GdPicture.NET.14
GdPicture14 Namespace / GdViewer Class / PrintSetPreRasterization Method
Set this parameter to true if you want to enable the pre-rasterization, otherwise set it to false. The default value is false.
Example





In This Topic
PrintSetPreRasterization Method (GdViewer)
In This Topic
Enables or disables the pre-rasterization parameter which specifies whether the pages of the document currently displayed in the GdViewer control must be pre-rasterized before being printed using the active printer. Enabling the pre-rasterization can dramatically improve the performance with printer drivers non-optimized for vector graphics rendering.

You can also define the rendering resolution using the PrintSetPreRasterizationDPI method when pre-rasterization is enabled.

Syntax
'Declaration
 
Public Function PrintSetPreRasterization( _
   ByVal PreRasterization As Boolean _
) As GdPictureStatus
public GdPictureStatus PrintSetPreRasterization( 
   bool PreRasterization
)
public function PrintSetPreRasterization( 
    PreRasterization: Boolean
): GdPictureStatus; 
public function PrintSetPreRasterization( 
   PreRasterization : boolean
) : GdPictureStatus;
public: GdPictureStatus PrintSetPreRasterization( 
   bool PreRasterization
) 
public:
GdPictureStatus PrintSetPreRasterization( 
   bool PreRasterization
) 

Parameters

PreRasterization
Set this parameter to true if you want to enable the pre-rasterization, otherwise set it to false. The default value is false.

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
It is recommend to use the GetStat method or the PrintGetStat method to identify the specific reason for the method's failure, if any.

Just to remind you that the active printer is the printer identified by the PrintGetActivePrinter method or set by the PrintSetActivePrinter method and it is dedicated to executing all subsequent print jobs using this class as well as utilizing all by you altered printer settings.

Example
Printing a file using the pre-rasterization feature.
// Display a file in the integrated GdViewer1 control.
GdViewer1.DisplayFromFile(""); // An empty string allows the control to prompt for selecting a file.
 
// Enable the pre-rasterization option.
GdViewer1.PrintSetPreRasterization(true);
GdViewer1.PrintSetPreRasterizationDPI(300);
 
// Print a file.
GdViewer1.Print();
 
GdViewer1.CloseDocument();
' Display a file in the integrated GdViewer1 control.
GdViewer1.DisplayFromFile("") ' An empty String allows the control To prompt For selecting a file.
 
' Enable the pre-rasterization option.
GdViewer1.PrintSetPreRasterization(True)
GdViewer1.PrintSetPreRasterizationDPI(300)
 
' Print a file.
GdViewer1.Print()
 
GdViewer1.CloseDocument()
