NAME

       jbig2enc - encoder for JBIG2

SYNOPSIS

       jbig2 [options] <input filenames...>

OPTIONS

       -b <basename>: output file root name when using symbol coding

       -d --duplicate-line-removal: use TPGD in generic region coder

       -p --pdf: produce PDF ready data

       -s --symbol-mode: use text region, not generic coder

       -t <threshold>: set classification threshold for symbol coder (def: 0.92)

       -w <weight>: set classification weight for symbol coder (def: 0.50)

       -T <bw threshold>: set 1 bpp threshold (def: 200)

       -G --global: use global BW threshold on 8 bpp images;

              the default is to use local (adaptive) thresholding

       -r --refine: use refinement (requires -s: lossless)

       -O <outfile>: dump thresholded image as PNG

       -2: upsample 2x before thresholding

       -4: upsample 4x before thresholding

       -S: remove images from mixed input and save separately

       -j --jpeg-output: write images from mixed input as JPEG

       -a --auto-thresh: use automatic thresholding in symbol encoder

       -D --dpi: force dpi

       --no-hash: disables use of hash function for automatic thresholding

       -V --version: version info

       -v: be verbose
