Microsoft Office Document Imaging 2003 (MODI) Viewer OCX Control


Overview

The Microsoft Office Document Imaging 2003 (MODI) Viewer OCX Control can be used to display images and perform minor image editing functions. Viewing functionality includes panning, scrolling, zooming and selecting both image data and text (OCR has to be performed first).


Referencing the MODI Viewer OCX Control in a Microsoft Visual Basic Project
To include the Microsoft Office Document Imaging 2003 (MODI) Viewer OCX Control into a Microsoft Visual Basic project, use the Project | Components menu item and select Microsoft Office Document Imaging 11.0 Type Library (mdivwctl.oca). By including the Viewer OCX Control into the project, a reference is automatically added - making the entire Object Model available to the programmer. Note that the Viewer OCX Control corresponds to the MiDocView Object in the Microsoft Office Document Imaging 2003 (MODI) Object Model.

Using the MODI Viewer OCX Control

The Microsoft Office Document Imaging 2003 (MODI) Viewer OCX Control can be used to display image files by simply setting the control's FileName property to the name of an existing TIFF or MDI image file. Alternatively, the Document property can be set to a document that has already been loaded into memory.

The user can select either image data or text from a displayed image. In order to go into 'Select' mode, set the ActionState property to miASTATE_SELECT. When the user uses the mouse to select a portion of the image, a red bounding rectangle appears. The text within the bounding rectangle can be accessed through the TextSelection property (which returns an IMiSelectableItem object) while the image data within the bounding rectangle can be accessed through the ImageSelection property (which returns an IMiSelectableImage object).
