Saving a bmp object into the highest quality possible

I have a piece of code that create a heatmap, and everything is saved into a bitmap image. My main method is below. 

        HeatMap map = new HeatMap(colors, width, height, file, U, V);
        _maps.Clear();
        _maps.Add(map);

        Bitmap newBMP = overlayBitmap(map.Image, width * 3, height * 3, times, dates, colors); // resizes the bmp without blending colors

        if (save) {
            newBMP.Save(file, ImageFormat.Png);
        }

HeatMap() is a method that takes in those parameters, creates a bitmap, and stores it into an instance.

overlayBitmap() is a method that takes my previously made map, through some InterpolationMode.NearestNeighbor enlarges the images, and puts text onto this heatmap graph, like x/y-axis labels and title.

Then I use a simple save method.

My question is - what is the best way to save the bmp into the highest quality possible? I opted for .png instead of .jpeg, but are there additional things I can do?

.png is the optimal way of storing a bmp without loosing quality, it is more effective then just zipping a bmp. And not a single pixel is lost.
