If you customize Crystal reports or the BusinessObjects Enterprise web
desktop extensively, you may encounter other accessibility issues. For online
resources that provide comprehensive accessibility guidelines, see
Re
sources . The following list provides some common accessibility issues that
may cause problems when you customize Crystal Reports or BusinessObjects
Enterprise content.
• Frames
Frames should be clearly labelled, for easier identification and navigation.
Provide text at the top of the frame that describes its purpose. For
example, if a frame provides a list of links to different countries, you can
clarify its purpose clear by adding text to the frame, such as a title
("Countries") or short instructions ("Click a country for details").
• Style sheets
If you have a visual impairment, you can create a style sheet with specific
viewing preferences to accommodate the disability. For example, you
could create a style sheet that displays all web pages in a large font with
white characters on a black background. Users cannot apply personalized
style sheets to Crystal reports, but the viewers provide a Zoom button
that enables people with visual impairments to increase the magnification
to suit their needs. You can also allow users to choose from different
formatting options using conditional formatting. For details, see
Accessibility and conditional formatting .
• Scripts
If you modify Crystal content to include a script that displays content or
an interactive object, ensure that the script is identified by text that conveys
the purpose of the script. Make sure that pages with scripts are still usable
when the scripts are turned off or unsupported. For more information
about scripts and accessibility, see
Resources .
• Image maps
Server-side image maps identify active regions using coordinates, which
are not meaningful to a screen reader. Client-side image maps provide
better accessibility because you can assign a link or URL to each active
region within the image map.
• Electronic forms
Electronic forms can present difficulties for screen readers, and must be
set up carefully. When you label a component in a form, ensure the label
