PDFlib Text Extraction Toolkit (TET) Manual

You can specify the amount of text in the smallest element with the granularity option
of TET_process_page( ).
> For granularity=glyph or word you can additionally specify the amount of glyph details.
Using the geometry and font suboptions you can omit some parts of the glyph
information if you don’t need it.
The following page option list generates TETML output in wordplus mode with all glyph
details:
granularity=word glyphdetails={geometry=true font=true}
Table 8.2 summarizes the options for creating page modes.

Document options for controlling TETML output. In this section we will summarize
the effect of various options which directly control the generated TETML output. All
other document options can be used to control processing details. The complete description
of document options can be found in Table 10.3.
Document-related options must be supplied to the --docopt command-line option or
to the TET_open_document( ) function.
The tetml option controls general aspects of TETML. The elements suboption can be
used to suppress certain TETML elements if they are not required. The following document
option list will suppress document-level XMP metadata in the generated TETML
output:
tetml={ elements={nodocxmp} }
The engines option enables or disables the text and image extraction engines. The following
option list will process text contents, but disable image processing:
engines={noimage}
All document options which have been supplied when creating TETML will be recorded
in the /TET/Document/Options element unless disabled with the following document option:
tetml={ elements={nooptions} }
Page options for controlling TETML output. The complete description of page options
can be found in Table 10.5. Page-related options must be supplied to the --pageopt command-line
option or to the TET_process_page( ) function.
