Introduction

ScanW.Dll library is a wrapper COM object that eases the integration between VC++ source libraries
and VB code. The library includes four sub libraries:
SlibEx – Controls the scanner activity and contains the last scanned image in an internal memory. This
library controls the scanning settings such as scan size, color scheme and resolution. The scanned
image is loaded to an internal memory and can be saved to an external file in a bitmap format.
Ocr (In OCR version only) – Extract the textual data from the internal image.
IdData (In the ID version only) – Parse and refine the textual data extracted by the OCR. The data is
kept in internal variables ready to be exported to the application.
Cimage – Use for internal image manipulation such as rotation, color scheme modification, dpi
modification and image export to a file in various formats. This library can also be used for external
image files manipulation.
Each sub library can function as individual library regardless to the other libraries.
