To create a BMP image from a page in a PDF document, follow the steps below:

1. Create a `GdPicturePDF` object and a `GdPictureImaging` object.

2. Load the source document by passing its path to the `LoadFromFile` method of the `GdPicturePDF` object.

3. Select the page that you want to convert to an image with the `SelectPage` method of the `GdPicturePDF` object.

4. Render the selected page to a 200 dots-per-inch (DPI) image with the `RenderPageToGdPictureImageEx` method of the `GdPicturePDF` object.

5. Save the output in a BMP image with the `SaveAsBMP` method.

The example below creates a BMP image from the first page of a PDF document:

### C#

```csharp

using GdPicturePDF gdpicturePDF = new GdPicturePDF();
using GdPictureImaging gdpictureImaging = new GdPictureImaging();
// Load the source PDF document.
gdpicturePDF.LoadFromFile(@"C:\temp\source.pdf");
// Select the first page of the PDF.
gdpicturePDF.SelectPage(1);
// Render the selected page to an image.
int imageId = gdpicturePDF.RenderPageToGdPictureImageEx(200, true);
// Save the output in a BMP image.
gdpictureImaging.SaveAsBMP(imageId, @"C:\temp\output.bmp");
// Release unnecessary resources.
gdpictureImaging.ReleaseGdPictureImage(imageId);
gdpicturePDF.CloseDocument();

```

### VB.NET

```vb

Using gdpicturePDF As GdPicturePDF = New GdPicturePDF()
Using gdpictureImaging As GdPictureImaging = New GdPictureImaging()
    ' Load the source PDF document.
    gdpicturePDF.LoadFromFile("C:\temp\source.pdf")
    ' Select the first page of the PDF.
    gdpicturePDF.SelectPage(1)
    ' Render the selected page to an image.
    Dim imageId As Integer = gdpicturePDF.RenderPageToGdPictureImageEx(200, True)
    ' Save the output in a BMP image.
    gdpictureImaging.SaveAsBMP(imageId, "C:\temp\output.bmp")
    ' Release unnecessary resources.
    gdpictureImaging.ReleaseGdPictureImage(imageId)
    gdpicturePDF.CloseDocument()
End Using
End Using

```
