  --char_spacing  Inter-character space in ems  (type:double default:0)
  --underline_start_prob  Fraction of words to underline (value in [0,1])  (type:double default:0)
  --underline_continuation_prob  Fraction of words to underline (value in [0,1])  (type:double default:0)
  --min_coverage  If find_fonts==true, the minimum coverage the font has of the characters in the text file to include it, between 0 and 1.  (type:double default:1)
  --degrade_image  Degrade rendered image with speckle noise, dilation/erosion and rotation  (type:bool default:true)
  --rotate_image  Rotate the image in a random way.  (type:bool default:true)
  --distort_image  Degrade rendered image with noise, blur, invert.  (type:bool default:false)
  --invert  Invert the image  (type:bool default:true)
  --white_noise  Add  Gaussian Noise  (type:bool default:true)
  --smooth_noise  Smoothen Noise  (type:bool default:true)

  --find_fonts  Search for all fonts that can render the text  (type:bool default:false)
  --render_per_font  If find_fonts==true, render each font to its own image. Image filenames are of the form output_name.font_name.tif  (type:bool default:true)
  --list_available_fonts  List available fonts and quit.  (type:bool default:false)
  --render_ngrams  Put each space-separated entity from the input file into one bounding box. The ngrams in the input file will be randomly permuted before rendering (so that there is sufficient variety of characters on each line).  (type:bool default:false)
  --output_word_boxes  Output word bounding boxes instead of character boxes. This is used for Cube training, and implied by --render_ngrams.  (type:bool default:false)
  --bidirectional_rotation  Rotate the generated characters both ways.  (type:bool default:false)
  --only_extract_font_properties  Assumes that the input file contains a list of ngrams. Renders each ngram, extracts spacing properties and records them in output_base/[font_name].fontinfo file.  (type:bool default:false)
  --output_individual_glyph_images  If true also outputs individual character images  (type:bool default:false)

  --F  File listing font properties  (type:string default:font_properties)
  --X  File listing font xheights  (type:string default:)
  --U  File to load unicharset from  (type:string default:unicharset)
  --O  File to write unicharset to  (type:string default:)
  --output_trainer  File to write trainer to  (type:string default:)

  --font  Font description name to use  (type:string default:Arial)
  --unicharset_file  File with characters in the unicharset. If --render_ngrams is true and --unicharset_file is specified, ngrams with characters that are not in unicharset will be omitted  (type:string default:)
