CDisplay is a freeware Comic book archive viewer and sequential image viewer utility for Microsoft Windows used to view images one at a time in the style of a comic book. It popularized the comic book archive file format. CDisplay was written to easily view JPEG, PNG and static GIF format images sequentially. The program was designed to be less general purpose than existing image viewer programs, and more convenient for simply viewing images sequentially.

Features

  • Loads JPEG, PNG, and static GIF images which are automatically ordered alphabetically and presented for viewing one at a time or two at a time.
  • The images may be viewed from a folder or collected in a .zip, .rar, .ace, or .tar archive file.
  • Page through the images sequentially and scroll around pages with single key presses.
  • Many automatic page sizing options including choices to display one or two pages at one time. Image resizing uses Lanczos resampling for the best picture quality.
  • No bloat caused by non-essential general purpose image processing features.
  • Users can view the pictures as full screen (with or without mouse pointer) or in a window.

Files

CDisplay supports Comic Book Archive files, archives of individual page images with the extension .cbr, .cbz, .cbt, or .cba; they are simply renamed RAR, ZIP, TAR, or ACE archive files.The standard icon for all comic file types extension is a comic balloon. The format was made popular by CDisplay but is now used by many other programs designed for reading comics.

CDisplay supports the display of JPEG, PNG, GIF, BMP, TXT, and also SFV files which confirm that the file is not corrupt, either directly or contained within archive files.

  • If a .txt file is within a folder or comic book archive file, it displays the comic's contents on file opening.
  • If a .sfv file is within a folder or comic book archive file, it verifies the SFV data to confirm that the rest of the content is not corrupted.
  • Automatic colour balance and yellow reduction if desired.

Limitations

CDisplay does not automatically add leading zeroes to sequentially numbered images inside Comic Book Archives. Consequently it reads files in the alphabetical order of 1, 10, 11, ..., 2, 20, 21, ..., rather than true numerical order. For files to be read in numerical order, leading zeroes must be added, 01, 02, ..., 10, ..., or 001, etc. if there are more than 99 pages.

CDisplay cannot display JPEG images more than 2999 pixels high or wide at their original sizes; it resizes such JPGs to fit within the 2999 pixel limit. The same limitation does not apply to PNGs, which are displayed using a third-party TPNGImage component by Gustavo Daud.

CDisplay will not open files with names containing non-ASCII characters, although the preview window in the advanced file selection dialog is able to display a thumbnail.

Development

The program was compiled using Borland C++ Builder 5.0 and runs on 32- and 64-bit versions of Windows platforms from Windows 98 onwards. CDisplay does not, and cannot, modify files. Some configuration data is written to the Windows registry.

The source code was not made available, and the program ceased to be maintained when the author died.[1]
