DEFINITION:
"Page-by-page is reading style that a page is not connected to adjacent pages, so that they can be displayed independently of one another."
For any title that in Page-by-Page format, images are divided into 3 types: Single, Double and Extra
Single Page
This is a typical case for a comic page. A single page must contain story content from the comic, and only has one-page width of a normal comic page.
In the INKR Comics app, all single pages are presented sequentially to the reader.
Double Page
Double pages are double the width of a normal comic page. Double pages contain story content seamlessly across the entire page.
In the INKR Comics app, double pages are displayed in their full width so that readers can enjoy them. They are presented sequentially along with normal pages to the reader.
Extra Page
Extra pages contain content that is not relevant to the story, such as additional artwork, sketches, author messages, thank you notes, table of contents, credits, recaps, or previews of other chapters.
Extra pages are displayed inside the “Credit & More” widget at the end of the chapter, regardless of their page order. This helps readers consume the main story of the title without being distracted by additional content.
Some series that have been published on INKR Comics, such as
Japanese Mangas: Attack on Titan, Fairy Tail, Fire Force....
