.SH NAME
imgsize \- read the dimensions of an image in several popular formats
.SH USAGE
.IX Header "USAGE"
.Vb 1
\& imgsize [ \-r | \-a | \-f fmt ] file [ file ... ]
.Ve
.SH DESCRIPTION
.IX Header "DESCRIPTION"
No-brainer to size an image supplied on the command-line. All the real
work is done in Image::Size.
.SH "REQUIRED ARGUMENTS"
.IX Header "REQUIRED ARGUMENTS"
\&\fBimgsize\fR expects file names on the command-line. If more than one file is
provided, the file name will be included in the output:
.PP
.Vb 5
\&    % imgsize dot.gif
\&    width="16" height="16"
\&    % imgsize dot.gif dash.gif
\&    dot.gif: width="16" height="16"
\&    dash.gif: width="32" height="8"
.Ve
.SH OPTIONS
.IX Header "OPTIONS"
By default, the width and height are returned as attributes for an IMG tag in
HTML, essentially \f(CW\*(C`width="40" height="30"\*(C'\fR or similar. The following options
may be used to return alternate formats (all report width first, then height):
.ie n .IP """\-r""" 4
.el .IP \f(CW\-r\fR 4
.IX Item "-r"
Return "raw" format data. Just the numbers separated by a single space.
.ie n .IP """\-a""" 4
.el .IP \f(CW\-a\fR 4
.IX Item "-a"
Return a Perl-style list of attributes suitable for passing to the \f(CWimg()\fR
method of the CGI module (see CGI).
.ie n .IP """\-f"" \fBfmt\fR" 4
.el .IP "\f(CW\-f\fR \fBfmt\fR" 4
.IX Item "-f fmt"
Pass the string specified in \fIfmt\fR to \f(CW\*(C`sprintf\*(C'\fR and thus use it to format
the results to your taste. \f(CW\*(C`sprintf\*(C'\fR will be passed two numbers, so any
other formatting directives will be lost. The numbers are passed as width
first, then height.
.SH "EXIT STATUS"
.IX Header "EXIT STATUS"
\&\fBimgsize\fR always exits
.SH BUGS
.IX Header "BUGS"
Please report any bugs or feature requests to
\&\f(CW\*(C`bug\-image\-size at rt.cpan.org\*(C'\fR, or through the web interface at
<http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Image\-Size>. I will be
notified, and then you'll automatically be notified of progress on
your bug as I make changes.
