PDFlib Text Extraction Toolkit (TET) Manual

2 TET Command-Line Tool
2.1 Command-Line Options
The TET command-line tool allows you to extract text and images from one or more PDF
documents without the need for any programming. Output can be generated in plain
text (Unicode) format or in TETML, TET’s XML-based output format. The TET program
can be controlled via a number of command-line options. The program will insert space
characters (U+0020) after each word, U+000A after each line, and U+000C after each
page. It is called as follows for one or more input PDF files:
tet [] ...
The TET command-line tool is built on top of the TET library. You can supply library options
using the --docopt, --tetopt, --imageopt, and --pageopt options according to the option
list tables in Chapter 10, »TET Library API Reference«, page 121. Table 2.1 lists all TET
command-line options (this list will also be displayed if you run the TET program without
any options).
Note In order to extract CJK text you must configure access to the CMap files which are shipped with
TET according to Section 0.1, »Installing the Software«, page 7.
