# Tint Using Alpha (Memory Friendly)

Tints using alpha channel and memory-friendly Pipeline API.

## Instruction

Apply tint using alpha channel and invert colors in a memory-friendly way.

## Usings

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

## Code Snippet

```csharp
// reader  --->  converter  ---> invert  -----\
//                            generator  --->  setAlpha  --->  removeAlpha  --->  writer
using (var reader = ImageReader.Create("Chicago.jpg"))
using (var converter = new Aurigma.GraphicsMill.Transforms.ColorConverter(PixelFormat.Format8bppGrayscale))
using (var invert = new Invert())
using (var generator = new ImageGenerator(reader.Width, reader.Height, PixelFormat.Format24bppRgb, RgbColor.OrangeRed))
using (var setAlpha = new SetAlpha())
using (var removeAlpha = new RemoveAlpha(RgbColor.White))
using (var writer = ImageWriter.Create("TintUsingAlphaMemoryFriendly.jpg"))
{
    setAlpha.AlphaSource = reader + converter + invert;

    Pipeline.Run(generator + setAlpha + removeAlpha + writer);
}
```

## Explanation

The code:

- Reads the image from "Chicago.jpg".
- Converts the image to 8bpp grayscale format and inverts the colors.
- Creates an orange-red background image generator with the same size as the input.
- Sets the alpha channel from the processed image (grayscale and inverted).
- Removes the white color from the alpha channel for transparency.
- Saves the result to "TintUsingAlphaMemoryFriendly.jpg".
