Table 8.5 Pseudo objects for resource retrieval; each pseudo object P in this table creates two arrays with resources P[ ]and pages[ ]/P[ ].object nameextgstatesfontsimagesexplanation(Array of dicts) Array containing the dictionaries for all extended graphics states (ExtGStates) on the pageor in the document(Array of dicts) Array containing dictionaries for all fonts on the page or in the document. In addition tothe standard PDF keys in font dictionaries, the following pseudo keys are supported:name (String) PDF name of the font without any subset prefix. Non-ASCII CJK font names will beconverted to Unicode.embedded (Boolean) Embedding status of the fonttype (String) Font typevertical (Boolean) true for fonts with vertical writing mode, false otherwise(Array of dicts) Array containing dictionaries for all images on the page or in the document. In additionto the standard PDF keys the following pseudo keys are supported:bpc (Integer) The number of bits per component. This entry is usually the same asBitsPerComponent, but unlike this it is guaranteed to be available.colorspaceid(Integer) Index of the image’s color space in the colorspaces[] pseudo object. This can beused to retrieve detailed color space properties.filterinfomaskidmaskonly(Dict) Describes the remaining filter for streams with unsupported filters or when retrievingstream data with the keepfilter option set to true. If there is no such filter no filterinfodictionary will be available. The dictionary contains the following entries:name (Name) Name of the filtersupported (Boolean) True if the filter is supporteddecodeparms(Dict) The DecodeParms dictionary if one is present for the filter(Integer) Index of the image’s mask in the images[] pseudo object if the image is masked,otherwise -1(Boolean) If true, the image is only used as a mask for (one or more) other images, but notdirectlypatternspropertiesshadingstemplates(Array of dicts) Array containing dictionaries for all patterns on the page or in the document(Array of dicts) Array containing dictionaries for all properties on the page or in the document(Array of dicts) Array containing dictionaries for all shadings on the page or in the document.

8.6 Encrypted PDF DocumentspCOS supports encrypted and unencrypted PDF documents as input. However, full objectretrieval for encrypted documents requires the appropriate master password to besupplied when opening the document. Depending on the availability of user and masterpassword, encrypted documents can be processed in one of the pCOS modes describedbelow.Full pCOS mode (mode 2). Encrypted PDFs can be processed without any restrictionprovided the master password has been supplied upon opening the file. All objects willbe returned unencrypted. Unencrypted documents will always be opened in full pCOSmode.Restricted pCOS mode (mode 1). If the document has been opened without the appropriatemaster password and does not require a user password (or the user password hasbeen supplied) pCOS operations are subject to the following restriction: The contents ofobjects with type string, stream, or fstream can not be retrieved with the following exceptions:> The objects /Root/Metadata and /Info/* (document info keys) can be retrieved ifnocopy=false or plainmetadata=true.> The objects bookmarks[...]/Title and annots[...]/Contents (bookmark and annotationcontents) can be retrieved if nocopy=false, i.e. if text extraction is allowed for themain text on the pages.Minimum pCOS mode (mode 0). Regardless of the encryption status and the availabilityof passwords, the universal pCOS pseudo objects listed in Table 8.3 are always available.For example, the encrypt pseudo object can be used to query a document’s encryptionstatus. Encrypted objects can not be retrieved in minimum pCOS mode.Table 8.6 lists the resulting pCOS modes for various password combinations. Dependingon the document’s encryption status and the password supplied when openingthe file, PDF object paths may be available in minimum, restricted, or full pCOSmode. Trying to retrieve a pCOS path which is inappropriate for the respective modewill raise an exception.Table 8.6 Resulting pCOS modes for various password combinationsIf you know...none of the passwordsonly the user passwordthe master password...pCOS will run in...restricted pCOS mode if no user password is set, minimum pCOS modeotherwiserestricted pCOS modefull pCOS mode8.6 Encrypted PDF Documents 193
