Covers Control File
(Covers.cvt)
The Covers Control File provides
a link between the magazines indexed in one of the indexes and the associated
cover scans to be displayed with them. Each record in the file contains 4 fields,
separated (for historic reasons) by ␢.␢ rather than the more usual
~
- Image file name
This contains the file name of the associated cover scan without folder names
or extension. All such files must be jpeg files and are assumed to have an
extension of .jpg
- Publication Details
This contains the publication details of
the issue with which the cover scan is to be associated. By convention, cover
scans are added to the file even if there is no associated abbreviation for
the magazine and in this case a single lowercase 'x' is placed here (as that
will never match a real set of publication details). Note that the same publication
details may be associated with multiple image file names, in which case each
of the cover scans will be displayed with the issue in question.
- Source ID
This identifies the source of the image file. It currently will always contain
the value PSP which indicates the images come from the Galactic
Central website and are located in subfolders of http://www.philsp.com/data/images/
with corresponding thumbnails in subfolders of http://www.philsp.com/data/thumbs/
- Folder Prefix
This contains the folder prefix to be inserted between the image path names
listed above and the image file name to identify the full path to the image
concerned. These will always currently consist of the first letter of the
image file name followed by a /
