PDF::Builder::Resource::XObject::Image::TIFF - TIFF image support
$res = PDF::Builder::Resource::XObject::Image::TIFF->new($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()).
nouseGT
image_tiff()
Options:
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.
$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).
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.
Useful Tags:
