NAME

       PDF::Builder::Resource::XObject::Image::TIFF - TIFF image support

METHODS

       $res = PDF::Builder::Resource::XObject::Image::TIFF->new($pdf, $file, $name)
       $res = PDF::Builder::Resource::XObject::Image::TIFF->new($pdf, $file)
           Returns a TIFF-image object.

           If the Graphics::TIFF package is installed, the TIFF_GT library will be used instead of the TIFF
           library. In such a case, use of the TIFF library may be forced via the "-nouseGT" flag (see Builder
           documentation for "image_tiff()").

       $mode = $tif->usesLib()
           Returns 1 if Graphics::TIFF installed and used, 0 if not installed, or -1 if installed but not used
           (-nouseGT option given to "image_tiff").

           Caution: this method can only be used after the image object has been created. It can't tell you
           whether Graphics::TIFF is available in advance of actually using it, in case you want to use some
           functionality available only in TIFF_GT. See the <PDF::Builder> LA_GT() call if you need to know in
           advance.

       $value = $tif->tiffTag($tag)
           returns the value of the internal tiff-tag.
