Testing Image Processing Profiles

Step by Step

1. Import the KTA Package: ImageTesting.zip
2. Login to the KTA Workspace, then go to ImageTesting.form
3. If you check the option to use Document Conversion, the default profile included in the package converts to a 300 DPI color tiff
4. If you want to test with a different Document Conversion profile:
   1. Open the KTA Designer and open the Business Rule named BR_ImageTesting
   2. In the activity named “Document Conversion” change it to use the profile of your choice and then release the business rule
5. If you check the option to use Image Processing, then choose the Scan/VRS profile from the dropdown box
6. The Advanced Options group isn't shown by default and these options generally should not be changed
7. Import a document using the web capture control on the right side (first icon on the toolbar)
8. Click the Process button to see the resulting image on the right and metadata on the left

Basic Options

Use Document Conversion – Choose whether document conversion will be used before image processing.  Document conversion profiles cannot be changed dynamically, so to change the profile, edit the DC activity directly in business rule BR_ImageTesting.  

Use Image Processing – Can be disabled if only testing the result of Document Conversion, or IQA on the unprocessed source image.

IP Profile – Choose any IP profile already configured on the system, or use the included “BlankEVRS” profile.  As it suggests, this profile has blank eVRS Settings, and the “eVRS Settings Only” option enabled.  Thus it is the most minimal possible configuration and is ideal for testing eVRS strings using with the “Override eVRS String” option.

Advanced Options

In most cases, advanced options do not need to be changed.

Override eVRS String – When this is checked, then the Replacement eVRS String will be used instead of any eVRS string defined in the profile.

Document to Process – By default a copy of the source document will be made for processing.  This is useful because the source document remains unchanged, and this allows for changing profiles or other options to keep testing the effects of different image processing against new copies of the same original source document.  The copies are made within the source document’s folder.  Change the option to Use Source Directly if the source document itself should be modified.  This can be useful if testing the effect of running image processing multiple times on the same document.

Log History – Enables Business Rule Logging for the BR doing the processing.  After processing completes, a link to the job properties of the business rule will be shown.

Compared to EvrsCheck

EvrsCheck is a desktop utility that that is included with KTA at [Install Source]\Utilities\EvrsCheck\EvrsCheck.exe.  It allows for testing a raw eVRS string against an image to see the before and after versions.  One benefit to EvrsCheck is that it does not use any licensing to test with.

Because ImageTesting.form is using true runtime processing, importing or making copies of documents does use actual Imaging Page Count volume.  Volume usage aside, testing this way has a number of benefits:

• Unlike only testing raw eVRS strings, this tests the result of the full set of settings configured in an Image Processing profile.
• Document Conversion can be used to start from a wider array of file formats
• IQA and eVRS metadata are displayed
• Processed images  can be saved to disk using the Repository Browser if needed.  EvrsCheck cannot save processed images.
