The pktype program translates a packed font file (pk) (output by, for example, gftopk(1) to a file that humans can read. It also serves as a pk file-validating program (i.e., if pktype can read it, it's correct) and as an example of a pk-reading program for other software that wants to read pk files.
The input pk_file on the command line may omit the suffix `pk. The plain text translation is always written to standard output.
The output file gives a compact encoding of the packed encoding, using conventions described in the source code. Run lengths of black pixels alternate with parenthesized run lengths of white pixels, and brackets are used to indicate when a row should be repeated.
See tex(1) for the details of the searching.
