Title: Canvas Image
|
|
Order: 70
|
|
Description: "Use *ImageSharp* to parse images and render them as Ascii art to the console."
|
|
Reference: T:Spectre.Console.CanvasImage
|
|
---
|
|
|
|
To add [ImageSharp](https://github.com/SixLabors/ImageSharp) superpowers to
|
|
your console application to draw images, you will need to install
|
|
the [Spectre.Console.ImageSharp](https://www.nuget.org/packages/Spectre.Console.ImageSharp) NuGet package.
|
|
|
|
```text
|
|
> dotnet add package Spectre.Console.ImageSharp
|
|
```
|
|
|
|
## Loading images
|
|
|
|
Once you've added the `Spectre.Console.ImageSharp` NuGet package,
|
|
you can create a new instance of `CanvasImage` to draw images to the console.
|
|
|
|
```csharp
|
|
// Load an image
|
|
var image = new CanvasImage("cake.png");
|
|
|
|
// Set the max width of the image.
|
|
// If no max width is set, the image will take
|
|
// up as much space as there is available.
|
|
image.MaxWidth(16);
|
|
|
|
// Render the image to the console
|
|
AnsiConsole.Write(image);
|
|
```
|
|
|
|
## Result
|
|
|
|
<?# AsciiCast cast="canvas-image" /?>
|
|
|
|
## Manipulating images
|
|
|
|
You can take full advantage of [ImageSharp](https://github.com/SixLabors/ImageSharp)
|
|
and manipulate images directly via its [Processing API](https://docs.sixlabors.com/api/ImageSharp/SixLabors.ImageSharp.Processing.html).
|
|
|
|
```csharp
|
|
// Load an image
|
|
var image = new CanvasImage("cake.png");
|
|
image.MaxWidth(32);
|
|
|
|
// Set a sampler that will be used when scaling the image.
|
|
image.BilinearResampler();
|
|
|
|
// Mutate the image using ImageSharp
|
|
image.Mutate(ctx => ctx.Grayscale().Rotate(-45).EntropyCrop());
|
|
|
|
// Render the image to the console
|
|
AnsiConsole.Write(image);
|
|
```
|
|
|
|
## Result
|
|
|
|
<?# AsciiCast cast="canvas-image-manipulation" /?>
|
