Export(ImGearRasterPage,Int32,Int32) Method

In This Topic

Exports content of raster page to managed GDI+ image.

Syntax

Visual Basic
C#
Managed Extensions for C++
C++/CLI

'Declaration
 
Public Overloads Shared Function Export( _
   ByVal page As ImGearRasterPage, _
   ByVal ppmX As Integer, _
   ByVal ppmY As Integer _
) As Bitmap

'Usage
 
Dim page As ImGearRasterPage
Dim ppmX As Integer
Dim ppmY As Integer
Dim value As Bitmap
 
value = ImGearRasterProcessing.Export(page, ppmX, ppmY)

public static Bitmap Export( 
   ImGearRasterPage page,
   int ppmX,
   int ppmY
)

public: static Bitmap* Export( 
   ImGearRasterPage* page,
   int ppmX,
   int ppmY
)

public:
static Bitmap^ Export( 
   ImGearRasterPage^ page,
   int ppmX,
   int ppmY
)

Parameters

page: Raster page to be exported.
ppmX: Specifies horizontal resolution of resulting GDI+ bitmap object. Measurement unit is PPM, i.e., pixels per meter.
ppmY: Specifies vertical resolution of resulting GDI+ bitmap object. Measurement unit is PPM, i.e., pixels per meter.

Return Value

An instance of System.Drawing.Bitmap class.

Remarks

Since Bitmap stores pixels in RGB or Indexed format only, color space conversion is used to transfer image data.

Example

C#
Visual Basic

// Source rectangle to export.
ImGearRectangle igRectangleSource = new ImGearRectangle(igRasterPage.DIB.Width, igRasterPage.DIB.Height);
// Destination rectangle to export.
ImGearRectangle igRectangleDestination = new ImGearRectangle(32, 32);
ImGearChannelRange igChannelRange = new ImGearChannelRange(0, igRasterPage.DIB.ChannelCount);
// Export the image to a bitmap and assign that to a standard picturebox.
Bitmap bitmapExport = ImGearRasterProcessing.Export(igRasterPage, 2834, 2834);
bitmapForm.pictureBox1.Image = bitmapExport;

' Source rectangle to export.
Dim igRectangleSource As New ImGearRectangle(igRasterPage.DIB.Width, igRasterPage.DIB.Height)
' Destination rectangle to export.
Dim igRectangleDestination As New ImGearRectangle(32, 32)
Dim igChannelRange As New ImGearChannelRange(0, igRasterPage.DIB.ChannelCount)
' Export the image to a bitmap and assign that to a standard picturebox.
Dim bitmapExport As Bitmap = ImGearRasterProcessing.Export(igRasterPage, 2834, 2834)
bitmapForm1.PictureBox1.Image = bitmapExport
