ImageEditor Getting Started

Prerequisites

Before adding the ImageEditor, you need to:

  1. Set up your .NET MAUI application.

  2. Download Telerik UI for .NET MAUI.

  3. Install Telerik UI for .NET MAUI.

The ImageEditor is rendered through the SkiaSharp graphics library.

Define the Control

1. When the your .NET MAUI application is set up, you are ready to add an ImageEditor control and th built-in Toolbar to your page.

<Grid RowDefinitions="Auto,*">
    <telerik:RadImageEditorToolbar ImageEditor="{x:Reference imageEditor}"/>
    <telerik:RadImageEditor x:Name="imageEditor" Grid.Row="1"/>
</Grid>
var imageEditor = new RadImageEditor();
imageEditor.Source = ImageSource.FromStream(streamFunc);

var toolbar = new RadImageEditorToolbar();
toolbar.ImageEditor = imageEditor;

var grid = new Grid();
grid.RowDefinitions.Add(new RowDefinition { Height = new GridLength(1, GridUnitType.Star) });
grid.RowDefinitions.Add(new RowDefinition { Height = new GridLength(1, GridUnitType.Auto) });
grid.Add(imageEditor, 0, 0);
grid.Add(toolbar, 0, 1);

2. Add the following namespace:

xmlns:telerik="http://schemas.telerik.com/2022/xaml/maui"

3. For the demo the image is loaded in the ImageEditor for a stream:

Func<CancellationToken, Task<Stream>> streamFunc = ct => Task.Run(() =>
{
    Assembly assembly = typeof(ImageEditorGettingStartedXaml).Assembly;
    string fileName = assembly.GetManifestResourceNames().FirstOrDefault(n => n.Contains("imageavatar.png"));
    Stream stream = assembly.GetManifestResourceStream(fileName);
    return stream;
});

this.imageEditor.Source = ImageSource.FromStream(streamFunc);

4. Register the Telerik controls through the Telerik.Maui.Controls.Compatibility.UseTelerik extension method called inside the CreateMauiApp method of the MauiProgram.cs file of your project:

using Telerik.Maui.Controls.Compatibility;

public static class MauiProgram
{
    public static MauiApp CreateMauiApp()
    {
        var builder = MauiApp.CreateBuilder();
        builder
            .UseTelerik()
            .UseMauiApp<App>()
            .ConfigureFonts(fonts =>
            {
                fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
            });

        return builder.Build();
    }
 }           

For the ImageEditor Getting Started example refer to the SDKBrowser Demo Application.
