PDF::API2::Resource::ColorSpace::Indexed::ACTFile

METHODS

Top

$cs = PDF::API2::Resource::ColorSpace::Indexed::ACTFile->new $pdf, $actfile

Returns a new colorspace object created from an adobe color table file (ACT/8BCT). See Adobe Photoshop® 6.0 -- File Formats Specification Version 6.0 Release 2, November 2000 for details.

$cs = PDF::API2::Resource::ColorSpace::Indexed->new_api $api, $name

Returns a indexed color-space object. This method is different from 'new' that it needs an PDF::API2-object rather than a Text::PDF::File-object.
