# NanoVG
Julia bindings for the [NanoVG](https://github.com/memononen/nanovg) drawing library.
> NanoVG is small antialiased vector graphics rendering library for OpenGL.
> It has lean API modeled after HTML5 canvas API. It is aimed to be a practical and fun toolset for building scalable user interfaces and visualizations.
## Screenshot
## Installation
NanoVG is a
Julia Language
package. To install NanoVG,
open
Julia's interactive session (known as REPL) and press ] key in the REPL to use the package mode, then type the following command:
```shell
pkg> add https://github.com/dylanxyz/NanoVG.jl
```
> Note that NanoVG is not yet at the public registry,
> installation is done directly from this repo.
## Documentation
In progress...
## Basic Example
```julia
using GLFW
using NanoVG
using ModernGL
function main()
title = "NanoVG Basic Example"
width = 800
height = 600
window = GLFW.CreateWindow(width, height, title)
@assert window.handle != C_NULL "Could not create a GLFW window 😢"
GLFW.MakeContextCurrent(window)
# Create the NanoVG context with the GL3 implementation
NanoVG.create(NanoVG.GL3, antialiasing=true)
while true
if GLFW.WindowShouldClose(window) break end
# get the framebuffer size
width, height = GLFW.GetFramebufferSize(window)
# get the window size
winWidth, winHeight = GLFW.GetWindowSize(window)
# dpr = device pixel ratio
dpr = width / winWidth
# set the viewport
glViewport(0, 0, width, height)
# create a new frame
NanoVG.frame(winWidth, winHeight, dpr)
# drawing functions should be called here
# set the fill color
fillcolor(rgb(128, 32, 56))
# draw a filled circle at the center of the screen
circle(width/2, height/2, 128, :fill)
# render the frame to the screen
NanoVG.render()
GLFW.SwapBuffers(window)
GLFW.PollEvents()
end
NanoVG.dispose()
GLFW.DestroyWindow(window)
end
main()
```
