The CBx extension generates previews and thumbnails for uploaded Comic Book Archive files of the types cbz and cbt, and shows a paginated preview layout in file-pages. It makes Comic Book Archives behave like PDF and multi-page TIFF files as handled by extension:PDFHandler and Extension:PagedTiffHandler respectively.
Comic Book Archive files are a de facto standard utilizing common file archive formats files, sometimes augmented with metadata, and having custom extensions of cbx where x denotes the archive format.

[edit]
Note: The required software above must be installed first.
Usage
[edit]- A user can display CBx files as an image, showing a single page at a time, like so: [[File:myCbxFile.cbz|page=1|600px]]. The page and size parameters are optional; the default page is page #1. Instead of a size-parameter, you can also use the thumb-parameter, with or without captions: [[File:myCbxFile.cbz|page=1|thumb|My CBZ]].
- Because CbxHandler extends ImageHandler, you can use all the arguments that you would for an Image -- for example: thumb, right/left, caption, border, link, etc.
- If you would like to present a 2-page cbz, for example, do the following: [[File:myCbxFile.cbz|page=1]] [[File:myCbxFile.cbz|page=2]]
- The main usage of the CBxHandler extension is without user interaction. If you upload a new cbx file, the metadata will be stored in the database, and then this file can be shown in a multipage preview layout like the djvu handler does. Without this extension, cbx will not display properly when uploaded.
Configuration
[edit]- Variables below are not specific to this extension
- Enable ImageMagick, if you haven't already:
$wgUseImageMagick = true; $wgMaxShellMemory- memory limit for convert, cbx-info and cbx-extract. The default value might be too low.
Debugging
