Namespace:  Atalasoft.Imaging.Codec.Pdf
Assembly:  Atalasoft.dotImage.PdfReader (in Atalasoft.dotImage.PdfReader.dll) Version: 11.4.0.9.0.377 (.NET 4.5.2, x86)
Syntax
Copy
public ExtractedImageInfo[] ExtractImages()

Return Value

Type: ExtractedImageInfo
Extracted images. Can be of zero length.
Remarks
This method will extract each image embedded in a specified page. The method is more efficient for single image PDF pages as it does not resample the image to fit in the indicated resolution.
Examples
C#
Copy
using (FileStream file = new FileStream( 
   string.Format(@"in.pdf", fileName), FileMode.Open, FileAccess.Read))
{
   Document document = new Document(new BinaryReader(file));
   for (int pageIndex=0; pageIndex<document.Pages.Count; pageIndex++)
   {
      Page page = document.Pages[pageIndex];
      ExtractedImageInfo[] images = page.ExtractImages();
      for (int imageIndex=0; null!=images && imageIndex<images.Length; imageIndex++)
      {
         images[imageIndex].Bitmap.Save( 
            string.Format(@"..\..\out_{0}_{1}.bmp", pageIndex, imageIndex));
      }
   }
}
