Removal |
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 RemoveSignatureAppearances).
public class RemovalOptions : NativeObject
The RemovalOptions type exposes the following members.
Name | Description | |
---|---|---|
Annotations | The conversion strategy for annotations The conversion strategy for annotations. Annotations in PDF are interactive elements on the pages, such as:
Note that this does not include form fields (see FormFields) and links (see Links). Default: Copy in all profiles. | |
FormFields | The conversion strategy for interactive forms Default: Copy in all profiles. | |
Links | The conversion strategy for links Default: Copy in all profiles. | |
RemoveAlternateImages | Whether to remove additional or alternative versions of images Default: except in the profile Print. | |
RemoveArticleThreads | Whether to remove the sequential flows (threads) of articles Default: except in the profile Archive. | |
RemoveMetadata | Whether to remove document's XMP metadata Default:
| |
RemoveOutputIntents | 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: except in the profile MinimalFileSize. | |
RemovePieceInfo | 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: except in the profile Archive. | |
RemoveSignatureAppearances | Whether to remove or flatten signature appearances A signature in a PDF consist of two parts:
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: Flatten in all profiles. | |
RemoveStructureTree | 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: except in the profile Archive. | |
RemoveThumbnails | Whether to remove thumbnail images which represent the PDF pages in miniature form Default: in all profiles. |
