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
Simple	The example shows basic container operations such as working with containers, text, generating and saving an image.
AdvancedCaptcha	Advanced work with multiple visual objects, randomization of their parameters and post-processing effects.
TwoLanguage	This example shows how to create a image with different fonts for rendering text in two languages.
WPF	This example shows how to create and display image in WPF project.
