Ann: WPViewPDF V4.0 - is available now

    • Offizieller Beitrag

    WPViewPDF is a component that allows you to load one or multiple PDF files and to display or print it/them as one.

    It is possible to export pages as bitmaps (PNG, JPEG) or as text. It is possible to add drawings which will be displayed and printed on top of the original data. The drawing objects can be moved and sized by the programmer in code or by the user in the end product.

    WPViewPDF V4 was developed to make it possible not only to view PDF files but also to really work with them.
    To make it easy to provide the user a powerful GUI a new action system has been integrated. It makes it possible to automatically initialize the menus and toolbars required.
    Most work has been put into the draw object and the new annotation system. Now it is possible to offer the user the possibility to add annotations to the PDF information.

    - All new action system. This allows it to create a GUI efficiently and quick.

    - new ActionMode: pan, select objects, draw etc.

    - add PDF annotations to a PDF file. Supported are at present:
    * highlight annotation
    * text background (the used can select text and the annotation will cover the area)
    * square annotation
    * symbols with Popups
    * squiggly underline annotation
    * text field annotations
    * checkboxes

    - move any existing annotation

    - delete any existing annotation

    - create draw objects on a "document layer". The document layer survives reloading a PDF file. This makes it possible to apply the same draw objects to various PDF files. With WPViewPDF PLUS it is possible to save the objects to XML and load as XML.

    - trigger mail merge events on marked text draw objects.

    - convert PDF into watermark: The user can select a PDF file and use certain PDF pages as background for the current PDF files. It is possible to reuse the same page on multiple pages.
    The Demo Setup can be downloaded here:
    https://www.wpcubed.com/pdf/download/w…demo-component/
    This setup contains the DLL and the VCL for Delphi and sample projects.

    FORMS FORMS FORMS :)

    4.5.2016 WPViewPDF 4.01.2 has been posted - the support for PDF forms has been much improved.

    You can create PDF forms with check boxes (various styles), edit fields, combo boxes and list boxes. You can even add masked edits and date drop downs! The user can use TAB to move to the next field and Ctrl+Tab to move to the previous - this works also over page boundaries.

    You need WPViewPDF PLUS to save PDF forms.

    The included program "PDFedit.exe" got a new form to create fields and widgets:

    • Offizieller Beitrag

    WPViewPDF V4.01.3 is available now.

    It is now possible to flatten the PDF annotations - they will be rendered onto the PDF page. After rendering they can optionally be deleted. It is possible to render widgets and/or popups and/or draw annotations.
    Link annotations will not be rendered and deleted.

    The new release improves the pdf form editing even more.
