23 LW-GT Reference Entries

This chapter provides reference entries for the symbols exported from the lw-gt package. This package is for the Graphic Tools, which are interfaces which use Graphics Ports and CAPI. These contain the drawing objects, which add a mechanism to creates a hierarchy of drawing, when a "drawing" is (typically) a simple Graphics Ports drawing operation. The hierarchy specifies the geometry of each node in the hierarchy, so the whole group drawings can be manipulated as a single object.

To use Graphic Tools, you first need to load the module "graphic-tools", like this:

(require "graphic-tools")

See 14 Graphic Tools drawing objects for an overview of Graphic Tools.

See 1 Introduction to the CAPI for an overview of CAPI, and 13 Drawing - Graphics Ports for more information on Graphics Ports.
