Last change on this file since 26731 was 26731, checked in by davidb, 10 years ago

Can now correctly obtain colours and size of text when generating Expeditee frames. Also accounted for when the web browser being used is Firefox (FF uses "700" instead of the word "bold" for font-weight). The width of text items is also calculated and written to Expeditee. Parameters have also been provided so the user can decide whether they want the correct font information and text width used or to just use default values.
