# SVG for C++

[![Build Status](https://travis-ci.org/vincentlaucsb/svg.svg?branch=master)](https://travis-ci.org/vincentlaucsb/svg) [![codecov](https://codecov.io/gh/vincentlaucsb/svg/branch/master/graph/badge.svg)](https://codecov.io/gh/vincentlaucsb/svg)

## Purpose

This a header-only library for generating SVG files from a simple C++ interface. It can also perform non-trivial tasks such as calculating a bounding box for an SVG's elements, or merging several graphics together.

## Basic Usage

```

#include "svg.hpp"

#include 

int main() {

    SVG::SVG root;

    // Basic CSS support

    root.style("circle").set_attr("fill", "#000000")

        .set_attr("stroke", "#000000");

    root.style("rect#my_rectangle").set_attr("fill", "red");

    // Method 1 of adding elements - add_child<>()

    auto shapes = root.add_child();

    auto rect = shapes->add_child("my_rectangle");

    // Method 2 of adding elements - operator<<

    *shapes << SVG::Circle(-100, -100, 100) << SVG::Circle(100, 100, 100);

    // Reference elements by id, tag, class name, etc...

    root.get_element_by_id("my_rectangle")

        ->set_attr("x", 20).set_attr("y", 20)

        .set_attr("width", 40).set_attr("height", 40);

    std::cout << "There are " << root.get_children().size() <<

        " circles." << std::endl;

    // Automatically scale width and height to fit elements

    root.autoscale();

    // Output our drawing

    std::ofstream outfile("my_drawing.svg");

    outfile << std::string(root);

}

```

### Output

```

	

		<![CDATA[

			circle {

				fill: #000000;

				stroke: #000000;

			}

			rect#my_rectangle {

				fill: red;

			}

		]]>

## Simple Animations

This package supports creating basic animations via CSS keyframes via the frame_animate() function.
