Image tooltips

The Image tooltips function, accessible under System/Utilities/Administration tools, ensures all images/icon’s used by RefTracker have appropriate alternative text (to meet WCAG 2.0 compliance rules) and helpful mouse-over tooltips. This function allows you to change the text provided as the alternative text and tooltip when that is necessary for your organisation.

Where no meaningful text has been provided for an image, the Alternative text in this table may be blank. This is by design, as a blank value in this table will result in the screen reader announcing nothing as the Alternative text for that image. The WCAG 2.0 compliance rules state that simple defaults like reading out the file name, are inappropriate.

Note that in some cases, RefTracker programmatically sets the tool tips for an image according to its use and when that occurs the programmatic setting overrides any setting in this table. Also some images are associated with code tables and where that is the case their tooltip/alternative text is provided by the description associated with that icon in that code table (e.g. the Priority and Request group code tables).

The images used in RefTracker are presented in groups according to the subdirectory in which they are stored. Select the subdirectory you want to view by using the “Select image group” drop down in the top right hand corner of the screen.
Local is the directory where you can load your own images, such as for corporate logo’s. 
Main is the directory containing all the images provided by RefTracker for use within it.

Importantly the local directory allows you to assign appropriate text to any images that you load into this directory (such as your organisation’s corporate logo used in the RefTracker header).

Because the colour of the images can be changed using the Colour scheme editor, there is a source directory that hold the base image.

The imagesource.xml file (in the config folder) is used to map the source image to a designated RefTracker image.

When the Colour Scheme Editor saves changes, the images will be regenerated according to the instruction in this file using the specified source image.
