Clipping Path is an initial technique commonly used to take out targeted object from its background. A great tool in Photoshop, “Photoshop Pen Tool” is used to create an outline around an object is called Clipping Path when its active.
Can I combine alpha transparency with a clipping path on the same image in InDesign?
When you invoke the Object > Clipping Path command in InDesign, it makes a path according to the basis you choose from the Type menu in the Clipping Path dialog. If the image already contained transparency via Photoshop layering, or an "alpha channel," that transparency, is of course, also preserved. So yes, you can have native transparency plus an InDesign-generated clipping path on the same image.
