Namespace: Patagames.Pdf
Assembly: Patagames.Pdf (in Patagames.Pdf.dll) Version: 4.94.2704
Syntaxpublic static void FPDFPageObj_SetTextKnockoutFlag( IntPtr page_obj, bool flag )
Public Shared Sub FPDFPageObj_SetTextKnockoutFlag ( page_obj As IntPtr, flag As Boolean )
public: static void FPDFPageObj_SetTextKnockoutFlag( IntPtr page_obj, bool flag )
static member FPDFPageObj_SetTextKnockoutFlag : page_obj : IntPtr * flag : bool -> unit
public static void FPDFPageObj_SetTextKnockoutFlag( IntPtr page_obj, boolean flag )
Patagames.Pdf.Pdfium.FPDFPageObj_SetTextKnockoutFlag = function(page_obj, flag);
Parameters
- page_obj IntPtr
- A handle to a page object. Returned by FPDFPageObj_Create(PageObjectTypes) or FPDFPage_GetObject(IntPtr, Int32)
- flag Boolean
- The text knockout flag to be set.
Remarks
If its value is false, each glyph in a text object is treated as a separate elementary object; when glyphs overlap, they composite with one another.
If the parameter is true, all glyphs in the text object are treated together as a single elementary object; when glyphs overlap, later glyphs overwrite(“knock out”) earlier ones in the area of overlap.
