The LEADTOOLS Imaging SDK has a RasterImageConverter Class in the Leadtools.Drawing.dll that will help convert to and from a GDI and GDI+ Image object into a LEADTOOLS RasterImage object.

https://www.leadtools.co...asterimageconverter.html

The 2 methods that do the converting are the ConvertoToImage and ConvertFromImage methods:

ConvertToImage Method
https://www.leadtools.co...rter~converttoimage.html

ConvertFromImage Method
https://www.leadtools.co...er~convertfromimage.html

Here is an example of how to Convert from a RasterImage to a GDI+ Image and then back:

C#
Code:
using(RasterImage srcImage = codecs.Load(srcFileName))
   {
      // Convert to GDI+ image
      ImageIncompatibleReason reason = RasterImageConverter.TestCompatible(srcImage, true);
      PixelFormat pf = RasterImageConverter.GetNearestPixelFormat(srcImage);
      Console.WriteLine("TestCompatible: {0}", reason);
      Console.WriteLine("GetNearestPixelFormat:{0}", pf);

      if(reason != ImageIncompatibleReason.Compatible)
      {
         RasterImageConverter.MakeCompatible(srcImage, pf, true);
      }

      using(Image destImage1 = RasterImageConverter.ConvertToImage(srcImage, ConvertToImageOptions.None))
      {
         // Save this image to disk
         destImage1.Save(destFileName1, ImageFormat.Bmp);

         // Convert the GDI+ image back to a RasterImage
         using(RasterImage destImage2 = RasterImageConverter.ConvertFromImage(destImage1, ConvertFromImageOptions.None))
         {
            // Save it to disk
            codecs.Save(destImage2, destFileName2, RasterImageFormat.Bmp, 24);
         }
      }
   }


VB
Code:
   ' Load the image
   Using srcImage As RasterImage = codecs.Load(srcFileName)
      ' Convert to GDI+ image
      Dim reason As ImageIncompatibleReason = RasterImageConverter.TestCompatible(srcImage, True)
      Dim pf As PixelFormat = RasterImageConverter.GetNearestPixelFormat(srcImage)
      Console.WriteLine("TestCompatible: {0}", reason)
      Console.WriteLine("GetNearestPixelFormat:{0}", pf)

      If reason <> ImageIncompatibleReason.Compatible Then
         RasterImageConverter.MakeCompatible(srcImage, pf, True)
      End If

      Using destImage1 As Image = RasterImageConverter.ConvertToImage(srcImage, ConvertToImageOptions.None)
         ' Save this image to disk
         destImage1.Save(destFileName1, ImageFormat.Bmp)

         ' Convert the GDI+ image back to a RasterImage
         Using destImage2 As RasterImage = RasterImageConverter.ConvertFromImage(destImage1, ConvertFromImageOptions.None)
            ' Save it to disk
            codecs.Save(destImage2, destFileName2, RasterImageFormat.Bmp, 24)
         End Using
      End Using
   End Using
