DYNAMIC DISPLAY METHOD OF MULTI-LAYERED PDF DOCUMENTS

摘要

A method for dynamic display of at least one layer in a PDF document, comprising the steps of setting at least one criterion for at least one property of a trigger to change a display state of the at least one layer of the PDF document to another display state of the at least one layer of the PDF document, creating a script that can be processed by a PDF document reader and that contains the at least one criterion for the at least one property of the trigger, and embedding the script in the PDF document, wherein when the PDF document is opened by the PDF document reader, the script causes evaluation of the at least one property for the trigger, and if the at least one criterion for the at least one property of the trigger is met, then the script causes a change of the display state of the at least one layer of the PDF document.

1. A method for dynamic display of at least one layer in a PDF document, comprising the steps of:
setting, via a server, at least one criterion for at least one property of a trigger to change a display state of the at least one layer of the PDF document to another display state of the at least one layer of the PDF document; creating, via the server, a script that can be processed by a PDF document reader and that contains the at least one criterion for the at least one property of the trigger; and embedding, via the server, the script in the PDF document, wherein when the PDF document is opened by the PDF document reader running on the server or another computer, the script causes evaluation of the at least one property for the trigger, and if the at least one criterion for the at least one property of the trigger is met, then the script causes a change of the display state of the at least one layer of the PDF document.
