PixelFlut.jl

Julia implementation of the pixelflut protocol.

Provides functions for client and server applications.

A pixelflut server is provided as PixelFlut.Server.

A viewer client is provided as PixelFlut.Viewer. This client connects to a pixelflut server and copies it's contents into a framebuffer.

Usage

Server example:

julia -t 8 -e "using PixelFlut; PixelFlut.run(PixelFlut.Server((512, 512))"

Vary thread count and canvas size as needed.

Viewer example:

julia -t 8 -e "using PixelFlut; PixelFlut.run(PixelFlut.Viewer(\"127.0.0.1\", 1337))"

Adapt as needed.

PixelFlut Protocol

• HELP\n: Show a help message
• SIZE\n Return (width, height) of canvas
• PX {x} {y}\n: Return RRGGBB of pixel at (x, y) as PX {x} {y} {RRGGBB}\n
• PX {x} {y} RRGGBB\n: Set pixel at (x, y) to RRGGBB
• PX {x} {y} RRGGBBAA\n: Set pixel at (x, y) to RRGGBBAA

Usage

Connect to server and send the respective command. For example the following sets the pixel at (1, 2) to red:

echo "PX 1 2 FF0000\n" | netcat 127.0.0.1 1337
