Package standup.symbol Description

Provides classes and interfaces that handle loading and rendering of the various AAC/literacy symbol sets, e.g. Widgit Rebus and Mayer-Johnson PCS.

The underlying resources that provide access to these symbols are:

• The Widgit wordlist. This is a mapping of orthographic forms to 'conceptcodes', and of conceptcodes to pathnames that point to symbol files, usually in some vector file format.
• Various symbol sets. Currently, STANDUP supports the Widgit Rebus symbol set and the Mayer-Johnson PCS (Picture Communication Symbols) symbol set. The actual symbols themselves are not provided, and must be obtained separately. Place the PCS metafiles under a /pcs folder where the main STANDUP .jar is located. Place the Widgit Rebus SVG files under a /rebus folder where the main STANDUP .jar is located.

The SymbolManager class provides static methods for obtaining:

• symbol filenames given a Widgit conceptcode, and
• rendered bitmaps given a symbol filename.

A SymbolRenderer handles the bitmap rendering: it takes an InputStream, obtained from a symbol file (SVG for Rebus, WMF for PCS), and renders it to a BufferedImage.

A SymbolLoader handles the symbol file loading: it takes a filename (originating from a Widgit wordlist), a 'base' directory that the filename is relative to, and passes the resulting InputStream to an appropriate SymbolRenderer.
