In AEM forms, PDF forms rendered with the assistance of
Forms, Output, or Form Data Integration (FDI) services have the
appearance that is similar to PDF forms in Acrobat X. However, if
you are upgrading from the previous version of AEM forms, and would
like to retain the older appearance of PDF forms, you can set a service-level
configuration option for the Forms, Output, and FDI services.
For the Forms, Output, or FDI services, when the value of this
option (Appearance Compatibility Mode) is set to 9, all PDF forms
rendered using the service appear in the legacy appearance. Any
other value set for this option results in generated PDF forms appearing
with the look and feel enabled by AEM forms.
In the Components
view, drill down to
Right click FormsService1.1 and select Edit Service Configuration.
On the Configuration Settings dialog, edit the Appearance
Compatibility Mode option to set the version of Acrobat whose appearance
mode is to be configured.
Click OK to complete the setting.
