SetLineNoDash Method (GdPicturePDF)

In This Topic
Removes (resets) the currently defined dash pattern previously set by the SetLineDash(Single,Single) method to the initial value, which is a solid line. The dash pattern is used when paths are stroked, for example, when you use the DrawLine method or the DrawRectangle method.

The line dash pattern parameter is one of the graphics state parameters. These parameters are initialized to their default values at the beginning of each page (see PDF Reference, Section "Graphics State").

Syntax
'Declaration
 

Public Function SetLineNoDash() As GdPictureStatus
public GdPictureStatus SetLineNoDash()
public function SetLineNoDash(): GdPictureStatus; 
public function SetLineNoDash() : GdPictureStatus;
public: GdPictureStatus SetLineNoDash(); 
public:
GdPictureStatus SetLineNoDash();

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.

Just to remind you that setting all parameters to zero when using the SetLineDash(Single,Single) method restores the dash pattern to a solid line in the same way like using the SetLineNoDash method.

Be aware also that graphics state parameters are initialized to their default values at the beginning of each page.
