pyro's Introduction

Pyro graphics library

Graphics library used for generation of images

This library is made for use in my own artistic practise, and comes with no guarnatees of quality. It is heavly influenced by Processing, but at the time has no functionality for real time graphics and no 3D graphics functionality.

It's primary use is for generating still images with 2D graphics, and functionality is implemented as I need it.

The state of the whole thing is not really userfriendly at the moment, but hopefully that will improve in the future.

Dependencies

Library	Version	License
Cairo	1.14.x	LGPL/MPL
Freetype 2	2.10.1	Freetype project License

Building

Using Meson

meson build
ninja -C build

Install

ninja -C build install

Run tests

ninja -C build test

Build an example

make ./examples/graphics/piechart

Usage

A very simple example

#include <pyro/pyro.h>

using namespace Pyro

int main(int argc, char **argv) {
    size(1920, 1080);
    translate(width / 2, height / 2);
    ellipse(0, 0, 50, 50);
    save("test.png");
}

Save as mytest.cpp, do a make mytest, and you should have an executable.

Tests

Some tests have been implemented using Catch2

Installing

If you run make install at the moment, it is just doing some dumb stuff to get it installed on Mac. You can then compile and link a file with something like: g++ -MMD -MP -lpyro -std=c++17 somefile.cpp

Todo

Write a better install target
Make a configure script?
Write some abstraction to make possible different backends for rendering
