Convert Transparent PNG to JPG with Non-Black Background Color

Question

I\'m using System.Drawing.Image in .Net to do a simple conversion from png to jpeg. I\'m basically just using these two lines of code:

Image img = Image.Fro         


        

Answer 1

// Assumes myImage is the PNG you are converting
using (var b = new Bitmap(myImage.Width, myImage.Height)) {
    b.SetResolution(myImage.HorizontalResolution, myImage.VerticalResolution);

    using (var g = Graphics.FromImage(b)) {
        g.Clear(Color.White);
        g.DrawImageUnscaled(myImage, 0, 0);
    }

    // Now save b as a JPEG like you normally would
}
