PDF recompressor that uses jbig2enc encoder with improved perceptually lossless coding for symbol coding. These images are re-compressed by modified jbig2enc with use of symbol coding.

Usage: -pathToEnc <Path to jbig2enc> -input <pdf file> [OPTIONAL]

Mandatory options:
-pathToEnc <Path to jbig2enc>: path to trigger of jbig2enc (usually file named jbig2)
-intput <pdf file>: pdf file that should be recompressed

OPTIONAL parameters:
-output <outputPdf>: name of output pdf file (if not given used input pdf file
-passwd <password>: password used for decrypting file
-thresh <valueOfDefaultThresholding>: value that is set to enkoder with switch -t
-autoThresh: engage automatic thresholding (special comparing between two symbols to make better compression ratio)
-pages <list of page numbers> -pagesEnd: list of pages that should be recompressed (taken only pages that exists, other ignored) -- now it is not working
-binarize: enables to process not bi-tonal images (normally only bi-tonal images are processed and other are skipped)
-q: silent mode -- no error output is printed
