Table 2.1 TET command-line options option parameters function --imageloop page | resource Specifies the kind of enumeration loop for extracting images with the --image option (default: resource if --tetml is specified, otherwise page): page resource Enumerate all images on the selected pages. Images which are placed multiply will be extracted multiply. Extracted images will be named according to the following pattern: _p_.[tif|jpg|jpx|jbig2] Enumerate all (merged) image resources in the document. Each image resource will be extracted only once, regardless of the number of occurrences in the document. The --firstpage and --lastpage options will be ignored for extracting images. Extracted images will be named according to the following pattern: _I.[tif|jpg|jpx|jbig2] Note: I is also used in the TETML attribute Image/@id. --imageopt Additional option list for TET_write_image_file( ) (see Table 10.17, page 183) --lastpage -l --outfile -o --pagecount | last The number of the page where content extraction will finish. The keyword last specifies the last page, last-1 the page before the last page, etc. Default: last (Not allowed if multiple input file names are supplied) File name for text or TETML output. The file name »-« can be used to designate standard output provided only a single input file has been supplied. Default: name of the input file, with .pdf or .PDF replaced with .txt (for text output) or .tetml (for TETML output). Print the number of pages in the document, i.e. the value of the pCOS path length:pages, to stdout or the file provided with --outfile. --pageopt Additional option list which will be supplied to TET_open_page( ) if text output is generated, or to TET_process_page( ) if TETML output is generated. See Table 10.10, page 169 and Table 10.18, page 185, for a list of available options. For text output the option granularity will always be set to page. --password, -p --samedir --searchpath 1 -s --targetdir -t --tetml -m ... glyph | word | wordplus | line | page User, master or attachment password for encrypted documents. In some situations the shrug feature can be used to index protected documents without supplying a password (see Section 5.1, »Extracting Content from protected PDF«, page 59). Create output files in the same directory as the input file(s). Name of one or more directories where files (e.g. CMaps) will be searched. Default: installation-specific Output directory for generated text, TETML, and image files. The directory must exist. This option is ignored if --samedir is specified. Default: . (i.e. the current working directory) (Can not be combined with --text) Create TETML output according to the TET 3 schema containing text and image information. TETML will always be created in UTF-8. The supplied parameter selects one of several variants (see Section 9.2, »Controlling TETML Details«, page 127): glyph Glyph-based TETML with glyph geometry and font details word Word-based TETML with word boxes wordplus Word-based TETML with word boxes plus all glyph details line Line-based TETML (text only) page Page-based TETML (text only) --tetopt Additional option list for TET_set_option( ) (see Table 10.2, page 148). The option outputformat will be ignored (use --format instead). 18 Chapter 2: TET Command-Line Tool
