# Write Bitmap To PDF Memory Friendly

Saved bitmap to PDF format using memory-friendly Pipeline API.

## Instruction

Write a C# program that reads a JPEG image and saves it to a PDF format using a memory-friendly Pipeline API.

## Usings

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

## Code Snippet

```csharp
using (var reader = new JpegReader("Chicago.jpg"))
using (var writer = new PdfWriter("WritePdfMemoryFriendly.pdf"))
{
    Pipeline.Run(reader + writer);
}
```

## Explanation

Below is a C# code sample that demonstrates how to read a JPEG image and save it to a PDF using a memory-friendly approach with the Pipeline API:

This code reads an image from a JPEG file and writes it to a PDF document without loading the entire image into memory at once, making the operation more memory efficient.
