Install Canvas

A Raspberry Pi can easily serve 4&nbspK high definition images (3840 x 2160 pixels) to a TV screen or a computer monitor. The system is aimed to remain lightweight. It uses the framebuffer to display the images and, as such, doesn't require the X Window System to be installed.

The installation instructions are provided for raspbian on a Raspberry Pi.

Base installation

At first, install the raspbian console operating system.

Set the framebuffer resolution to match the monitor's.

Install the framebuffer image viewer together with the graphic libraries for image transformation and display.

The system is to be controlled via xPL. Install:

• the hub
• the clock ticker
• the dawn/dusk messenger

Next, install a web server for the control of the display over web pages.
