NAME¶
imgsize - read the dimensions of an image in several popular formats
USAGE¶
imgsize [ -r | -a | -f fmt ] file [ file ... ]
DESCRIPTION¶
No-brainer to size an image supplied on the command-line. All the real work is
done in Image::Size.
REQUIRED ARGUMENTS¶
imgsize expects file names on the command-line. If more than one file is
provided, the file name will be included in the output:
% imgsize dot.gif
width="16" height="16"
% imgsize dot.gif dash.gif
dot.gif: width="16" height="16"
dash.gif: width="32" height="8"
OPTIONS¶
By default, the width and height are returned as attributes for an IMG tag in
HTML, essentially "width="40"
height="30"" or similar. The following options may be
used to return alternate formats (all report width first, then height):
- "-r"
- Return "raw" format data. Just the numbers separated by a single
space.
- "-a"
- Return a Perl-style list of attributes suitable for passing to the
"img()" method of the CGI module (see
CGI).
- "-f" fmt
- Pass the string specified in fmt to
"sprintf" and thus use it to format the
results to your taste. "sprintf" will be
passed two numbers, so any other formatting directives will be lost. The
numbers are passed as width first, then height.
EXIT STATUS¶
imgsize always exits
