Annotation APIs

This VB.NET Word annotation control SDK actually integrates .NET Imaging Annotation SDK Library and VB.NET Word Reading Component Add-on. Thus, from this VB.NET Word annotator library SDK, you can find mature VB.NET APIs to decode, encode and annotate source Word .docx document file.

Using the following VB.NET Word annotating APIs, you can easily add & burn specified annotation image on selected Word document page. asp.net add text to pdf file, open word document in asp.net mvc, preview pdf in asp.net mvc, mvc pdf viewer free, pdf viewer in asp.net using c#, asp.net display image from base64 string, asp.net pdf editor.

Private Function AddFloatingItem(item As BaseItem) As Integer Implements DOCXPage.AddFloatingItem
End Function
Private Sub MergeItemsToPage() Implements DOCXPage.MergeItemsToPage
End Sub

Tips: to help you have a deep understanding of above VB.NET Word annotating APIs, we will make some introductions for some programming classes and the working principle of this Word annotation component SDK for VB.NET first.

DOCXDocument: within the whole VB.NET Word editing control add-on, one in-memory Word document file will be represented as a DOCXDocument object. Therefore, this DOCXDocument class can be counted as a high-level model to display .docx document file in .NET developing application.
DOCXPage: as for the page contained in DOCXDocument file, RasterEdge uses one DOCXPage instance to display it. Thus, in general, one DOCXDocument object contains a list of DOCXPage instances.
Word annotating process: when you create and add a fully customized annotation image to selected DOCXPage object, this Word annotation control in VB.NET will automatically create a REImage and burn it at defined Word location. As the Word annotation burning process fully implements Word coordinates system, developers only need to specify the coordinates of position and annotation size in local settings. Then they can fully complete VB.NET Word annotating process.

VB.NET Demo Codes

The available types for this VB.NET Word annotation control add-on contains callout annotation, embedded image annotation, ellipse annotation, free hand annotation, free hand line annotation, hotspot annotation, hotspot free hand annotation, line annotation, lines annotation, rectangle annotation, rubber stamp annotation and text annotation.

And here we list separate VB.NET programming codes for each supported Word annotating type. If you have any problem in testing following VB.NET Word annotation sample codes, please free to contact our technical support team via E-mail. To view sample C# code for Word annotating application, please follow this link to C#.NET Word annotating tutorial.
