CDisplay is a free sequential image viewer utility for Microsoft Windows used to view images one at a time in the style of a comic book. 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.
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 uses Comic Book Archive files, which have the extension .cbr or .cbz and are simply renamed RAR or ZIP files, respectively. The files are archives of individual page images with a new extension for convenience. The standard icon for cbr and cbz 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 and TXT and also SFV files to confirm that the file is not corrupt, either "loose" or contained within RAR or ZIP files, as above.
- If a .txt file is within a folder or .CBR file, it displays the comic's contents on file opening.
- If a .sfv file is within a folder or .CBR 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.
Development
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 by the original author.
CDisplayEx
CDisplayEx is an open source clone which added new features. The latest available version is 1.8[1][2]. The source is available via Subversion on Sourceforge; however, after revision 118 (roughly corresponding to version 1.8) project files were removed from the repository and it appears development has ceased.
It supports the following file formats:[3] Comic Book Archive files (CBR, CBZ, CBT, CB7), RAR, ZIP, TAR, LZH, ARJ, CAB, GZ, BZ2, 7Z, JPEG, JPG, PNG, GIF, BMP, PDF and DJVU.
