pivi v0.1.5
Pivi
Pivi (short for Pipeviewer) is a tool that simplifies visualization tasks. It has a simple stream based input format.
Installation
You need Cairo to create the images. We use node-canvas to create the images they have an installation guide on their project page.
Then you simply run:
npm install -g pivi
Or if you want to use pivi in your project you can use
npm install pivi
Example
The following program generates a zigzag line and outputs it as a PNG image.
echo "polyline (0 0) (100 100) (100 0) (0 100)" | pivi
Supported Commands
All points can be written as a tupel or you can simply omit all commas or brackets.
point 1 2
points (1 2) (3 3)
line (0, 0) (20 30)
lines ((0, 0) (20 40)) ((0,0) (40,20))
(draws one line for each pair of points)polyline 0 0 ... 100 0

You can try ImageMagick's convert. You can pass arguments to it that function similar to our commands. More here
