Gesticulate

A freehand drawing tool

Download

GESTICULATE IS a simple drawing tool that was developed as a platform to try out collaborative drawing techniques. The emphasis is on simplicity and generality eschewing the complexity of more fully featured drawing apps.

Many apps strive to provide a wealth of functionality that only makes their interfaces opaque and intractable to the average user. Gesticulate is not geared towards graphic design and is intended to be used for more casual scenarios where it is required to be able to sketch an idea with some notation and then to be able to export to a variety of formats.

I should note that the original intention when the project started some years back was to leverage touch technology that did not at that time exist. It remains an unfulfilled aspiration, it is unlikely that the program can be modified for touch, but work continues apace on a reworking of the concept for touch-based devices using the JavaFX framework. [image] My project Fondu is also a touch-enabled mockup of this concept.

Work over the last 18 months has been to flesh out the syncing framework that has long been part of the code base, a project I call ‘Fidget’. To this end a proof-of-concept has been demonstrated using a web-socket end point using a NoSQL backing store and a Redis cluster to provide synchronisation. Much work is required to scale out as a deployable service, but performance seems satisfactory.

Meanwhile Gesticulate implements synchronisation only as an abstract model implemented in code, the menu is active but you will only see logging from the terminal.

Features

Sketch

The app provides vector shapes and a curve-fitted sketching tool which allow grouping of shapes, arrow lines and other strokes including dotted, double and railway-tracks.

Rich Text

Formatted text is supported including bold, italic, underlined and three fonts. Text boxes are single-lined but provide input methods and may be oriented at any angle for easy labels.

Images

Import bitmap images in the most common formats to the drawing, scale them and rotate them and use the drawing tool to highlight them, adding arrows and text comments.

Snapshot

There is a screenshot button at the top-right which captures a snapshot of the current drawing to the Desktop. Capture a series of screenshots as the starting point for a presentation.

Maps

Mapping viewports based on an image that update from a variety of Open Streetmap and Bing Maps sources, maps are easily resized and highlighted with the drawing tools.

Export

Easily export a clean scalable vector (SVG) rendering of the current drawing for resolution independent output and export a bitmap version (PNG) for use in other applications.
