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.

Retrieving information from ID cards
Retrieving the data from an id card involves 4 steps:
Loading the internal image. Scanning the ID card in True color and 300 dpi, 2.2 x 3.6 inch does this.
Processing the internal image –use ProcState to activate the OCR on the scanner’s internal image.
Retrieve the data –use RefreshData function to retrieve the detected data
Export the internal image to a file in the proper dpi and color scheme.
IMPORTANT:
The internal image is overwritten in every new scan. It is the application responsibility to make sure
that the scan is performed in the proper setting (True color, 300 dpi, 2.2 x 3.6 inch). Failing to do so
may result with bad data retrieval.

Licensing
Each library mustto be initialized with a license number prior to usage using the Init() function of each
library. Failing to initialize the library will block the access to the library functionality. There are two
types of licenses:
Temporary License: Using this type of license common for library evaluation. This type of license
normally expires after 60 days. A temporary SDK license can be obtained fromhttp://id-
scan.com/developer
Permanent License: Unique key that is used to activate the library with no time limit and also used to
identify the customer when calling Card Scanning Solutions for customer support.
The software dealer supplies the permanent license key.
Distribution
To install the SDK files at destination computer you just need to copy all the SDK files that are in the
SDK installation folder to the destination computer.
There are some files that will need to be register on the destination computer such as COM\ActiveX
objects, install these files at the end of the SDK files installations since it will need the none
COM\ActiveX files to exist before register.
Here is a list of the files that need to be register:
ScanW.dll (Com object)
ScanWEx.dll (Com object)
ScanX.dll (ActiveX object) mostly used for VB scripts
Note:
If you don’t use the COM interface in your application and use the SDK files directly like in VC++
then you don’t need to install these files on the destination computer.

Library Properties and Methods
Library SlibEx: General Functionality
SlibEx library is used to scan documents and load their image to the internal image container. The
library also saves the scanned image to an external bitmap file. The library sets and retrieves the
scanners properties (such as scanning size, resolution and color scheme). The validity of all operations
on properties or functions is reflected on the property LastErrorStatus. This property automatically
reset upon reading.
Important: Some scanner functions may take several seconds to execute (such as Scan or Clean).
While executing lengthily function one should not try to execute a second scanner function until the
previous function has returned. Failing to follow this rule may cause software\hardware exception.
SlibEx Library Functions
1.1.1.InitLibrary
Format
Parameters
[in] License–Null terminated string that holds license key value.
Return
SLIB_ERR_SCANNER_BUSSY: The scanner is still busy executing the previous scanner command.
LICENSE_VALID: License is valid and the library is ready to be used.
LICENSE_INVALID: The license is invalid. All scanner operations are disabled.
LICENSE_EXPIRED: License has expired. All scanner operations are disabled.
SLIB_ERR_DRIVER_NOT_FOUND: The scanner driver was not found. To fix this error re-install
the scanner’s driver. All scanner operations are disabled.
SLIB_ERR_SCANNER_NOT_FOUND: The scanner is not connected to the PC. To fix this error
make sure the scanner is connected and re-starts the. All scanner operations are disabled.
Remarks
Use this function to initialize the scanner library. This function loads the scanner driver and initializes
the internal image structure. This function must be called before calling any other function in the
library.
IMPORTANT: When the application unload is should call the function UnInit to unload the
SDK and release its memory (See the function description as section 1.1.34 on ScanWex.pdf )

Library IdData: General Functionality
IdData library is where most of the image processing and data extraction is being handled. The library
fetches the internal image (the last scanned image), process its graphic information and activates the
OCR. The resultant text is kept in internal data structure ready to be retrievedby the application.
Notice: The library processes only the last image that was recently scanned. The library does not
support external image file processing.

If non of the above error values is returned, the function return the state id value.
Remarks
Use this function to automatically detect the state type according to the image. If the function returns
with non of the above error values then the return value is the state id. This value can be assigned to the
input parameter IdState in the function ProcStatefor data extraction.
