Crate asvgard 

Asvgard

asvgard is a lightweight, dependency-free (mostly) graphics rendering library written in Rust. It provides a unified interface for loading, decoding, and rasterizing various image formats including SVG, PNG, and TGA.

Features

• SVG Support: Custom-built XML parser and rasterizer supporting paths, shapes, strokes, and fills.
• PNG Support: From-scratch implementation of DEFLATE (zlib) decompression and filtering.
• TGA Support: Native support for uncompressed and RLE-compressed TGA files.
• No External Image Crates: All decoding logic is implemented internally for educational and lightweight purposes.

Usage

use asvgard::prelude::*;

// Load an image from bytes (detects format automatically)
let data = include_bytes!("../test.png");
let width = 800;
let height = 600;

match load_image(data, width, height) {
    Ok(buffer) => {
        println!("Image loaded! Buffer size: {}", buffer.len());
        // buffer contains ARGB u32 pixels
    }
    Err(e) => eprintln!("Failed to load image: {}", e),
}
