Library for rendering images and videos directly using C and the NetPBM image format

Compile repo:

make 
./render

or 
g++ -o render main.cpp Artwork/Color.h Artwork/Artwork.h Artwork/Artwork.c
./render

Include header:

#include "Artwork/Artwork.h"

Create artwork and set values:

Artwork art = newArt(400, 400);

Dont forget to free afterwards to avoid memory leaks!

freeArt(art);

Set color scheme with stroke, fill and stroke width:

art.strokeColor = Color { 255, 0, 0 };
art.strokeWidth = 5;

art.fillColor = Color { 200, 200, 200 };

Set individual pixel

setPixel(art, <x>, <y>, Color {255, 255, 255});

Draw line (color determined by stroke color):

drawLine(art, <x0>, <y0>, <x1>, <y1>);

Draw rect:

drawRect(art, <top-left x>, <top-left y>, <width>, <height>);

Draw circle:

drawCircle(art, <x>, <y>, <radius>);

Draw ellipse:

drawEllipse(art, <x>, <y>, <x-radius>, <y-radius>);

Clear artwork / fill it entirely_

clear(art, Color { 0, 0, 0 });

Save as a single image:

char filename[] = "nicePic.ppm";
saveArt(art, filename);

Pipe it out (necessary for video creation):

pipeArtTo(art, stdout);

Pipe it to VLC:

./ExecutableNameHere | ppmtoy4m -F60:1 | vlc -

Or render the complete video:

./ExecutableNameHere | ffmpeg -i pipe:0 -c:v libx264rgb VideoName.avi

The SFML_Artwork class is essentially a C++ wrapper for the standard rendering. It enables you to create Artworks from sf::Image objects, the entire window for example.

#include "SFML_Artwork/SFML_Artwork.h"

Create your window and rendering:

RenderWindow window(VideoMode(800, 800), "Rendering");
Rendering* rendering = createRendering(800, 800);

Texture texture;
Image image;
Vector2u windowsize;

Save your window as an image:

windowsize = window.getSize();
texture.create(windowsize.x, windowsize.y);
texture.update(window);
image = texture.copyToImage();
Artwork art = SFML_Artwork::fromImage(image);
saveArt(art);
