Create a gocr Configuration

Usage

gocrConfig(
  inputfile,
  showhelp = FALSE,
  outputfile = "",
  errorfile = "",
  progressfile = "",
  databasepath = "",
  outputformat = "",
  greylevel = 0,
  dustsize = -1,
  spacewidth = 0,
  verbosity = 0,
  limitVerbosityToChars = "",
  limitRecognitionToChars = "",
  certainty = 95,
  mode = 0,
  onlyRecogniseNumbers = FALSE
)

Arguments

inputfile: -i file: read input from file (or stdin if file is a single dash)
showhelp: -h: show usage information
outputfile: -o file: send output to file instead of stdout. If "" (default), a file "gocrOut_<basename(outputfile)>" in tempdir() is used as the output file.
errorfile: -e file: send errors to file instead of stderr or to stdout if file is a dash
progressfile: -x file: progress output to file (file can be a file name, a fifo name or a file descriptor 1...255), this is useful for GUI developpers to show the OCR progress, the file descriptor argument is only available, if compiled with __USE_POSIX defined
databasepath: -p path: database path, that will be populated with images of learned characters. If "" (default), and a database is needed, a directory within the folder of the installed package is used
outputformat: -f format: output format of the recognized text (ISO8859_1 TeX HTML XML UTF8 ASCII), XML will also output position and probability data
greylevel: -l level set grey level to level (0<160<=255, default: 0 for autodetect), darker pixels belong to characters, brighter pixels are inter- preted as background of the input image
dustsize: -d size: set dust size in pixels (clusters smaller than this are removed), 0 means no clusters are removed, the default is -1 for auto detection
spacewidth: -s num: set spacewidth between words in units of dots (default: 0 for autodetect), wider widths are interpreted as word spaces, smaller as character spaces
verbosity: -v verbosity: be verbose to stderr; verbosity is a bitfield. Use optionValueVerbosity to get a proper value
limitVerbosityToChars: -c string: only verbose output of characters from string to stderr, more output is generated for all characters within the string, the
limitRecognitionToChars: -C string: only recognise characters from string, this is a filter function in cases where the interest is only to a part of the character alphabet
certainty: -a certainty: set value for certainty of recognition (0..100; default: 95), characters with a higher certainty are accepted, characters with a lower certainty are treated as unknown (not recognized); set higher values, if you want to have only more certain recognized characters
mode: -m mode: set oprational mode; mode is a bitfield (default: 0). Use optionValueMode to get a proper value
onlyRecogniseNumbers: -n bool: if bool is non-zero, only recognise numbers (this is now obsolete, use -C "0123456789")
