PdfDocumentProcessor.CreateBitmap(Int32, Int32) Method
Exports a PDF page to a bitmap image.
Namespace: DevExpress.Pdf
Assembly: DevExpress.Docs.v24.2.dll
NuGet Package: DevExpress.Document.Processor
#Declaration
#Parameters
Name | Type | Description |
---|---|---|
page |
Int32 | A page number. |
largest |
Int32 | A length of the image’s largest dimension, in pixels. |
#Returns
Type | Description |
---|---|
Bitmap | 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.
Warning
The Create
method uses GDI/GDI+ rendering and works only on Windows OS. The Platform
is thrown on other operating systems. Use the Create
method in non-Windows environments.
#Example
The following example illustrates how to convert pages to bitmap images.
using DevExpress.Pdf;
using System.Drawing;
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.
Bitmap image = processor.CreateBitmap(i, largestEdgeLength);
// Save the bitmaps.
image.Save("..\\..\\MyBitmap" + i + ".bmp");
}
}
}
