Syntax

TypeScript

JavaScript

lt.Document.DocumentRedactionMode = { 
   none: 0, 
   apply: 1, 
   applyThenRasterize: 2 
}

lt.Document.DocumentRedactionMode = { 
   none: 0, 
   apply: 1, 
   applyThenRasterize: 2 
}

Members

Value	Member	Description
none	0	Do not apply any annotations. Default behavior. All annotations are visible and live when viewing or converting.
