ReadConfigFile: Read a Tesseract Variable Configuration File

In duncantl/Rtesseract: Interface to the tesseract OCR system

Read a Tesseract Variable Configuration File

Description

This function finds and reads a tesseract configuration file that specifies one or more variable value pairs per line. This can be a convenient way to set multiple variables.

Usage

ReadConfigFile(api, files, debug = FALSE, ok = FALSE)

Arguments

api	an instance of the TesseractBaseAPI-class obtained from a call to tesseract
files	a character vector giving the names of one or more tesseract configuration files. These can be paths to the files or alternatively just the names of the files if they are located in directories that tesseract searches by default. These are the subdirectories configs/ and tessconfigs/ within tesseracts data path which can be queried with GetDatapath.
debug	if TRUE, then only process the debug parameter settings and not the regular ones.
ok	a logical value which controls whether to check if the files actually exist

Value

This is used for its side-effect of updating the tesseract instance with the variable values in the file.

Examples

ts = tesseract()
ReadConfigFile(ts, "bigram", ok = TRUE) # read from tessdata/configs

f = system.file("sampleConfigFile", package = "Rtesseract")
GetVariables(ts)["certainty_scale"]
GetVariables(ts)["debug_fix_space_level"]
ReadConfigFile(ts, f, debug = TRUE)
GetVariables(ts)["debug_fix_space_level"]
GetVariables(ts)["certainty_scale"] # unchanged
ReadConfigFile(ts, f)
GetVariables(ts)["certainty_scale"] # changed
