public final class AProfile
extends PdfProfile

PDF profile checker for PDF/A-1 documents. See 19005-1:2005(E), "Document Imaging Applications Application Issues". Revised to reflect the final standard. With the new terminology, this profile is specific to PDF/A-1; there may be additional standards in the PDF/A family later on. "PDF/A" means "PDF/A-1" in the documentation of this code. There are two levels of conformance, called Level A and Level B. We report these as two different profiles. To accomplish this, we use AProfileLevelA, linked to an instance of this, which simply checks if this profile established Level A compliance.

protected boolean	formObjectOK(PdfDictionary xo) Checks if a Form xobject is valid.
protected boolean	imageObjectOK(PdfDictionary xo) Checks if a single image XObject fits the profile
protected boolean	satisfiesLevelA() Returns true if the document was found to be Level A conformant.
boolean	satisfiesThisProfile() Returns true if the document satisfies the profile at Level B or better.

Constructor Detail

AProfile

public AProfile(PdfModule module)

Constructor. Creates an AProfile object for subsequent testing.

Parameters:

module - The module under which we are checking the profile.

Method Detail

setTaggedProfile

public void setTaggedProfile(TaggedProfile tpr)

Calling setTaggedProfile links this AProfile to a TaggedProfile.

satisfiesThisProfile

public boolean satisfiesThisProfile()

Returns true if the document satisfies the profile at Level B or better. Also sets the level A flag to the appropriate value, so that satisfiesLevelA can subsequently be called.

Specified by:

satisfiesThisProfile in class PdfProfile

satisfiesLevelA

protected boolean satisfiesLevelA()

Returns true if the document was found to be Level A conformant. This returns a meaningful result only after satisfiesThisProfile has been called, and is intended for use by the Level A profiler.

xObjectOK

protected boolean xObjectOK(PdfDictionary xo)

Checks a single XObject for xObjectsOK.

Overrides:

xObjectOK in class PdfProfile

formObjectOK

protected boolean formObjectOK(PdfDictionary xo)

Checks if a Form xobject is valid. This overrides the method in XProfileBase.

imageObjectOK

protected boolean imageObjectOK(PdfDictionary xo)

Checks if a single image XObject fits the profile
