# Write EXIF and IPTC (Memory Friendly)

Writes EXIF and IPTC metadata using memory-friendly Pipeline API.

## Instruction

Write custom EXIF and IPTC metadata to a JPEG image using memory-friendly pipeline processing.

## Usings

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

## Code Snippet

```csharp
using (var jpegReader = new JpegReader("Chicago.jpg"))
using (var jpegWriter = new JpegWriter("WriteExifIptcMemoryFriendly.jpg", 70))
{
    var exif = new ExifDictionary();
    exif[ExifDictionary.Software] = "Aurigma Graphics Mill";
    jpegWriter.Exif = exif;

    var iptc = new IptcDictionary();
    iptc[IptcDictionary.Keyword] = "mountain";
    iptc[IptcDictionary.City] = "Olympia";
    jpegWriter.Iptc = iptc;

    Pipeline.Run(jpegReader + jpegWriter);
}
```

## Explanation

The code:

- Creates a new `JpegReader` to read the input image.
- Sets custom EXIF metadata, including the "Software" tag with the value "Aurigma Graphics Mill".
- Sets custom IPTC metadata, including a keyword "mountain" and a city "Olympia".
- Uses the `Pipeline` to process the image and write the modified metadata to a new JPEG file with the specified quality.
