<static> AnnotationOutputFlag

Type:

number

Properties:

Name	Type	Description
`e_internal_xfdf`	number	include the annotation file in the XOD output. This is the default option
`e_external_xfdf`	number	output the annotation file externally to the same output path with extension .xfdf. This is not available when using streaming conversion
`e_flatten`	number	flatten all annotations that are not link annotations

<static> FlattenFlag

Type:

number

Properties:

Name	Type	Description
`e_off`	number	Disable flattening and convert all content as is.
`e_simple`	number	Feature reduce PDF to a simple two layer representation consisting of a single background RGB image and a simple top text layer.
`e_fast`	number	Feature reduce PDF while trying to preserve some complex PDF features (such as vector figures, transparency, shadings, blend modes, Type3 fonts etc.) for pages that are already fast to render. This option can also result in smaller & faster files compared to e_simple, but the pages may have more complex structure.
`e_high_quality`	number	Preserve vector content where possible. In particular only feature reduce PDF files containing overprint or very complex vector content. Currently this option can only be used with XODOutputOptions.

<static> FlattenThresholdFlag

Type:

number

Properties:

Name	Type	Description
`e_very_strict`	number	Render (flatten) any text that is clipped or occluded.
