There are two Display Mode options � Strings and Chars.

Unless you are doing font training, you should always set Display Mode to Strings before you convert text.

 

Strings

When Display Mode is set to Strings, Scan2CAD displays text as strings, i.e. the characters are joined together as words and sentences.

 

When you convert text with Display Mode set to Strings:

Scan2CAD recognizes each character on the raster image and then joins the characters together into strings.
After Scan2CAD has recognized the text you can view it temporarily in Chars Display Mode by pressing ? on the keyboard. ? toggles between the Strings and Chars Display Modes.

 

Chars

When Display Mode is set to Chars, Scan2CAD displays text as individual characters that are not joined together into words and sentences. When Display Mode is set to Chars:

Numbers are displayed in green, upper-case letters in blue, lower-case letters in magenta and symbols in black.
A number appears under each character. This number is the character’s certainty percentage. For example if the character is an A, and the number under the character is 97, then Scan2CAD is 97% certain that the character is an A and not some other letter or number.

 

When you convert text with Display Mode set to Chars:

Scan2CAD recognizes each character on the raster image as an individual character.
It recognizes everything on the image that could possibly be text as a character. For example it might recognize a short line as a hyphen or as an “I”. This is because much of Scan2CAD’s “intelligent” text processing takes place when it creates text strings.
After Scan2CAD has recognized the text you can join the individual characters together into strings by selecting OCR Menu > Build Strings. When you do this, Scan2CAD discards many of the characters it recognized initially. Of the remaining characters, it converts those that have a certainty percentage less than the OCR Recognition Limit to question marks (?).
You must use OCR Menu > Build Strings to join the characters into strings before saving a vector file or saving text as an ASCII file.

 

Set Display Mode

Set Display Mode in the OCR Settings dialog, which appears when you select OCR Menu > Settings.
