NAME

       PDF::Builder::Resource::XObject::Image::GIF - support routines for GIF image library. Inherits from
       PDF::Builder::Resource::XObject::Image

   History
       GIF89a Specification: https://www.w3.org/Graphics/GIF/spec-gif89a.txt

       A fairly thorough description of the GIF format may be found in
       <http://giflib.sourceforge.net/whatsinagif/bits_and_bytes.html>.

       Code originally from PDF::Create, PDF::Image::GIFImage - GIF image support Author: Michael Gross

Supported Formats

       GIF87a and GIF89a headers are supported. The Image block (x2C) is supported.

       The Graphic Control Extension block (x21 + xF9) is supported for transparency control. Animation is not
       supported.

       The Comment Extension block (x21 + xFE), Plain Text Extension block (x21 + x01), and Application
       Extension block (x21 + xFF) are read, but ignored. Any other block or Extension block will be flagged as
       an error.

       If given, Local Color Tables are read and used, supposedly permitting more than 256 colors to be used
       overall in the image (despite the 8 bit color table depth).

   Options
       notrans
           When  defined  and  not 0, "notrans" suppresses the use of transparency if such is defined in the GIF
           file.

       name => 'string'
           This is the name you can give for the GIF image object. The default is Gxnnnn.

       multi
           When defined and not 0, "multi" continues processing past the end of the first Image Block.  The  old
           behavior, which is now the default, is to stop processing at the end of the first Image Block.

METHODS

   new
            PDF::Builder::Resource::XObject::Image::GIF->new()
