Overview

Minimal, independent library for basic scientific diagram generation. Portable, does not depend on OS or any third-party libraries.

Features

Library provided two levels of abstraction:

• pixel canvas
• drawing primitives: lines, rectangles, circles, ellipses, b-splines, triangles, flood filling

Output: currently only PPM files (batch generation).

Samples

1. Voronoi

Pixel map depicting Voronoi diagram.

See apps/voronoi.cpp

Sample output:

2. Mandelbrot

Pixel map image for selected window.

See apps/mandelbrot.cpp

Sample output:

3. 3D Chart

Very basic 3D chart using colorful lines.

See apps/chart3d.cpp

Sample output:

4. Primitives

Demonstration of included primitive shape support.

See apps/draw_primitives.cpp

Sample output:

Building from console

1. Create new build folder

    mkdir _build
    cd _build
   

2. Prepare makefile

    cmake .. 
   

3. make sample applications

    make
   

4. to run just built example - voronoi - just enter:

    ./voronoi
   

API

Currently there is no single include file which can be used to use the library. So you need to include individual header files in order to use specific features.

Source directories:

• base: data structures
• utils: internal utility functions for various purposes
• pixels: pixel-level API
• images: API for images
  • PixelImage: image abstraction
  • RgbImage: in-memory image container
  • PPM image writer & loader
• painters: API for drawing graphic primitives (lines, circles, etc.)
