Let’s discuss the user preferences JSON input in more detail:

The eViewer v7 provides the access to the user to shuffle or hide the functionalities with their relevant icons. They can manage to rearrange or reorganize the icons as per their choice.

• Repositioning of Buttons:

  User can change the positioning of buttons. They can shift a button and place them in any other toolbar.

• Reorganizing of Buttons:

  User can reorganize the icons. They can modify the sequence of the buttons within the toolbar.

User needs to follow the pattern of the JSON input object, and provide the values accordingly.

NOTE:

• Upload document, Insert document and Scan document cannot be reshuffled because of the URL update. If user tries to rearrange any of them, then these features will be non-functional.
• All buttons can be hidden, except settings button. It will be visible with an empty frame if all the three attributes (i.e. userPreferences, exportDocument, print) are hidden.
• If the client desires to remove the whole settings panel, then he has to remove the settings attribute from the JSON input.
• All other icons can be repositioned and reorganized, except right document toolbar, that includes page navigation. It should be on a fixed position.
