Explain please

Can anyone explain the meaning of the following sentence: A black cutout of a human shadow oozed across the first page of Chapitre Quatre.

Unless Chapitre Quatre is Chapter 4 of an e-book, you have a remarkable graphics accomplishment at this location. A black cutout is presumably meant to indicate a silhouette, so the human shadow would be represented in silhouette. If it oozed its way across the page, we are talking either about an e-book (electronic book) or a miracle.
