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(0Spire.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); }

Hiajit. 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
