This is an extremely powerful tool for creating procedural images from scratch. You can use it to generate captchas, datasets to train neural networks or unique game mechanics - in other words, for anything your imagination can do

Features

• Multi-container system for processing visual entities without the need for complete redrawing
• Full randomizability of all properties of all entities - from color and font size to the strength of the distortion/blur/any effects
• A huge number of effects for post-processing images - from color correction and geometric distortion, to sharpness and pixelation modifiers
• Ability to write code with confinient fluent interface and the classic object-oriented approach
• Full cross-platform without being tied to any specific operating system

Getting started

For detailed illustrated code examples, we recommend you go to the Wiki section. However, here is a sample:

var fontFamily = new FontCollection()
    .AddSystemFonts()
    .GetByCulture(CultureInfo.CurrentCulture)
    .First();
    
Size containerSize = new(512, 256);

Container container = new(containerSize)
    .WithContainer(
        new Container(containerSize)
            .WithBackground(Color.White)
            .WithVisual(
                new Text()
                    .WithPoint(new Point(256,128))
                    .WithFontSize(100)
                    .WithRandomizedContent(content => {
                        content.WithLength(5);
                        content.WithCharactersSet(StringProperty.asciiUpperCase);
                    })
                    .WithRandomizedBrush(10)
                    .WithFontFamily(fontFamily)
                    .WithType(ExNihilo.Utils.VisualType.Filled)
            )
    );

new ImageSaver(
    new ImageGenerator(container)
        .WithSeedsCount(3)
        .Generate())
.WithOutputPath("./")
.CreateFolder("Results")
.Save();

Example projects

You can always find several test projects with detailed code explanations in a directory /examples:

Project	Description	Result
