Appendix F: Accessibility Support
G.1 Accessibility and SVG
Drawings done in SVG will be much more accessible that drawings done as image formats
for the following reasons:
- Text strings in SVG are represented as regular XML character data rather than bits in an image.
- At any place in the SVG hierarchy, a drawing can include a long set of
and/or a short description
in the form of a title. Both of these features can be used to help the visually
impaired interpret both the intent and specific content of a drawing. The drawing
can be architected such that there is a single description for the drawing as a whole
or there are multiple descriptions which are distributed within the drawing
and describe each separate component within the drawing.
- Because of SVG's support of Cascading Style Sheets Level 2 (??? need to add link),
there will be the ability to set up personal style sheets to adjust the color
contrast of graphic elements.
- Because SVG documents are scalable, people with partial visual impairment will
be able to zoom in on graphics for easier viewing.
(Additional information on accessibility is forthcoming.)
