Properties

CheckSum

Gets or sets a 16-byte string that is the checksum of the bytes of the uncompressed embedded file. The checksum is calculated by applying the standard MD5 message-digest algorithm to the bytes of the embedded file stream. Checksum calculated automatically when EmbeddedFileStream created with FromFile(GcPdfDocument, string) or FromBytes(GcPdfDocument, byte[]) methods.

public byte[] CheckSum { get; set; }

Property Value

byte[]

CreationDate

Gets or sets the date and time when the embedded file was created.

public PdfDateTime? CreationDate { get; set; }

Property Value

PdfDateTime?

MimeType

Gets or sets the file's MIME type.

public string MimeType { get; set; }

Property Value

string

ModificationDate

Gets or sets the date and time when the embedded file was last modified.

public PdfDateTime? ModificationDate { get; set; }

Property Value

PdfDateTime?

Size

Gets or sets the size of the embedded file, in bytes.

public int? Size { get; set; }

Property Value

int?
