Class OutputProfile.Feature

  • Enclosing class:
    OutputProfile
    public static class OutputProfile.Feature
extends java.lang.Object

    An OutputProfile is made up of Features, which may be required or denied. This class defines the available features. Broadly speaking they break down into two categories, those that can be easily determined, and those that require scanning the PDF to see if they apply.

    Those in the first category are returned by the PDF.getBasicOutputProfile() method, and are kept up to date as the PDF is updated. Those in the second category are only available via the PDF.getFullOutputProfile() method, which requires the PDF to be scanned to determine.

    An OutputProfile may be customized by setting these features as Required or Denied. See that class for more information.

        public static final OutputProfile.Feature HasAuthor
        The PDF Info dictionary has an Author set

      • HasSubject

        public static final OutputProfile.Feature HasSubject
        The PDF Info dictionary has a Subject set

      • HasProducer

      • HasModDate

        public static final OutputProfile.Feature HasModDate
        The PDF Info dictionary has a Modification Date set. When a PDF is written with the PDF library a modification date is always applied, but some documents read in may be missing one.

      • HasTrapped

        public static final OutputProfile.Feature HasTrapped
        The PDF Info dictionary has a Trapped key. PDF/X requires this to be set to "true" or "false - "unknown" is not allowed

      • Linearized

        public static final OutputProfile.Feature Linearized
        The PDF is Linearized (also known as web ready). Linearized PDFs may be read by the library, and setting this feature to "required" will cause them to be written as well.

      • LinearizedLoader

        public static final OutputProfile.Feature LinearizedLoader
        The PDF is Linearized and has been loaded using the Linearized Loader. This implies the PDF may still be loading.
        Since:
        2.14

      • MultipleRevisions

        public static final OutputProfile.Feature MultipleRevisions

        The PDF has multiple revisions. Typically this applies only to documents that have been digitally signed and then amended.

        Setting this feature to "required" will cause the document to be rendered with revisions, even if they are not required by the Document structure. Although rendering with revisions does increase the size of the document marginally, it does mean that the PDF file will only be appended to - any existing objects in the PDF will remain in the same file position. The only time this really matters is when a PDF has been read in using the PDFReader(File) constructor, and you want to write back to the same file. In this case the PDF file is used as a buffer, which means if your code looks like this... 

         File file = new File("file.pdf");
 PDF pdf = new PDF(new PDFReader(file));
 File tempfile = new File("temp.pdf");
 OutputStream out = new FileOutputStream(tempfile);
 pdf.render(out);
 out.close();
 tempfile.renameTo(file);
        ... you need to use this approach. You should always use a temporary file if you're doing this - writing to the same file you're reading from is not guaranteed to work, even with this setting.
        Since:
        2.0, with the ability to set this feature as "required" added in 2.11.2

      • UncompressedXRef

        public static final OutputProfile.Feature UncompressedXRef
        The PDF has the regular old-style XRef table. This is required to load the document in Acrobat prior to Acrobat 6.0, and it may be stored alongside a Compressed XRef for compatibility.

      • XRefGaps

        public static final OutputProfile.Feature XRefGaps
        The PDF has gaps in it's XRef table. Gaps are disallowed in the specification, but don't cause a problem for most PDF consumers. However if this feature is set it indicates the PDF may fail to load in some workflows.
        Since:
        2.24.1

      • CompressedXRef

        public static final OutputProfile.Feature CompressedXRef
        The PDF has a Compressed XRef table. These were added in Acrobat 6.0 and can drastically reduce the size of the file, unless they are used alongside the Normal XRef table (in which case they actually increase the file size). The PDF library can read both and will write on or the other, but currently not both, so settting this feature means the PDF will not load prior to Acrobat 6.0

      • Bookmarks

        public static final OutputProfile.Feature Bookmarks
        The PDF has a Bookmarks tree, as returned by PDF.getBookmarks(). If this feature is denied when an OutputProfile is applied, then the Bookmarks will be removed.

      • Thumbnails

        public static final OutputProfile.Feature Thumbnails
        The PDF has Thumbnails included with the document. This can make the PDF bigger then necessary, as these can be easily generated on the fly.
        Since:
        2.11.8

      • PageLabels

        public static final OutputProfile.Feature PageLabels
        The PDF has page labels. If this feature is denied when an OutputProfile is applied, then the labels will be removed.
        Since:
        2.10.3

      • Articles

        public static final OutputProfile.Feature Articles
        The PDF contains "Articles" (sometimes known as Threads). If this feature is denied when an OutputProfile is applied, then all Articles will be removed from the PDF. Note articles cannot be added or edited with this API.
        Since:
        2.7.1

      • StructureTreeEmpty

        public static final OutputProfile.Feature StructureTreeEmpty

        2.26

      • LanguageSpecified

        public static final OutputProfile.Feature LanguageSpecified
        The PDF has a valid Language tag, indicating the natural language of the document

      • LanguageInvalid

        public static final OutputProfile.Feature LanguageInvalid
        The PDF has an invalid Language tag, either on the catalog or in the Structure Tree. Invalid (as opposed to missing) tags are always invalid in PDF/A
        Since:
        2.26

      • EmptyLanguageSpecified

        public static final OutputProfile.Feature EmptyLanguageSpecified
        The PDF has a Language tag which is empty, indicating the language is specified to be unknown. This is distinct from a missing language tag, which means the language is unspecified.
        Since:
        2.24.2

      • TaggedTextLanguageUnspecified

        public static final OutputProfile.Feature TaggedTextLanguageUnspecified
        The PDF contains text reachable from the Structure Tree which has no language set. This is not allowed in PDF/UA-1 (not part of basic profile)
        Since:
        2.28.2

      • ReaderExtensions

        public static final OutputProfile.Feature ReaderExtensions
        The PDF contains Reader Extensions. These are added by LiveCycle or Acrobat to grant additional rights on the PDF in Acrobat Reader, such as the ability to complete forms. Modifying a Reader-extension enabled PDF can be done with the PDF library, but care must be taken not to invalidate the document during this process. Typically you should not alter the PDF in any way other than by setting the value of form fields or signing signature fields. If this feature is denied, the Reader Extensions will be removed and the document can be edited as normal.

      • XMPMetaData

        public static final OutputProfile.Feature XMPMetaData
        The PDF has XMP Metadata on the Document. XMP Metadata is added by default whenever a PDF is written, unless this feature is specifically denied.

      • XMPMetaDataPretty

        public static final OutputProfile.Feature XMPMetaDataPretty
        If this feature is set to "required" when rendering, it will cause any XMP output to be pretty-printed with indents, for easies visual inspection. It simply calls pdf.getXMP().set("indent", 1)
        Since:
        2.25

      • XMPMetaDataWrapper

        public static final OutputProfile.Feature XMPMetaDataWrapper
        If this feature is set to "required" when rendering, it will cause any XMP output to be wrapped in the optional <xmpmeta> element, to quieten warnings from toolchains that mistakenly think this is required. It simply calls pdf.getXMP().set("use-xmpmeta", 1)
        Since:
        2.28.4

      • BadXMPMetaData

        public static final OutputProfile.Feature BadXMPMetaData
        The PDF contains XMPMetadata that is structurally invalid. Since 2.20.1 this feature has been split, with the stricter tests require by PDF/A covered under XMPMetaDataTypeMismatch This is not allowed in PDF/A
        Since:
        2.6.7

      • XMPMetaDataIsFiltered

        public static final OutputProfile.Feature XMPMetaDataIsFiltered
        The PDF contains XMPMetadata that is encoded using a filter. This is not allowed in PDF/A (not part of basic profile).

        public static final OutputProfile.Feature XMPMetaDataInfoMismatchTrailingZero
        The PDF contains entries in its information dictionary that do not match exactly the corresponding entries in its XMP metadata - the values in the Information dictionary have a single additional trailing NUL byte. This is arguably not allowed in PDF/A, but Acrobat (amongst others) seems to allow it, so we distinguish this feature to allow results to match Acrobat. (not part of basic profile).
        Since:
        2.17

      • XMPMetaDataDescribesMultipleResources

        public static final OutputProfile.Feature XMPMetaDataDescribesMultipleResources
        The PDF contains XMP metadata containing RDF resource descriptors for multiple objects. This is invalid in RDF and so will invalidate the XMP metadata.
        Since:
        2.14

      • XMPMetaDataHasMixedResourceDescriptors

        public static final OutputProfile.Feature XMPMetaDataHasMixedResourceDescriptors
        The PDF contains XMP metadata containing RDF resource descriptors which are a mix of the empty string and the non-empty string. This is not allowed in XMP but was common practice in earlier revisions of a lot of software, including our own API and Acrobat.

        Opinion

        The XMP specification recommends this is tolerated so we allow it for PDF/A, but can be set as invalid to match the behaviour of some other toolkits. Acrobat 9, X and XI all disallow it in PDF/A-1 and later. The BFO API will always create files that don't set this feature (i.e. that meet the stricter definition of this rule), but be aware that calling PDF.setMetaData(java.lang.String) with your own custom XMP metadata will allow you to bypass this test. If you want to be sure when you do this, set the feature as denied on your OutputProfile, eg: 
         PDF pdf = new PDF();
 OutputProfile profile = new OutputProfile(OutputProfile.PDFA1b_2005, ...);
 profile.setDenied(OutputProfile.Feature.XMPMetaDataHasMixedResourceDescriptors);
 pdf.setOutputProfile(profile);
 pdf.setMetaData(yourdata);
        Since:
        2.14

      • XMPMetaDataXpacketFormatError

        public static final OutputProfile.Feature XMPMetaDataXpacketFormatError
        The PDF contains a malformed xpacket header in its XMP metadata. This is not allowed in PDF/A (not part of basic profile).
        Since:
        2.11.5

      • XMPMetaDataXpacketDeprecatedAttributes

        public static final OutputProfile.Feature XMPMetaDataXpacketDeprecatedAttributes
        The PDF contains XMP metadata which makes use of the deprecated attributes "bytes" or "encoding" in the xpacket header. This is not allowed in PDF/A (not part of basic profile).

      • XMPMetaDataXpacketUnknownAttributes

        public static final OutputProfile.Feature XMPMetaDataXpacketUnknownAttributes
        The PDF contains XMP metadata with an xpacket that contains unknown attributes. This is not allowed in PDF/A (not part of basic profile).

      • XMPMetaDataXpacketBeginError

        public static final OutputProfile.Feature XMPMetaDataXpacketBeginError
        The PDF contains XMP metadata where the begin attribute in the opening xpacket has an incorrect value. This is disallowed in XMP since the first edition, but no-one has ever verified it. (not part of basic profile)
        Since:
        2.24.3

      • XMPMetaDataXpacketMissing

        public static final OutputProfile.Feature XMPMetaDataXpacketMissing
        The PDF contains XMP metadata that is not wrapped in a pair of "xpacket" processing instructions. This is disallowed in XMP up to 2008, but allowed from 2012. (not part of basic profile)
        Since:
        2.24.4

      • XMPMetaDataXpacketDuplicated

        public static final OutputProfile.Feature XMPMetaDataXpacketDuplicated
        The PDF contains XMP metadata that is wrapped in multiple "xpacket" processing instructions. This is certainly incorrect, but we don't believe it's technically invalid: the outer-most xpacket is not the one wrapping the XMP metadata, so is excluded from the test. This argument could be made either way so the feature is distinct from the other Xpacket tests. It is currently not tested for as part of the PDF/A profiles. (not part of basic profile)
        Since:
        2.25

      • XMPMetaDataMissing

        public static final OutputProfile.Feature XMPMetaDataMissing
        The PDF contains XMP metadata which declares a property that is not defined in either the XMP specification or an internal PDF/A extension. This is invalid in PDF/A-1, A-2 and A-3, but relatively common otherwise, particularly for documents created by other Adobe tools which often make their own presumptions about which XMP properties are standard.

        public static final OutputProfile.Feature XMPMetaDataTypeMismatch
        The PDF contains XMP metadata which declares a property of a type that doesn't match the definition in the XMP specification or an internal PDF/A extension. This is invalid in PDF/A, and (if you care about valid XMP) slightly more serious than the similar feature XMPMetaDataMissing, as a standard property is being used incorrectly, although it is still relatively common. This feature also covers complex types that are missing a required field, for example if a "Dimension" object was missing its stDim:unit. (not part of basic profile)

        The PDF contains XMP metadata which declares a structured property value that contains a field which is not defined.

        Although it's not valid in PDF/A, prior to release 2.26 we allowed this due to a misinterpretation of "technical note 10". (not part of basic profile)

        The PDF contains a push-button annotation with an N entry that is a Stream. This is allowed in PDF/A-1, not allowed in PDF/A-2 or 3, but is normal in PDF. (not part of basic profile).

        Opinion

        Pushbuttons and Radio-buttons are implemented with the same object in PDF, but constructed in a slightly different manner. PDF/A-1 placed restrictions on how these were constructed that was intended to mirror best practice for how push-buttons were created, but which also caught radio-buttons in the same definition. Consequently it was impossible to create a functioning radio button in the original revision of PDF/A-1.

        This was revised for PDF/A-1 in TN0010 (and unchanged for PDF/A-2 and later), but unfortunately the reverse happened: the two were not distinguished, and the spec now required pushbuttons to be constructed like radio-buttons. Unlike the original requirement it's technically possible to do this, and the resulting PDF can be displayed in Acrobat and our viewer, but it's very non-standard and may not work everywhere.

        Acrobat XI will enforce the specification exactly as written, and documents with standard push-button fields are marked as invalid. Attempting to "fix" this in Acrobat will delete the button completely, although as a button in PDF/A is not allowed to have any actions associated with it this is arguably a sensible course of action.

        We will also enforce the specification in this way for PDF/A-1 and later, even though it's nonsensical. So when creating a PDF with a form for archiving PDFs you have three options:
        1. Normal best practice: Push buttons have a stream, radio buttons have a dictionary, so PushButtonAppearanceIsStream and RadioButtonAppearanceIsDictionary are set.
        2. PDF/A-1, 2 and 3: RadioButtonAppearanceIsDictionary is OK but PushButtonAppearanceIsStream is disallowed. Push buttons are possible but must be created in a non-standard manner.
        We don't repair these features by default, but you do have this option by setting the RadioButtonAppearanceIsDictionary feature feature to required on the profile. This will attempt to convert the structures into a form that is acceptable to PDF/A, although the document may not render correctly. A better option is always to delete the field, but this cannot be done automatically.

        The PDF contains a page or canvas with two Separations (either on their own, or as part of the N-Channel Colorants list) that give different results. This is not allowed in PDF/X-4 and later, or PDF/A-4. Note while PDF/X-4 says they "should produce similar appearance", PDF/A-4 says they "shall have the same tintTransform and alternateSpace." We're using the tighter definition for PDF/X as well.

        Also note that one way for this test to fail is if the Separation is based on a DeviceCMYK profile and used on two different pages, each of which has a different "DefaultCMYK" profile set.

      • RedefinedSeparationAllNone

        public static final OutputProfile.Feature RedefinedSeparationAllNone

        The PDF contains a page or canvas with two Separations called "All" or "None" (either on their own, or as part of the N-Channel Colorants list) that give different results. According to ISO32000 these two special Separations do not use the tintTransform and alternateSpace, but PDF/X-4 and PDF/A-2 and later do not make this exclusion, and for consistency the committee decided not to remedy this. So this feature exists and is denied in PDF/A-2 and X-4 and later.

        If denied, the repair process is slightly different to RedefinedSeparation in that the repair will always succeed - because by definition the tintTransform is ignored, it is simply set to anything.

There are only about twelve of these known, the main ones being MingLiu (and variations such as HA_MingLiU and PMingLiU) from 1995 and 1996 and DFKai-SB from 1998, both traditional Chinese fonts created by Dynalab, HuaTianKaiTi and HuaTianSongTi (simplified Chinese fonts by Huatian Information Industry) and some NEC Japanese fonts. Because our OpenType font parser does not use the hinting program we are unable to parse these fonts correctly, so even though they are embedded we will search the OS for a matching font, and when found will let the AWT render it - typically this will hand off to a native library which does parse the hinting program. Versions of our API prior to 2.16 did not handle these as well, and documents embedding these fonts may not have rendered correctly.

      • ImagePluginHeader

        public static final OutputProfile.Feature ImagePluginHeader
        The PDF should be marked as "image only". This feature may be set as required, in which case if the image contains only a full-page image then Acrobat 6.0 and later will display various options which allow treating the image as a photo for printing.

      • RegularCompression

        public static final OutputProfile.Feature RegularCompression
        The PDF should be compressed. This feature is normally off, which means that new streams are compressed in the usual manner but existing streams are left untouched. This is typically the best setting. Setting this feature as Required means that all streams compressed with less-than-optimal compression will be recompressed, which may take longer but result in smaller files (depending on how compressed the original file was). On the other hand, setting this feature as Denied will cause all existing compressed streams to be uncompressed, which is useful for debugging PDFs but gives much larger files.

      • DoubleCompression

        public static final OutputProfile.Feature DoubleCompression
        The PDF contains at least one stream which has to forms of compression applied, e.g. both Flate and DCT compression. This particular combination can trigger a bug in Acrobat where the white in the document goes bright-pink. While attractive, this is not generally desired. Denying this feature will remove the double compression and avoid this bug.
        Since:
        2.24.2

      • MaximumCompression

        public static final OutputProfile.Feature MaximumCompression
        The PDF should be compressed using the maximum level of compression. This feature affects the parameters to the "Flate" compression stream, and setting it causes the Deflater.BEST_COMPRESSION setting to be used. This can slow things down a fair bit so is off by default. Setting it typically works best when recompressing a file using the RegularCompression feature as well.
        Since:
        2.7.8

      • MergeResources

        public static final OutputProfile.Feature MergeResources
        When merging multiple PDFs, if this feature is set then the PDF will be scanned on render and duplicate resources (such as fonts and images) merged if possible. This process may be time consuming but can reduce the size of the resulting PDF. Performing this action on a signed PDF will almost certainly invalidate the signature. Here's an example: 
         PDF pdf1 = new PDF(new PDFReader(new File("file1.pdf")));
 pdf1.getOutputProfile().setRequired(OutputProfile.Feature.MergeResources);
 PDF pdf2 = new PDF(new PDFReader(new File("file2.pdf")));
 pdf1.getPages().addAll(pdf2.getPages());
 pdf1.render(new FileOutputStream("out.pdf"));
        As a result of this feature being set on "pdf1", when it's rendered it will be scanned looking for duplicate objects. If both PDFs embedded the same image, for example, these will be consolidated down to a single bitmap.
        Since:
        2.10.4
        See Also:
        MergeResourcesFast

      • MergeResourcesFast

        public static final OutputProfile.Feature MergeResourcesFast
        As for MergeResources, but skips most of the work and just picks off the items that are literally identical. This can have a big impact quite quickly for file that have been joined together from lots of smaller parts that contain identical information, for example colorspaces or images. However it will not be as effectice as the full, slower merge run with MergeResources is set.
        Since:
        2.19

      • PurgeResources

        public static final OutputProfile.Feature PurgeResources

        When saving a modified PDF, in general the PDF API will not include items that have been removed from the document. This feature can be set as "required" on a profile passed in to OutputProfiler#setProfile to force a rebuild of each content stream in the PDF - any unreferenced objects will be removed as part of that rebuild process.

        The actions described in the previous paragraph were added in version 2.28. Between versions 2.11.17 and 2.23 this feature could be set as "required" to remove unreferenced objects from the PDF when the file was saved, but from 2.23.1 on this happens automatically, so the feature became a no-op and was deprecated. Due to the new functionality we've undeprecated it in 2.28

        Since:
        2.11.17, but see not above

        public static final OutputProfile.Feature FileIsDamaged

      • RealOverflow

        public static final OutputProfile.Feature RealOverflow
        The PDF contains a real number > ±3.4028234 × 1038, which is the maximum size for a 32-bit float under IEEE754. This is not recommended in PDF but technically allowed in the PDF/A-2 specification, although it's unlikely to be correctly handled by most PDF readers. (not part of basic profile)

        Opinion

        The PDF specification recommends real numbers are "±3.403 x 1038 (approx)" but the PDF/A-2 and later specifications remove the "approx" from the text, so it's possible to create a number which fails this test but is still valid PDF/A. This is unlikely to be the intention of the specification, as numbers this large can only be represented by 64-bit doubles while Acrobat (and many other tools, including this one) use 32-bit floats internally. Consequently the chances of the the document being reliably reproducable are slim, and indeed Acrobat 9, X and XI will fail to display a PDF containing numbers like this.

        So while the specification only requires that we test for numbers that fail the less-demanding test RealOverflowPDFA, we recommend the condition defined by this feature to be met for any PDF/A documents, to ensure the document has a better chance of being reliably loaded on other environments.

      • OverprintOff

        public static final OutputProfile.Feature OverprintOff

        The PDF sets the Overprint flag to off. Although this value is the default if none is set, explicitiy setting it to off means that this PDF cannot safely be composited over another PDF that uses Overprint without potentially knocking out some of the background. Setting this feature to "denied" before applying an OutputProfile will ensure that explicit "overprint=off" operations are removed without affecting the rendering.

        It does this by converting all non-separation colors to DeviceCMYK, and by ensuring that any separations are tracked. Graphics operations with overprint off are converted to overprint on, and modified to ensure they knock out any previously seen separations. The effect should be identical, but the resulting file is safe to overprint over any separation not seen in this file.

        public static final OutputProfile.Feature StructureTreeParentTreeMismatch
        The StructureTree references some marked content nodes in the "ParentTree" list which are not accessible from the root of the tree. Effectively these nodes are "orphaned", but as they're not reachable from the root of the structure tree they're ignored by many PDF/UA tools. We don't consider these invalid, but do warn about them as it indicates the PDF may be larger than it needs to be. (not part of basic profile)

        public static final OutputProfile.Feature StructureTreeByIdMismatch
        The StructureTree "IDTree" map should serve as a lookup for each item in the tree with an ID, but if this feature is set there's a mismatch: either an item is in the map that has no ID, or an item with an ID is not in the tree. While technically a violation of the requirements in ISO32000, it's probably safe to allow and is not included in the PDF/UA requirements.

        A page or stream in the PDF has a "StructParent" or "StructParents" entry, but there is no StructTreeRoot.ParentTree to resolve this. This is an extremely common and fairly harmless form of damage; on its own, it usually indicates the StructureTree was removed but the pages not cleaned up (not part of basic profile)
