How to convert gif images to jpeg in c# code winforms?

I am trying to convert my gif/png images to jpeg then after that i want to pass these images to sqldatabase. Because crystal report doesnot support gif images for displaying as a report.

So now i have a problem to covert gif images to jpeg.

Sample code:

data = File.ReadAllBytes(ImgPath);

data is byte[] type so i have image path now i want to convert into jpeg before ReadAllBytes() callls

I tried like this :

   using (Image img = Image.FromFile(ImgPath))
   {
             img.Save(ImgPath, System.Drawing.Imaging.ImageFormat.Jpeg);
   }

But i got Generic error Gdi something is came. thanks.

I think you can go even simpler than bdn02's answer. Try:

Image img = Image.FromFile(@"c:\temp_10\sample.gif");
img.Save(@"c:\temp_10\sample.jpg", ImageFormat.Jpeg);

This is the code:

        byte[] imagebuffer;

        using (Image img = Image.FromFile(@"c:\temp_10\sample.gif"))
        using (MemoryStream ms = new MemoryStream())
        {
            img.Save(ms, ImageFormat.Jpeg);
            imagebuffer = ms.ToArray();
        }

        //write to fs (if you need...)
        File.WriteAllBytes(@"c:\temp_10\sample.jpg", imagebuffer);

The namespace to use is System.Drawing

I've modified my code, i think that you don't need the file on filesystem but you can use the byte array to call Crystal report

Here are two places that can help. One is Microsoft's site on how to read in image files to memory.

https://msdn.microsoft.com/en-us/library/twss4wb0(v=vs.90).aspx

The next is an example from another user on the site on how to read the file into a bite array as the format you want. I am assuming you want it as a byte array so you can do something with it rather than put it back down as a file.

How to convert image in byte array

I would have typed it all out but found the examples and they were self explanatory. :-)
