Example





In This Topic
SetTextWordSpacing Method (GdPicturePDF)
In This Topic
Sets the word spacing to be used when drawing text on the currently loaded PDF document. This value defines a distance between adjacent words in a line of text. It is a number expressed in unscaled text space units (points). The initial value is set to 0.

The word spacing 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 SetTextWordSpacing( _
   ByVal WordSpacing As Single _
) As GdPictureStatus
public GdPictureStatus SetTextWordSpacing( 
   float WordSpacing
)
public function SetTextWordSpacing( 
    WordSpacing: Single
): GdPictureStatus; 
public function SetTextWordSpacing( 
   WordSpacing : float
) : GdPictureStatus;
public: GdPictureStatus SetTextWordSpacing( 
   float WordSpacing
) 
public:
GdPictureStatus SetTextWordSpacing( 
   float WordSpacing
) 

Parameters

WordSpacing
A new word spacing to set. Initial value is 0.

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.

Word spacing is applied to every occurrence of the single-byte character code 32 (space character) in a string.

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