NAME

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

METHODS

   new
           $res = PDF::Builder::Resource::XObject::Image::TIFF->new($pdf, $file, %opts)

           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()").

           Options:

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

           Remember that you need to use the Builder.pm method image_tiff in order to display a TIFF file.

   usesLib
           $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.

   tiffTag
           $value = $tif->tiffTag($tag)

           returns the value of the internal tiff-tag.
