Filtering text field vertical lines with IBM Datacap Taskmaster Capture

Filtering text field vertical lines

with Datacap Taskmaster Capture

Abstract

I have text fields on a form that have half boxes for each character in the field. How do I filter out the vertical lines so that the text can be read?

Cause

Some forms use half boxes for text fields, in which each box holds one character. Normal line removal can leave the vertical parts of the boxes, causing the field to be misread. Taskmaster Capture 8.0.1 Fix Pack 3 added a new image enhancement function called Comb Removal.

Answer

To add comb removal to image enhancement:

1. Navigate to the \Datacap\(application)\dco_(workflow) folder and make a copy of ImageFix.ini.


2. Edit ImageFix.ini and add the following:
   [CombRemoval]
   ON=True
   CombHeight=50
   CombSpacing=50
   HorizontalLineThick=4
   MinimumCombLength=50
   MinimumConfidence=50
   VerticalLineThick=4


3. Save the file and test.


4. Modify the values as needed to get the best results. All values are in pixels.

Note: Fix Pack 3 or newer is required.
