NAME

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

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).

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

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

       -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.
