PdfDocumentProcessor.CreateDXBitmap(Int32, Int32) Method

Exports a PDF page to a bitmap image. Use this method in non-Windows environments.

Namespace: DevExpress.Pdf

Assembly: DevExpress.Docs.v23.2.dll

NuGet Package: DevExpress.Document.Processor

Declaration

C#

public DXBitmap CreateDXBitmap(
    int pageNumber,
    int largestEdgeLength
)

VB.NET

Public Function CreateDXBitmap(
    pageNumber As Integer,
    largestEdgeLength As Integer
) As DXBitmap

Parameters

Name	Type	Description
pageNumber	Int32	A page number.
largestEdgeLength	Int32	A length of the image’s largest dimension, in pixels.

Returns

Type	Description
DXBitmap	The converted page.

Remarks

The largestEdgeLength parameter determines the output image height for pages in the portrait orientation and width – for landscape pages. The page is proportionally scaled so that the largest edge of the converted bitmap is equal to the largestEdgeLength value.

You can reduce the output image size and memory consumption if you pass a smaller largestEdgeLength value to the CreateBitmap method.

Example

C#

using DevExpress.Drawing;
using DevExpress.Pdf;

static void Main(string[] args) {

    int largestEdgeLength = 1000;

    using (PdfDocumentProcessor processor = new PdfDocumentProcessor()) {
        // Load a document.
        processor.LoadDocument("..\\..\\Document.pdf");

        for (int i = 1; i <= processor.Document.Pages.Count; i++) {
            // Export pages to bitmaps.
            DXBitmap image = processor.CreateDXBitmap(i, largestEdgeLength);

            // Save the bitmaps.
            image.Save("..\\..\\MyBitmap" + i + ".bmp", DXImageFormat.Bmp);
        }
    }
}

VB.NET

Imports DevExpress.Drawing
Imports DevExpress.Pdf

Shared Sub Main(ByVal args() As String)

    Dim largestEdgeLength As Integer = 1000

    Using processor As New PdfDocumentProcessor()
        ' Load a document.
        processor.LoadDocument("..\..\Document.pdf")

        For i As Integer = 1 To processor.Document.Pages.Count
            ' Export pages to bitmaps.
            Dim image As DXBitmap = processor.CreateDXBitmap(i, largestEdgeLength)

            ' Save the bitmaps.
            image.Save("..\..\MyBitmap" & i & ".bmp", DXImageFormat.Bmp)
        Next i
    End Using
