Methods

public PdfLoadOptions Clone() #
PdfLoadOptions.Snapshot.cs:5
Returns: PdfLoadOptions

Snapshots all load settings and resource limits. The caller-supplied AES provider is retained.

Properties

public static PdfLoadOptions Default { get; } #
PdfLoadOptions.cs:10

Creates default read settings with an independent limits graph.

public PdfParsingMode ParsingMode { get; init; } #
PdfLoadOptions.cs:13

Structural parsing policy. Lenient recovery is the compatibility default and always produces a repair report.

public PdfReadLimits Limits { get; init; } #
PdfLoadOptions.cs:16

Resource budgets for object scanning and raw stream allocation.

public String? Password { get; init; } #
PdfLoadOptions.cs:22

Password used to open encrypted PDFs. The same value is tried as user and owner password for Standard security handler files. For Standard security revisions 5 and 6, passwords longer than 4096 UTF-16 characters are rejected before normalization.

public IOfficeAesCryptographyProvider? AesCryptographyProvider { get; init; } #
PdfLoadOptions.cs:27

Optional synchronous AES provider used to open Standard-security PDFs when platform AES-CBC is unavailable.

public PdfPermissionPolicy PermissionPolicy { get; init; } #
PdfLoadOptions.cs:33

Controls whether authenticated user-password permission restrictions are enforced. Ignoring restrictions still requires the PDF to be successfully decrypted with a valid password.

public Boolean PreferToUnicode { get; init; } #
PdfLoadOptions.cs:35

Prefer decoding via ToUnicode CMap when available. Default: true.

public Boolean UseWinAnsiFallback { get; init; } #
PdfLoadOptions.cs:37

Fallback to WinAnsi (Windows-1252) when no ToUnicode is present. Default: true.

public Boolean AdjustKerningFromTJ { get; init; } #
PdfLoadOptions.cs:39

Adjust X position using TJ kerning values (thousandths of font size). Default: true.

public Boolean IncludeArtifactText { get; init; } #
PdfLoadOptions.cs:44

Includes text inside PDF artifact marked-content sequences, such as page headers, footers, and chart decorations. Default: false, which returns logical document text.
