PrintSetPreRasterizationDPI Method (GdPicturePDF)

In This Topic

Specifies the rendering resolution to be used when pre-rasterization is enabled using the GdPicturePDF.PrintSetPreRasterization method. Enabling the pre-rasterization and setting the proper DPI can dramatically improve the performance with printer drivers non-optimized for vector graphics rendering.

Syntax

Visual Basic
C#
Delphi
JScript

C++/CLI

'Declaration
 
Public Function PrintSetPreRasterizationDPI( _
   ByVal DPI As Single _
) As GdPictureStatus

public GdPictureStatus PrintSetPreRasterizationDPI( 
   float DPI
)

public function PrintSetPreRasterizationDPI( 
    DPI: Single
): GdPictureStatus;

public function PrintSetPreRasterizationDPI( 
   DPI : float
) : GdPictureStatus;

public: GdPictureStatus PrintSetPreRasterizationDPI( 
   float DPI
)

public:
GdPictureStatus PrintSetPreRasterizationDPI( 
   float DPI
)

Parameters

DPI: The rendering resolution to be used for pre-rasterization. The default value is -1, which means automatic computation based on printing quality.

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.

Example

Setting the pre-rasterization DPI to speed up the print process.

VB.NET
C#

Using gdpicturePDF As New GdPicturePDF()
    gdpicturePDF.LoadFromFile("document_to_print.pdf", False)
    'Enabling the pre-rasterization option.
    gdpicturePDF.PrintSetPreRasterization(True)
    'Setting the pre-rasterization DPI.
    gdpicturePDF.PrintSetPreRasterizationDPI(300)
    gdpicturePDF.Print()
    gdpicturePDF.CloseDocument()
End Using

using (GdPicturePDF gdpicturePDF = new GdPicturePDF())
{
    gdpicturePDF.LoadFromFile("document_to_print.pdf", false);
    //Enabling the pre-rasterization option.
    gdpicturePDF.PrintSetPreRasterization(true);
    //Setting the pre-rasterization DPI.
    gdpicturePDF.PrintSetPreRasterizationDPI(300);
    gdpicturePDF.Print();
    gdpicturePDF.CloseDocument();
}

Example

Setting the pre-rasterization DPI to speed up the print process. Using gdpicturePDF As New GdPicturePDF() gdpicturePDF.LoadFromFile("document_to_print.pdf", False) 'Enabling the pre-rasterization option. gdpicturePDF.PrintSetPreRasterization(True) 'Setting the pre-rasterization DPI. gdpicturePDF.PrintSetPreRasterizationDPI(300) gdpicturePDF.Print() gdpicturePDF.CloseDocument() End Using using (GdPicturePDF gdpicturePDF = new GdPicturePDF()) { gdpicturePDF.LoadFromFile("document_to_print.pdf", false); //Enabling the pre-rasterization option. gdpicturePDF.PrintSetPreRasterization(true); //Setting the pre-rasterization DPI. gdpicturePDF.PrintSetPreRasterizationDPI(300); gdpicturePDF.Print(); gdpicturePDF.CloseDocument(); }
