FontPitchMode

Determines how Grooper interprets the width of characters (font pitch) when reconstructing text from OCR results.

Remarks

'Font Pitch Mode' affects how Grooper inserts spaces and segments words during OCR synthesis, based on whether the text uses a fixed-pitch (monospaced) or variable-pitch (proportional) font.

• Auto: Grooper analyzes each segment to detect the most appropriate pitch mode, adapting to mixed or unknown fonts.
• Fixed: All characters are treated as having the same width, ideal for typewritten or monospaced documents.
• Variable: Character widths are allowed to vary, matching most modern printed or digital fonts.

Choosing the correct 'Font Pitch Mode' is important for accurate word segmentation, especially in documents with columns, tables, or inconsistent spacing.

Usage

• Use 'Auto' for most documents, especially when font type is unknown or varies within the document.
• Use 'Fixed' for legacy, typewritten, or monospaced text to improve segmentation accuracy.
• Use 'Variable' for documents known to use proportional fonts.

Best Practices

• Test different modes on your sample documents to determine which produces the best results.
• 'Auto' is generally recommended for flexibility and accuracy across diverse content.

Can be one of the following values:

Name	Value		Description
Auto	0	►	Grooper will automatically determine the font pitch for each segment of text. Use this option when documents may contain a mix of fixed-pitch and variable-pitch fonts, or when the font type is unknown. Grooper analyzes the spacing of characters to select the most appropriate pitch mode for each segment. Recommended for most use cases, especially when processing diverse or unpredictable documents.
Fixed	1	►	Grooper will treat all text as fixed-pitch (monospaced). Use this option when you know the document uses a fixed-pitch font throughout (such as typewritten forms or certain machine-printed reports). All characters are assumed to have the same width. Can improve segmentation accuracy and performance for monospaced documents.
Variable	2	►	Grooper will treat all text as variable-pitch (proportional). Use this option when you know the document uses a variable-pitch font throughout (such as most modern printed or digital documents). Character widths are allowed to vary. Recommended for documents with proportional fonts or mixed content where fixed-pitch is not appropriate.
