CDisplay is a freeware 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's inspiration and implementation was partly because already existing programs were too general purpose and thus were awkward to use when simply viewing images sequentially.
- 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.
CDisplay supports Comic Book Archive files, which have the extension .cbr, .cbz, .cbt, or .cba and are simply renamed RAR, ZIP, TAR, or ACE files, respectively. The files are archives of individual page images with a new extension for convenience. 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.
- 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.
In creation of Comic Book Archive files containing sequentially numbered files (page 1, page 2...), CDisplay does not currently support the supposition of leading zeroes. As such, it will read files as 1, 10, 11, ..., 2, 20, 21, ..., rather than in the order of 1, 2, 3, ..., 10, 11..., which is the more useful interpretation. To get around this minor flaw, leading zeros up to the highest digit in the sequence must be added explicitly. For example, the first page of an 80 page document would be 01, and for an 800 page document it would be 001.
The program was compiled using Borland C++ Builder 5.0 and runs on various Windows platforms including Windows 98, NT, XP, Vista, and Windows 7. CDisplay has no write capabilities, and therefore files are left untouched. A small amount of configuration data is written to the Windows registry.
CDisplay is no longer actively maintained, as the original author died, and the source is not available.
CDisplayEx is a development of CDisplay and added new features:
- Correctly sort the file names even if the names contain numbers.
- Support for multi-monitor display.
- A plugin to display the covers in Windows Explorer
