Description A comic book archive or comic book reader file (also called sequential image file) is a type of archive file for 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. OEB (Open eBook File) – This format was developed for ebooks under the Open eBook standard by the Digital community publishing forum (IDPF). At present, this format has been replaced with the file format EPUB. OEB Format (Open eBook File) combines the text in HML codes and other data sources (Graphics & Tables) into one digital archive. It is supported by Calibre, Sony Reader, Adobe Digital Editions. OEB files are endorsed under the copyright protection right of DRM (Digital Right Management). This format was developed for electronic books sold through online shops.
Technical details Comic book archive files mainly consist 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. In addition, 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.
