# Convert And Write JPEG

Converts to PixelFormat.Format24bppRgb to and saves to JPEG format.

## Instruction

Load an image and convert it to 24bpp RGB pixel format if it is not already in that format. Then, save it as a JPEG file. Use an appropriate image processing library that supports color management.

## Code Snippet

```csharp
using (var bitmap = new Bitmap("Stamp.png"))
{
    // JPEG format supports PixelFormat.Format32bppCmyk and PixelFormat.Format8bppGrayscale
    // for CMYK and grayscale images accordingly
    if (bitmap.PixelFormat != PixelFormat.Format24bppRgb)
    {
        bitmap.ColorManagement.Convert(PixelFormat.Format24bppRgb);
    }

    bitmap.Save("ConvertAndWriteJpeg.jpg");
}
```

## Explanation

Here is a C# program that checks the pixel format of an image and converts it to 24bpp RGB before saving it as a JPEG:

This code loads the `Stamp.png` image, ensures it is in the `PixelFormat.Format24bppRgb` format (which is required for saving as a standard JPEG), and saves the result as `ConvertAndWriteJpeg.jpg`.
