A member of the PdfTextMode enumeration. A new text rendering mode to set. Initial value is PdfTextMode.PdfTextModeFill.

This value is defined for use with any font you choose.

Example





In This Topic
SetTextMode Method (GdPicturePDF)
In This Topic
Sets the text rendering mode to be used when drawing text onto the currently loaded PDF document. The text rendering mode specifies whether drawing text causes glyph outlines to be stroked, filled, used as a clipping boundary, or some combination of the three. The initial value is set to fill mode.

The text rendering mode parameter is one of the text state parameters, that only affect text. The text state parameters are initialized to their default values at the beginning of each page (see PDF Reference, Section "Text State Parameters and Operators").

Syntax
'Declaration
 

Public Function SetTextMode( _
   ByVal TextMode As PdfTextMode _
) As GdPictureStatus
public GdPictureStatus SetTextMode( 
   PdfTextMode TextMode
)
public function SetTextMode( 
    TextMode: PdfTextMode
): GdPictureStatus; 
public function SetTextMode( 
   TextMode : PdfTextMode
) : GdPictureStatus;
public: GdPictureStatus SetTextMode( 
   PdfTextMode TextMode
) 
public:
GdPictureStatus SetTextMode( 
   PdfTextMode TextMode
)

Parameters

TextMode
A member of the PdfTextMode enumeration. A new text rendering mode to set. Initial value is PdfTextMode.PdfTextModeFill.

This value is defined for use with any font you choose.

Return Value

A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK.

We strongly recommend always checking this status first.

Remarks
This method is only allowed for use with non-encrypted documents.

As being noticed above, be aware that the text state parameters are initialized to their default values at the beginning of each page.
