Class RemovalOptions

  • public class RemovalOptions
extends NativeObject

    The parameters defining the optional data to remove or flatten

    Removal options specify the PDF data structures to copy or remove, e.g. article threads, metadata, or alternate images.

    In addition, the visual appearances of signatures, annotations, form fields, and links can be flattened.

    Flattening means, that the appearance of such a data structure is drawn as non-editable graphic onto the page; for visual appearances of signatures, flattening has a slightly different meaning (see property getRemoveSignatureAppearances()).

        public boolean getRemoveOutputIntents()

        Whether to remove all output intents (Getter)

        Output intents provide a means for matching the color characteristics of PDF page content with those of a target output device or production environment in which the document will be printed.

        Default: false except in the profile profiles.MinimalFileSize.

      • setRemoveOutputIntents

        public void setRemoveOutputIntents​(boolean value)

        Whether to remove all output intents (Setter)

        Output intents provide a means for matching the color characteristics of PDF page content with those of a target output device or production environment in which the document will be printed.

        Default: false except in the profile profiles.MinimalFileSize.

      • getRemovePieceInfo

        public boolean getRemovePieceInfo()

        Whether to remove the piece-info dictionary (private PDF processor data) (Getter)

        The removal of this proprietary application data has no effect on the document's visual appearance.

        Default: true except in the profile profiles.Archive.

      • setRemovePieceInfo

        public void setRemovePieceInfo​(boolean value)

        Whether to remove the piece-info dictionary (private PDF processor data) (Setter)

        The removal of this proprietary application data has no effect on the document's visual appearance.

        Default: true except in the profile profiles.Archive.

      • getRemoveStructureTree

        public boolean getRemoveStructureTree()

        Whether to remove the data describing the logical structure of a PDF (Getter)

        The logical structure of the document is a description of the content of its pages. It consists of a fine granular hierarchical tagging that distinguishes between the actual content and artifacts (such as page numbers, layout artifacts, etc.). The tagging provides a meaningful description, for example "This is a header", "This color image shows a small sailing boat at sunset", etc. This information can be used e.g. to read the document to the visually impaired.

        Default: true except in the profile profiles.Archive.

      • setRemoveStructureTree

        public void setRemoveStructureTree​(boolean value)

        Whether to remove the data describing the logical structure of a PDF (Setter)

        Default: true except in the profile profiles.Archive.

      • getRemoveThumbnails

        public boolean getRemoveThumbnails()

        Whether to remove thumbnail images which represent the PDF pages in miniature form (Getter)

        Default: true in all profiles.

      • setRemoveThumbnails

        public void setRemoveThumbnails​(boolean value)

        Whether to remove thumbnail images which represent the PDF pages in miniature form (Setter)

        Default: true in all profiles.

      • getRemoveSignatureAppearances

        public RemovalStrategy getRemoveSignatureAppearances()

        Whether to remove or flatten signature appearances (Getter)

        A signature in a PDF consist of two parts:

        • (a) The invisible digital signature in the PDF.
        • (b) The visual appearance that was attributed to the signature.

        Part (a) can be used by a viewing application, to verify that the PDF has not changed since it has been signed and report this to the user.

        During optimizing, the PDF is altered and hence its digital signature (a) is broken and must be removed.

        Default: RemovalStrategy.FLATTEN in all profiles.

      • setRemoveSignatureAppearances

        public void setRemoveSignatureAppearances​(RemovalStrategy value)

        Whether to remove or flatten signature appearances (Setter)

        A signature in a PDF consist of two parts:

        • (a) The invisible digital signature in the PDF.
        • (b) The visual appearance that was attributed to the signature.
