NAME
PDF::Builder::Resource::XObject::Image::TIFF - TIFF image support
Inherits from PDF::Builder::Resource::XObject::Image
METHODS
new
$res
= PDF::Builder::Resource::XObject::Image::TIFF->new(
,
$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:
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.
