mkbitmap 1.16. Transforms images into bitmaps with scaling and filtering.
Usage: mkbitmap [options] [file...]
Options:
-h, --help - print this help message and exit
-v, --version - print version info and exit
-l, --license - print license info and exit
-o, --output <file> - output to file
-x, --nodefaults - turn off default options
Inversion:
-i, --invert - invert the input (undo 'blackboard' effect)
Highpass filtering:
-f, --filter <n> - apply highpass filter with radius n (default 4)
-n, --nofilter - no highpass filtering
-b, --blur <n> - apply lowpass filter with radius n (default: none)
Scaling:
-s, --scale <n> - scale by integer factor n (default 2)
-1, --linear - use linear interpolation
-3, --cubic - use cubic interpolation (default)
Thresholding:
-t, --threshold <n> - set threshold for bilevel conversion (default 0.45)
-g, --grey - no bilevel conversion, output a greymap
Possible input file formats are: pnm (pbm, pgm, ppm), bmp.
The default options are: -f 4 -s 2 -3 -t 0.45
