WPViewPDF PLUS is a versatile and powerful component to not only view PDF files directly in a program, but also manipulate it in various ways. It is based on the PDF viewing component WPViewPDF and has all its capabilities, but it can also save new PDF files.

Functionality of the PLUS Edition

• "merge PDF files" - if multiple PDF files has been loaded a new file with the contents of all the PDF files will be written
• "delete pdf pages" - if pages were marked to be deleted they will not be written and so removed from the PDF.
• "extract PDF pages" - selected PDF pages can be save to a new PDF file.
• "stamp PDF files" - text, image and simple graphics can be applied to the PDF pages.
• New, empty pages can be added and the page order can be changed
• Special draw objects can be added to the PDF
• Text can be interactively highlighted and the highlight annotation will be saved
• Annotations of a PDF file which was loaded can be modified
• Fields can be added to the AcroField structure of a PDF form
• Field widgets can be added to a PDF: text, memo, checkbox, combobox and listbox types are supported.
• Other PDF files can be reused as watermark for the current PDF file
• When saving the PDF the pages can be scaled to defined dimensions
• Encryptions can be added
• "Flatten" PDF Forms - you can load PDF forms which contain annotations and save them into new PDF files with the annotation "appearance streams" permanently applied to the PDF pages.
