How to convert PDF to Image

Question

How to convert PDF to Image using asp.net c# ?

Pranay Kant · Answer

I used free Spire.PDF to convert PDF to Image in C#, but it can only convert 3 pages. static void Main(string[] args) { PdfDocument doc = new PdfDocument(); doc.LoadFromFile("sample.pdf"); Bitmap bmp =doc.SaveAsImage(0); Image emf = doc.SaveAsImage(0,Spire.Pdf.Graphics.PdfImageType.Metafile); Image zoomImg = new Bitmap((int)(emf.Size.Width * 2), (int)(emf.Size.Height * 2)); using (Graphics g = Graphics.FromImage(zoomImg)) { g.ScaleTransform(2.0f, 2.0f); g.DrawImage(emf, new Rectangle(new Point(0, 0), emf.Size), new Rectangle(new Point(0, 0), emf.Size), GraphicsUnit.Pixel); } bmp.Save("convertToBmp.bmp", ImageFormat.Bmp); System.Diagnostics.Process.Start("convertToBmp.bmp"); emf.Save("convertToEmf.png", ImageFormat.Png); System.Diagnostics.Process.Start("convertToEmf.png"); zoomImg.Save("convertToZoom.png", ImageFormat.Png); System.Diagnostics.Process.Start("convertToZoom.png"); }

Its easy to convert a PDF file to Image format (JPEG, JPG or PNG) using GroupDocs.Conversion for .NET. string outputFileTemplate = Path.Combine(outputFolder, "converted-page-{0}.jpg" ); SavePageStream getPageStream = page => new FileStream( string .Format(outputFileTemplate, page), FileMode.Create); using (Converter converter = new Converter( "sample.pdf" )) { ImageConvertOptions options = new ImageConvertOptions { Format = ImageFileType.Jpeg }; converter.Convert(getPageStream, options); } All you have to do is to integrate a single DLL https://downloads.groupdocs.com/conversion/net in your ASP.NET application.

Hi,ajit. I wonder how to deal with these code? Do I need another 3rd party manual toolkit? When it comes to PDF converting process, I have another question, I wonder have you ever tried to convert pdf to other image files before? As for myself, I am testing the related PDF to PNG converting, PDF to BMP converting , and PDF to JPG converting programs these days. Do you have experience about it? Any suggestion will be appreciated. Thanks in advance. Best regards, Pan
