Image Class version 2.3.3

General

• The fisheye PI was modified to include vertical bar characters at the beginning and end. These will appear between the fisheye and "<< previous items" and between the fisheye and "next items >>" on the TOP and BOTTOM of the results pages. Therefore customized templates, including collection specific templates, should have the vertical bars around the fisheye PI removed. This solves the problem of bars being displayed even when there are not enough results to warrant a fisheye. The few remaining chunks of "interface english" left in the code were shifted to the %gWords has h in imageclass.cfg. This change affected ImageClassUtils.pm as well.
• Image file dimensions for the view tab graphics were shifted to a global variable to accomodate size changes.

XClass version 1.0.0

• This is the first release of XClass. The current implementation of XClass is a prototype cross-class search application which sens a simple word or phrase query to each of TextClass and ImageClass and displays a simple result detailing the number of hits in each class and provides a link for the user to go to a given class and explore the result in more detail. XClass receives and ApplicationResult object from each class containing the result of the query. It is anticipated that this prototype will develop in functionality in subsequent releases.
