| Format introduction | A comic book archive or comic book reader file (also called sequential image file) is a type of archive file for the purpose of sequential viewing of images, commonly for comic books. The idea was made popular by the CDisplay sequential image viewer; since then, many viewers for different platforms have been created. | The Portable Document Format (PDF) is a file format used to present documents in a manner independent of application software, hardware, and operating systems. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it. |
| Technical details | Comic book archive files mainly consist of a series of image files, typically PNG (lossless compression) or JPEG (lossy compression) files, stored as a single archive file. Occasionally GIF, BMP, and TIFF files are seen. Folders may be used to group images. Comic book archive files are not a distinct file format; only the file name extension differs from a standard file of the given archive type. | The PDF combines three technologies: A subset of the PostScript page description programming language, for generating the layout and graphics. A font-embedding/replacement system to allow fonts to travel with the documents. A structured storage system to bundle these elements and any associated content into a single file, with data compression where appropriate. |
