Paper Comic Book is one of the templates you can use when you use the Overlay Tool.
When you add a page based on this template, there are two Paper Comic Book pages you can use. One is a full page image with no margin. The other is a full page image with no margin but with a text footer over the image.
You put the words for the page in speech bubbles, text blocks or captions. You can move them around on the image.
Images are sized to fill the page vertically, so your image can appear to have the sides cropped.
The front cover page has a black background. As a result, you will not see pictures or lettering that are also black, such as images from the Art of Reading.
