So I was doing this in WinForms .NET 3.5... I am now using WPF .NET 4.0... and I cant figure out how to do it.

This is what I was doing in Windows .NET 3.5

```
using (Bitmap eventImg = new Bitmap("input.png"))
{
    Graphics eventGfx = Graphics.FromImage(eventImg);

    buildText(eventGfx, this.event1.Text);

    eventImg.Save("output.png", ImageFormat.Png);
    eventGfx.Dispose();
}

```

The above code took the existing image at "input.png", created a new image from it, wrote text from it and then saved the new image at "output.png". Text was written using the following function:

```
private void buildText(Graphics graphic, string text)
{
    if (text.Length == 0) { return; }

    FontStyle weight = FontStyle.Regular;

    switch (this.font_style)
    {
        case "regular":     weight = FontStyle.Regular;     break;
        case "bold":        weight = FontStyle.Bold;        break;
        case "italic":      weight = FontStyle.Italic;      break;
        case "underline":   weight = FontStyle.Underline;   break;
        case "strikeout":   weight = FontStyle.Strikeout;   break;
    }

    using (Font font = new Font(this.font_family, this.font_size, weight, GraphicsUnit.Pixel))
    {
        Rectangle rect = new Rectangle(this.left, this.top, this.width, this.height);
        Brush brush = new SolidBrush(Color.FromArgb(this.font_color));

        StringFormat format = new StringFormat();

        switch (this.align_x)
        {
            case "left":    format.Alignment = StringAlignment.Near;     break;
            case "right":   format.Alignment = StringAlignment.Far;      break;
            default:        format.Alignment = StringAlignment.Center;   break;
        }

        switch (this.align_y)
        {
            case "top":     format.LineAlignment = StringAlignment.Near;    break;
            case "bottom":  format.LineAlignment = StringAlignment.Far;     break;
            default:        format.LineAlignment = StringAlignment.Center;  break;
        }

        graphic.TextRenderingHint = TextRenderingHint.AntiAlias;
        graphic.DrawString(text, font, brush, rect, format);
    }
}

```

However, since System.Drawing does not exist in WPF .NET 4.0, I can't use these functions anymore. How would I do what I am trying to do in WPF .NET 4.0? I've gotten as far as the code below in order to do the first step of making an image based on the old image:

```
using (var fileStream = new FileStream(@"z:\ouput.png", FileMode.Create))
{
    BitmapEncoder encoder = new PngBitmapEncoder();
    encoder.Frames.Add(BitmapFrame.Create(new Uri(@"z:\input.png")));
    encoder.Save(fileStream);
}

```
