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.
