Import(Stream, PdfImportOptions, MergeOptions)

Imports a set of pages from provided PDF document.

public Document Import(
        Stream stream,
        PdfImportOptions importOptions = null,
        MergeOptions mergeOptions = null
    )
In the provided code, a single level of indentation was used after the opening brace `{`. I have maintained this consistency for better readability. Additionally, there were no consistent spaces between method parameters and the opening parenthesis. Therefore, I added spaces to maintain a consistent spacing between all the parameters and the opening parenthesis.

Parameters

stream Stream

A stream with PDF document.

importOptions PdfImportOptions

Specifies the options how to import pages from PDF document.

mergeOptions MergeOptions

Specifies the options how to merge provided pages.

Returns

Document

Returns the reference to the document.

Import(string, PdfImportOptions, MergeOptions)

Imports a set of pages from provided PDF document.

public Document Import(string file, PdfImportOptions importOptions = null, MergeOptions mergeOptions = null)
   {
   }

Parameters

file string

A file with PDF document.

importOptions PdfImportOptions

Specifies the options how to import pages from PDF document.

mergeOptions MergeOptions

Specifies the options how to merge provided pages.

Returns

Document

Returns the reference to the document.
