This is a template for a poetry interface that uses the touchscreen's pinch gesture as its method of moving between texts. On a non-touchscreen device, scrolling with the mousewheel or trackpad achieves the same effect. This code provide the basis for a Pinch-zoom reading interface and was also used to create the digital version of my poem sequence '10x'

Content

This code repository contains a template for the interface, contained in the 'index.html' and 'pinch-zoom-adapted-from-bigpicture.js' files. The JS and CSS files labelled 'bigpicture' are from the Big Picture library, which is a framework for creating infinite zooming and panning interfaces.

Third-party software

  • Big Picture - used as the main basis for the interface, adapted to restrict the direction of zooming and panning to suit the display of the poem. Used under the MIT license. A copy of the license is available at: https://opensource.org/licenses/MIT

  • Hammer.js - used to enable touchscreen functionality. Used under the MIT license.
