Note:
The options in this dialog box only apply when saving a form design as a PDF file. They do not apply to PDF and XDP form designs being rendered through LiveCycle Forms ES.
Embeds accessibility information within the saved PDF file. This option is only available when publishing in PDF.
Creates a log file of the saved file. The log file is placed in the same directory as the saved form. This option is only available when publishing in PDF.
Saves forms as static PDF, based on the Acrobat and Adobe Reader target version specified. Static PDF forms render once and are displayed on the client in the Acrobat or Adobe Reader target version. They are not rerendered in response to user interaction. The PDF form may have been designed with a flowable layout, but when the static PDF form is created, its layout is fixed and the resulting PDF form will not rerender on the client. Static PDF forms can be interactive or non-interactive.
Saves forms as dynamic PDF, based on the Acrobat and Adobe Reader target version. The form design can contain dynamic elements. Dynamic PDF forms render on the client in Adobe Reader and, depending on the end-user interactions, can rerender on the client several times. Changes to the appearance of an object are possible in Adobe Reader because Adobe Reader has enough information to rerender the final output. For example, objects can change color, pagination can change, and objects can appear or disappear. If an end user clicks a button that adds a new row to a table, the form is rerendered in Adobe Reader.
