PDF::Builder::Resource::XObject::Image::TIFF \- TIFF image support
.SH METHODS

.SS new
.IX Subsection "new"
.Vb 1
\&    $res = PDF::Builder::Resource::XObject::Image::TIFF\->new($pdf, $file, %opts)
.Ve
.Sp
.RS 4
Returns a TIFF-image object.
.Sp
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 \f(CW\*(C`nouseGT\*(C'\fR flag (see Builder documentation for \f(CWimage_tiff()\fR).
.Sp
Options:
.IP "'name' => 'string'" 4
.IX Item "'name' => 'string'"
This is the name you can give for the TIFF image object. The default is Ixnnnn.
.RE
.RS 4
.Sp
Remember that you need to use the Builder.pm method image_tiff in order to
display a TIFF file.

.SS usesLib
.IX Subsection "usesLib"
.Vb 1
\&    $mode = $tif\->usesLib()
.Ve
.Sp
.RS 4
Returns 1 if Graphics::TIFF installed and used, 0 if not installed, or \-1 if
installed but not used (nouseGT option given to \f(CW\*(C`image_tiff\*(C'\fR).
.Sp
\&\fBCaution:\fR this method can only be used \fIafter\fR 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> \fBLA_GT()\fR call if you
need to know in advance.
