Create a new instance of Signature class and pass input document to it
Instantiate the ImageSignOptions object and specify image signature options
Call sign method of Signature class instance and pass ImageSignOptions to it

Image Representation of Document Pages

Apply digital signatures to a wide range of document formats and generate the image representation of the already signed document pages in PNG, JPG or BMP formats. You can easily preview the complete document as a whole or choose to display some specific pages based on page numbers or page ranges.

Using advanced document previewing features - easily hide digital signatures from the signed documents while generating the document preview.

What is DOCM file format?

The DOCM file format serves as a specialized variant of Microsoft Word documents, tailored specifically for creating and saving documents that contain macros within the Word application. Unlike regular DOC files that are intended for basic documents, DOCM files cater to documents incorporating macros.

Macros, composed of commands and scripts written in Visual Basic for Applications (VBA), empower users to execute more intricate automated tasks and functions. They prove particularly valuable in streamlining processes and automating repetitive activities, such as generating charts and formatting documents.

By saving a document as a DOCM file, users ensure that the macros they have created are included in the file and accessible when opened by others. Additionally, DOCM files provide an added layer of user protection by disabling all macros when the document is opened by someone else. This safeguard shields users from potentially malicious macros that could compromise the security and stability of their computer systems.

Furthermore, DOCM files retain compatibility with various versions of Microsoft Word, assuring users that macros will function correctly regardless of the recipient’s Word version. This compatibility facilitates seamless sharing and collaboration on documents containing macros.
