Implements default import method for modules
The Exporter module implements an import method which allows a module to export functions and variables to its users' name spaces. Many modules use Exporter rather than implementing their own import method because Exporter provides a highly flexible interface, with an implementation optimized for the common case.

This package is the shared library for perl.
GD::Barcode is a subclass of GD and allows you to create barcode image with GD.
This pragma allows you to declare constants at compile-time. When a constant is used in an expression, Perl replaces it with its value at compile time, and may then optimize the expression further. In particular, any code in an "if (CONSTANT)" block will be optimized away if the constant is false.
A perl5 interface to Thomas Boutell's gd library
This is a autoloadable interface module for libgd, a popular library for creating and manipulating PNG files. With this library you can create PNG images on the fly or modify existing files. Features include: a. lines, polygons, rectangles and arcs, both filled and unfilled b. flood fills c. the use of arbitrary images as brushes and as tiled fill patterns d. line styling (dashed lines and the like) e. horizontal and vertical text rendering f. support for transparency and interlacing g. support for TrueType font rendering, via libfreetype. h. support for spline curves, via GD::Polyline i. support for symbolic font names, such as "helvetica:italic" j. support for symbolic color names, such as "green", via GD::Simple k. produces output in png, gif, jpeg and xbm format l. produces output in svg format via GD::SVG.
Establish an ISA relationship with base classes at compile time
Allows you to both load one or more modules, while setting up inheritance from those modules at the same time.
