# Write Animated Gif

Writes simple animated image in GIF format.

## Instruction

Create an animated GIF by generating multiple frames programmatically. Each frame should contain a green circle drawn at a different horizontal position on a yellow background. Use the memory-friendly Pipeline API to write the animation.

## Usings

```csharp
using Aurigma.GraphicsMill.Codecs;
using Aurigma.GraphicsMill.Drawing;
```

## Code Snippet

```csharp
using (var writer = new GifWriter("WriteAnimatedGif.gif"))
{
    writer.Width = 400;
    writer.Height = 100;
    writer.FrameOptions.Delay = 25;

    for (int i = 0; i < 400; i += 25)
    {
        var bitmap = new Bitmap(400, 100, PixelFormat.Format24bppRgb, RgbColor.Yellow);

        using (var graphics = bitmap.GetGraphics())
        {
            graphics.FillEllipse(new SolidBrush(RgbColor.Green), new System.Drawing.RectangleF(i, 0, 100, 100));
        }

        bitmap.ColorManagement.Convert(PixelFormat.Format8bppIndexed);

        Pipeline.Run(bitmap + writer);
    }
}
```

## Explanation

Here is a C# program that generates an animated GIF with a moving green circle on a yellow background:

This code creates an animated GIF `WriteAnimatedGif.gif` that is 400x100 pixels in size. It draws a green circle moving horizontally across a yellow background by generating frames in a loop. Each frame is converted to 8-bit indexed format and added to the GIF using the memory-efficient Pipeline API.
