$image->rectangle (0,0, 99,99, 'white');

CLASS HIERARCHY

Image::Base::GD is a subclass of Image::Base,

Image::Base
  Image::Base::GD

DESCRIPTION

Image::Base::GD extends Image::Base to create or update PNG format image files using the GD module and library.

Colour names are taken from the GD::Simple color_table, plus hex "#RRGGBB". The special colour "None" means transparent. Colours are allocated when first used.

FUNCTIONS

$image = Image::Base::GD->new (key=>value,...)

Create and return a new image object. A new image can be start with -width and -height,

$image = Image::Base::GD->new (-width => 200, -height => 100);

Or an existing file can be read,

$image = Image::Base::GD->new (-file => '/some/filename.png');

Or a GD::Image object can be used,

$image = Image::Base::GD->new (-gd => $gdimageobject);

ATTRIBUTES

-width (integer, read-only)

-height (integer, read-only)

The size of a GD image cannot be changed once created.

-ncolours (integer, read-only)

The number of colours allocated in the palette, or undef on a truecolor GD (since it doesn't have a palette).

This colour count is similar to the -ncolours of Image::Xpm.

-zlib_compression (integer 0-9 or -1)

The amount of data compression to apply when saving. The value is Zlib style 0 for no compression up to 9 for maximum effort. -1 means Zlib's default level.

-gd

The underlying GD::Image object.
