Timing In Canvas, the duration of an effect can be set on a scale that goes from ‘min’ to ‘max’. That settings will be used in a PDF file as a time that goes from 0.5 seconds up to 4.0 seconds. Since there is no option for setting the length of time an individual slide will stay visible during a slide show, a default time of 15 sec- onds will be used; i.e., if the user doesn’t go to the next slide, the next slide will come up automatically after 15 seconds. Exporting hypertext links and URLs The PDF Export filter now supports all links that have been set through the URL palette. Links to individual pages of a multi-page document will result in the creation of hypertext links within the PDF file. Links to external HTML or PDF files are also supported. It should be noted that PDF supports rectangular (orthogonal) hot- spots only. This means, that if a URL is assigned to a rotated text object, the bounding box of the text will be defined as the hot-spot area. This should not be a problem if there is just one such link on a page. However, you should be aware that when more than one rotated text (or other not rectangular objects) with a URL are used on a page, their bounding boxes may intersect each other. This may cause links that are located beneath another’s bounding area to not work as expected. More details about how to use URLs can be found in the PDF docu- mentation.
