Fields

Print = 4

For LMKit.Document.Pdf.PdfDocument.SecurityHandlerRevision of 2: Print the document. For LMKit.Document.Pdf.PdfDocument.SecurityHandlerRevision of 3 or greater: Print the document (possibly not at the highest quality level, depending on whether PrintHighQuality is also set).

Modify = 8

Modify the contents of the document by operations other than those controlled by ModifyAnnotations, FillInForms and AssembleDocument.

ExtractTextAndGraphics = 16

For LMKit.Document.Pdf.PdfDocument.SecurityHandlerRevision of 2: Copy or otherwise extract text and graphics from the document, including extracting text and graphics (in support of accessibility to users with disabilities or for other purposes). For LMKit.Document.Pdf.PdfDocument.SecurityHandlerRevision of 3 or greater: Copy or otherwise extract text and graphics from the document by operations other than that controlled by ExtractTextAndGraphics2.

ModifyAnnotations = 32

Add or modify text annotations, fill in interactive form fields, and, if Modify is also set, create or modify interactive form fields (including signature fields).

FillInForms = 256

For LMKit.Document.Pdf.PdfDocument.SecurityHandlerRevision of 3 or greater: Fill in existing interactive form fields (including signature fields), even if ModifyAnnotations is not set.

ExtractTextAndGraphics2 = 512

For LMKit.Document.Pdf.PdfDocument.SecurityHandlerRevision of 3 or greater: Extract text and graphics (in support of accessibility to users with disabilities or for other purposes).

AssembleDocument = 1024

For LMKit.Document.Pdf.PdfDocument.SecurityHandlerRevision of 3 or greater: Assemble the document (insert, rotate, or delete pages and create bookmarks or thumbnail images), even if Modify is not set.

PrintHighQuality = 2048

For LMKit.Document.Pdf.PdfDocument.SecurityHandlerRevision of 3 or greater: Print the document to a representation from which a faithful digital copy of the PDF content could be generated. When PrintHighQuality is not set (and Print is set), printing is limited to a low-level representation of the appearance, possibly of degraded quality.

Examples

Example: Check document permissions.

using LMKit.Document.Pdf;
DocumentPermissions perms = PdfInfo.GetPermissions("protected.pdf");
bool canPrint  = perms.HasFlag(DocumentPermissions.Print);
bool canModify = perms.HasFlag(DocumentPermissions.Modify);
bool canCopy   = perms.HasFlag(DocumentPermissions.ExtractTextAndGraphics);
Console.WriteLine($"Print: {canPrint}, Modify: {canModify}, Copy: {canCopy}");
