window. You can also use groups, joined shapes or combined shapes.
