class pdftools_sdk.optimization.removal_options.RemovalOptions(handle)[source]

Bases: _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 pdftools_sdk.optimization.removal_options.RemovalOptions.remove_signature_appearances ).

property remove_alternate_images: bool

Whether to remove additional or alternative versions of images

Default is False except in the profile pdftools_sdk.optimization.profiles.print.Print .

Returns:

bool

property remove_article_threads: bool

Whether to remove the sequential flows (threads) of articles

Default is True except in the profile pdftools_sdk.optimization.profiles.archive.Archive .

Returns:

bool

property remove_metadata: bool

Whether to remove document’s XMP metadata

Default:

Returns:

bool

property remove_output_intents: bool

Whether to remove all output intents

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 is False except in the profile pdftools_sdk.optimization.profiles.minimal_file_size.MinimalFileSize .

Returns:

bool

property remove_piece_info: bool

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

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

Default is True except in the profile pdftools_sdk.optimization.profiles.archive.Archive .

Returns:

bool

property remove_structure_tree: bool

Whether to remove the data describing the logical structure of a PDF

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 is True except in the profile pdftools_sdk.optimization.profiles.archive.Archive .

Returns:

bool

property remove_thumbnails: bool

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

Default is True in all profiles.

Returns:

bool

property remove_signature_appearances: RemovalStrategy

Whether to remove or flatten signature appearances

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 is pdftools_sdk.optimization.removal_strategy.RemovalStrategy.FLATTEN in all profiles.

Returns:

pdftools_sdk.optimization.removal_strategy.RemovalStrategy

property annotations: ConversionStrategy

The conversion strategy for annotations

The conversion strategy for annotations.

Annotations in PDF are interactive elements on the pages, such as:

  • Sticky notes

  • Free text annotations

  • Line, square, circle, and polygon annotations

  • Highlight, underline and strikeout annotations

  • Stamp annotations

  • Ink annotations

  • File attachment annotation

  • Sound and movie annotations

  • 3D annotations

Note that this does not include form fields (see pdftools_sdk.optimization.removal_options.RemovalOptions.form_fields ) and links (see pdftools_sdk.optimization.removal_options.RemovalOptions.links ).

Default is pdftools_sdk.optimization.conversion_strategy.ConversionStrategy.COPY in all profiles.

Returns:

pdftools_sdk.optimization.conversion_strategy.ConversionStrategy

property form_fields: ConversionStrategy

The conversion strategy for interactive forms

Default is pdftools_sdk.optimization.conversion_strategy.ConversionStrategy.COPY in all profiles.

Returns:

pdftools_sdk.optimization.conversion_strategy.ConversionStrategy

The conversion strategy for links

Default is pdftools_sdk.optimization.conversion_strategy.ConversionStrategy.COPY in all profiles.

Returns:

pdftools_sdk.optimization.conversion_strategy.ConversionStrategy
