See the Standard OCR Tool Parameters section for details.
Use Default Font: Select whether to use pre-trained fonts. Uncheck to use only user-trained fonts.
Font: Select the font to use.
Confidence: Allow you to specify the minimum level of character identification confidence required before a character will be read and output. (Range: 0.0 to 1.0)
Auto Size: Allow you to specify the width and height of a character (in pixels) or use Auto Size. Disable Auto Size for more reliable reading.
Width: Specify the character width (in pixels) when Auto Size is disabled. (Range: 10-200)
Height: Specify the character height (in pixels) when Auto Size is disabled. (Range: 10-200)
Connection Strength: Help correct for characters that are either touching or are formed by individual dots such as those produced by a dot peen stylus or inkjet printing.
This parameter ranges from -3 (AutoVISION will search for characters that are underprinted or not touching) to 3 (AutoVISION will search for characters that are overprinted or touching).
When set to 0, AutoVISION does not perform any pre-processing (multiple passes of an "erode" function for -3, -2, and -1 or multiple passes of a "dilate" function for 1, 2, and 3), so processing time will be decreased.
Unknown Character: Allow you to set the character that will be returned from the font reading process when no match can be made within the selected font. The default character is ?. For example, if the tool cannot decipher the 'H' in "MICROHAWK", the output string will be MICRO?AWK.
Multiline Separator: If the string has multiple lines, the Multiline Separator will be inserted into the string between lines.
Match String Enable: Select whether to perform string matching.
Match String: Allow you to specify the string that must be matched for the OCR Tool to pass. See the OCR Tool Match String for details. (up to 254 strings)
Min Character Area (Pixels) is displayed only when you disable the Allow Segmented Characters option. This setting specifies the minimum size of a character, thereby eliminating segments that are too small to be characters by themselves. The default setting is 40 pixels.
Use Wildcard ? in Match String: Select whether to use Wildcards "?" in string matching.
Auto Teach Options: Learn Match String.
