Select this option when you need to straighten documents that were scanned crookedly.
If the Acquire options you selected do not generate the results you were hoping for, you can change them
manually after scanning/opening your documents. See Section 7: Editing the Recognized Documents
to learn how to do so.
Font type and Character pitch
Font type
Readiris distinguishes between "regular" and dot matrix printed documents. Dot matrix printers are printers
that create documents with text made up of isolated, separate dots.
Special segmentation and recognition techniques are required to recognize dot matrix documents and need
to be activated.
To select the font type:
 Click the Readiris button, and then click Advanced Settings.
 Click the tab Font type.
 The font type is set to Automatic by default.
That way, Readiris recognizes "24 pin" or "NLQ" (Near Letter Quality) dot matrix, or other "normal"
printing.
 To recognize only dot matrix printed documents, click Dot matrix.
Readiris will recognize so-called "draft" or "9 pin" dot matrix printed documents.
Character pitch
The character pitch is the number of characters per inch in a particular font. The character pitch can either
be fixed, in which case all characters have the same width, or proportional, in which case the characters
have a different width.
To select the character pitch:
 Click the Readiris button, and then click Advanced Settings.
 Click the tab Font type.
 The character pitch is set to Automatic by default.
 Click Fixed if all characters of the font have the same width. This is often the case in old typewriter
documents.
 Click Proportional if the characters of the font have a different width. Virtually all fonts in
newspapers, magazines and books are proportional.
Important: these document characteristics do not apply to Asian, Hebrew or Arabic documents.
