Hi You can do in this way Class to convert. public class TiffImage { private string myPath; private Guid myGuid; private FrameDimension myDimension; public ArrayList myImages = new ArrayList(); private int myPageCount; private Bitmap myBMP; public TiffImage( string path) { MemoryStream ms; Image myImage; myPath = path; FileStream fs = new FileStream(myPath, FileMode.Open); myImage = Image.FromStream(fs); myGuid = myImage.FrameDimensionsList[0]; myDimension = new FrameDimension(myGuid); myPageCount = myImage.GetFrameCount(myDimension); for ( int i = 0; i { ms = new MemoryStream(); myImage.SelectActiveFrame(myDimension, i); myImage.Save(ms, ImageFormat.Bmp); myBMP = new Bitmap(ms); myImages.Add(myBMP); ms.Close(); } fs.Close(); } } How to use it. private void button1_Click( object sender, EventArgs e) { TiffImage myTiff = new TiffImage( "D:\Some.tif" ); //imageBox is a PictureBox control, and the [] operators pass back //the Bitmap stored at that position in the myImages ArrayList in the TiffImage this .pictureBox1.Image = (Bitmap)myTiff.myImages[0]; this .pictureBox2.Image = (Bitmap)myTiff.myImages[1]; this .pictureBox3.Image = (Bitmap)myTiff.myImages[2]; }

You can use the ConvertToImage method to convert a PDF file to a suitable System.Drawing.Image object. You should also try checking if the source is GDI/GID+ image compatible in the scenario that the source you are using cannot be loaded as an image. You can try the following code to accomplish this: using (RasterCodecs codecs = new RasterCodecs()) { RasterImage image = codecs.Load(@ "C:	est.pdf" ); ImageIncompatibleReason reason = RasterImageConverter.TestCompatible(image, true ); PixelFormat pf = RasterImageConverter.GetNearestPixelFormat(image); Console.WriteLine( "TestCompatible: {0}" , reason); Console.WriteLine( "GetNearestPixelFormat:{0}" , pf); if (reason != ImageIncompatibleReason.Compatible) { RasterImageConverter.MakeCompatible(image, pf, true ); } Image destImage = RasterImageConverter.ConvertToImage(image, ConvertToImageOptions.None)); } https://www.leadtools.com/help/sdk/v22/dh/ld/rasterimageconverter-converttoimage.html https://www.leadtools.com/help/sdk/v22/dh/ld/rasterimageconverter-makecompatible.html
