PDF::Builder::Resource::XObject::Image::TIFF - TIFF image support
- $res = PDF::Builder::Resource::XObject::Image::TIFF->new($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.
