In Adobe Photoshop, save alpha channels or clipping paths to a totally blank image.
Place this picture on a page over text. Under Item> Clipping, select the channel or path from the Type drop-down menu and check Invert.
Do the same in the Runaround pane and click OK. The text should now flow inside the irregular path shape.
