SetFillColor(Color) Method

In This Topic

Sets the fill color used by all subsequent filling operations, like the DrawRectangle method. The initial value is set to black.

The fill color 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").

'Declaration

 

Public Overloads Function SetFillColor( _

   ByVal FillColor As Color _

) As GdPictureStatus

public GdPictureStatus SetFillColor( 

   Color FillColor

)

public function SetFillColor( 

    FillColor: Color

): GdPictureStatus;

public function SetFillColor( 

   FillColor : Color

) : GdPictureStatus;

public: GdPictureStatus SetFillColor( 

   Color FillColor

)

public:

GdPictureStatus SetFillColor( 

   Color FillColor

)

Parameters

FillColor: A color object that defines the new fill color. Initial value: black.

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.

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