Table 10.8 Document options for TET_open_document( ) and TET_open_document_callback( ) option password repair requiredmode shrug description (String) The user, master or attachment password for encrypted documents. If the document’s permission settings allow text copying then the user password is sufficient, otherwise the master password must be supplied. See the pCOS Path Reference to find out how to query a document’s encryption status, and pCOS operations which can be applied even without knowing the user or master password. The shrug option can be used to enable content extraction from protected documents under certain conditions (see Section 5.1, »Extracting Content from protected PDF«, page 59). (Keyword) Specifies how to treat damaged PDF documents. Repairing a document takes more time than normal parsing, but may allow processing of certain damaged PDFs. Note that some documents may be damaged beyond repair (default: auto): force Unconditionally try to repair the document, regardless of whether or not it has problems. auto Repair the document only if problems are detected while opening the PDF. none No attempt will be made at repairing the document. If there are problems in the PDF the function call will fail. (Keyword) The minimum pcosmode (minimum/restricted/full) which is acceptable when opening the document. The call will fail if the resulting pcosmode (see the pCOS Path Reference) would be lower than the required mode. If the call succeeds it is guaranteed that the resulting pcosmode is at least the one specified in this option. However, it may be higher; e.g. requiredmode=minimum for an unencrypted document will result in full mode. Default: full (Boolean) If true, the shrug feature will be activated to enable content extraction from protected documents under certain conditions (see Chapter 5.1, »Extracting Content from protected PDF«, page 59). By using the shrug option you assert that you will honor the PDF document author’s rights. Default: false tetml (Option list) TETML output will be initiated, and can be created page by page with TET_process_page( ). The following suboptions are supported: elements (List of Boolean) Specify whether certain TETML elements will be included in the output (default: all true): docinfo The /TET/Document/DocInfo element docxmp The /TET/Document/Metadata element options The elements /TET/Document/Options and /TET/Document/Pages/Page/Options encodingname (Keyword) The name to use in the XML encoding declaration of the text declaration of the generated TETML. The output will always be created in UTF-8 (default: UTF-8): _none No encoding declaration will be created; the output will still be in UTF-8 format. UTF-8 The declaration encoding="UTF-8" will be created. Any other encoding name will be used literally in the encoding declaration. The client is responsible for supplying a suitable encoding name and converting the generated TETML (which is UTF-8) to the specified encoding after TET finished TETML output. filename (String) The name of the TETML file. If no filename is supplied, output will be created in memory, and can be retrieved with TET_get_xml_data( ). If the function call fails (i.e. the PDF input document could not successfully be opened), no TETML output will be created. unknownchar (Unichar) Character to be used as a replacement for characters which cannot be mapped to Unicode because of inconsistent or missing information in the PDF document. U+0000 means that unknown characters will be removed. Default: U+FFFD (Replacement Character) Related options: use fold={{[:Private_Use:] unknownchar}} to also replace unknown (PUA) characters with the specified unknownchar, or fold={{[:Private_Use:] remove}} to remove them. 164 Chapter 10: TET Library API Reference
Table 10.8 Document options for TET_open_document( ) and TET_open_document_callback( ) option usehostfonts wordseparator description (Boolean) If true, data for fonts which are not embedded, but are required for determining Unicode mappings will be searched on the OS X or Windows host operating system. Default: true (Unichar; Only for granularity=line and page) Character to be inserted between words 2 . Default: U+0020 1. See footnote 2 in Table 10.9 2. Use U+0000 to disable the separator. 10.7 Document Functions 165
