diku-dk/diku-canvas

DIKU-Canvas is a 2D graphics library for F\# that provides tools for rendering immutable shapes, handling user input, and managing fonts and colors. It leverages SDL2 and ImageSharp to support window-based rendering, file export, and interactive animations. The system includes comprehensive examples demonstrating low-level drawing operations, collision detection, and image processing capabilities.

New F\# script examples have been added to the low-level examples directory to demonstrate core canvas capabilities. These include a moving box animation with timer-driven state updates, a paths demo showcasing drawing of lines, text, rectangles, and arcs, a color-box example that cycles palettes via keyboard input and saves output to a file, and a text rendering demo. These scripts serve as interactive references for using the DIKU.Canvas low-level API.

This change introduces the DIKU-Canvas library, a functional 2D graphics toolkit for F\# built on SDL2 and ImageSharp. It provides a \PrimitiveTree\ data structure for composing immutable shapes (rectangles, arcs, text, etc.) with transformations like translation, rotation, and scaling. The library exposes a public API for rendering to windows or files, handling user input (keyboard, mouse, timers) via an interactive mode, and managing colors and fonts. It also includes low-level SDL wrappers and a \.gitignore\ file to manage build artifacts and dependencies.

The examples directory now includes a comprehensive set of F\# scripts demonstrating the DIKU.Canvas 2.0 API, covering basic rendering, interactive animation, mouse and keyboard input handling, and file export. New demos include an animated GIF generator, a mini-game with collision detection, and a color test, alongside updated versions of existing examples like movingBox and spiral. Additionally, shell scripts are provided to manage local NuGet references and update package versions across the example files.

The notes directory has been refreshed with a new set of examples. Several files have been converted to use the SixLabors.ImageSharp library for image processing, including demonstrations of drawing text along paths, applying rounded corners to images, and generating various geometric shapes. Additionally, new test scripts for the DIKU.Canvas library (versions 1.0.2, 2.0.0-alpha3, and 2.0.0-alpha6) have been added to cover low-level and high-level canvas operations, while older, non-portable examples from the legacy ImgUtil system remain in the directory.

The DIKU.Canvas library has been updated to version 2.0.4, targeting the .NET 6.0 framework. This release includes updates to key graphics dependencies: SixLabors.Fonts to 2.0.4, SixLabors.ImageSharp to 3.1.4, and SixLabors.ImageSharp.Drawing to 2.1.3, ensuring compatibility with the latest image processing and font rendering capabilities.
