By default, the IBIS-PH system delivers JPEG chart and map graphics to
your browser. If you want to have interactive charts and maps or if
you are experiencing problems displaying charts and maps then see the
IBIS-PH Graphic Display
Preference page for options and more information.
All IBIS-PH pages use a font size based on the browser's font size setting
(typically located via the "View/Text Size" menu selection). This allows
the font size of the IBIS-PH pages to be increased or decreased by simply
changing this setting. Note that this setting will/could effect other
pages viewed within the browser if that page has been coded to use the
browsers font size setting.
