Properties
public Double MarginLeft { get; set; } #Left page margin in points used when inferring column bounds. Default: 36.
public Double MarginRight { get; set; } #Right page margin in points used when inferring column bounds. Default: 36.
public Double BinWidth { get; set; } #Histogram bin width (points) used for gutter detection. Default: 5.
public Double MinGutterWidth { get; set; } #Minimum detected gutter width (points) to consider a two-column layout. Default: 24.
public Double LineMergeToleranceEm { get; set; } #Maximum baseline-normal delta in font-size em units for ordinary line clustering. Default: 0.6. A stricter value disables conservative inline-script attachment.
public Double LineMergeMaxPoints { get; set; } #Maximum absolute baseline-normal delta for ordinary line clustering. Default: 2.5 points. With both merge limits at least their defaults, adjacent smaller-font scripts may attach to a unique base line; a stricter value retains baseline-only grouping.
public Boolean ForceSingleColumn { get; set; } #When true, forces single-column reading order and disables gutter detection. Default: false.
public PdfReadingDirection ReadingDirection { get; set; } #Horizontal reading direction used for words and column partitions. Default: Auto.
public Boolean JoinSoftHyphensAcrossLines { get; set; } #When true, removes an explicit soft hyphen before a line break. Visible hyphens are preserved because PDF layout and letter case cannot prove that they are discretionary. Default: false.
public Double IgnoreHeaderHeight { get; set; } #Height from top of page (points) to ignore as header when emitting text. Default: 0.
public Double GapSpaceThresholdEm { get; set; } #Threshold in em units to insert a space between adjacent spans on the same line. Default: 0.35.
public Double GapGlyphFactor { get; set; } #Threshold as a fraction of previous span's average glyph advance to insert a space. Default: 0.60.
