public enum class PDFFontStyle

class PDFFontStyle(Enum): 
   Normal = 0 
   Bold = 1 
   Italic = 2 
   Underline = 4

Members

Value	Member	Description
0x00000000	Normal	Normal font
0x00000001	Bold	Bold font
0x00000002	Italic	Italic font
0x00000004	Underline	Underline font

Remarks

The PDFFontStyle is used as the type for the PDFFont.FontStyle property.

The members of PDFFontStyle can be OR'ed together.

You can read the fonts of a PDF page through the PDFDocument.ParsePages method with the PDFParsePagesOptions.Fonts as part of the options parameter. When this method returns, each PDFDocumentPage parsed will have the PDFDocumentPage.Fonts collection populated with the fonts of the page.
