Test 1:
Choose
Initialize
and then
Module Information
in the Engine menu.
The initialization test confirms that installation and license activation were successful and also that the
recognition engine (ENGine) is ready for use on your machine. The module information test lets you check
that all licensed modules are really available.
If initialization fails, view the panel
Show Licenses
in the License Manager, to be sure a suitable license is
valid. You should delete any licenses that are no longer in use (for previous versions or expired evaluation
versions) since these may block current licenses.
If initialization fails but licenses are in order, there may be missing or damaged program files. Be sure your
computer is virus-free. Uninstalling and re-installing the SDK may solve the problem. You should be able to
do this without having to work through the licensing procedure again.
Test 2:
Choose
Recognition
in the Test menu.
This takes a sample image file and recognizes it, sending output to TEST1.TXT.
Recognition may fail if the sample image file has been moved, deleted, modified or replaced with a different
file. Be sure the dimensions and size of the input file lie within the capabilities of the ENGine, and that it
does contain imaged text of sufficient quality for OCR to be successful. Please consult the Module
Specification topics in the documentation to find these limitations, in particular the IMG Image Manage-
ment module and the recognition modules you intend to use.
Deciding the interface
For evaluation purposes the IPRO interface is recommended, maybe used together with the Visual Toolbox
controls. For your development work both interfaces yield the same recognition accuracy. Other criteria to
consider are:
• The RECapi traditional C/C++ interface is best suited to high throughput single page processing tasks and for
applications where processing time needs to be minimized.
• The IPRO ActiveX interface is recommended when document-level processing is needed, and where access to
visual controls is desirable.
Running the Sample Viewer Application
A sample viewer application is provided for each interface. These are designed to demonstrate the
functionalities of the toolkit through 40 working samples. We recommend you run samples 1-14, to test
basic functionality. In addition you may want to run further samples – those relevant to your configuration
and development plans.
The Sample Viewers can be launched from the Windows Start Menu, under
ScanSoft OmniPage Capture SDK.
Please choose the viewer of the interface you plan to use for your development.
• RECapi Sample Viewer App - C
• IPRO Sample Viewer App - C++
• IPRO Sample Viewer App - VB
The Sample Viewer window displays the following areas:
•
Description window:
summarizes the purpose of the current sample.
•
Console window:
displays status messages as the samples run to denote progress and to report any problems
encountered.
