A pure Go library for 2D graphics rendering with a simple and comprehensive API.
gg is a 2D graphics library written in pure Go for programmatically creating images, drawings, and visualizations. It provides a straightforward API for common rendering tasks like drawing primitives, text, and applying transformations, enabling developers to generate graphics without external dependencies.
Go developers who need to programmatically generate images, charts, diagrams, or visualizations directly within their Go applications, such as for data visualization tools, report generation, or simple game graphics.
Developers choose gg for its simplicity and ease of use, offering a clean, minimal API that covers essential 2D graphics operations without unnecessary complexity, all while being a pure Go library with no external dependencies.

The library provides straightforward functions like DrawCircle and SetRGB, making it easy to start drawing basic shapes with minimal code, as demonstrated in the Hello Circle example.
As a pure Go implementation, gg avoids external C libraries or tools, simplifying installation and cross-compilation for various platforms, as highlighted in the project description.
Includes features like word wrapping, anchoring, and multiline measurement, allowing for complex text layout without additional libraries, as shown in the Text Functions section.
Supports rotations, scales, and shears about arbitrary points with functions like RotateAbout, enabling precise control over graphic elements, as detailed in the Transformation Functions.
The library is designed for static image generation and lacks built-in functions for creating animations or handling dynamic graphics over time, limiting use to single-frame outputs.
Rendering is done on the CPU, which may lead to performance bottlenecks when generating very large or complex images compared to GPU-accelerated alternatives, as there's no mention of hardware acceleration.
Primarily focused on PNG output with SavePNG, with no native support for other common formats like JPEG or GIF without integrating additional image processing libraries.
