This is the command imgsizep that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
imgsize - read the dimensions of an image in several popular formats
imgsize [ -r | -a | -f fmt ] file [ file ... ]
No-brainer to size an image supplied on the command-line. All the real work is done in
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
% imgsize dot.gif dash.gif
dot.gif: width="16" height="16"
dash.gif: width="32" height="8"
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):
Return "raw" format data. Just the numbers separated by a single space.
Return a Perl-style list of attributes suitable for passing to the "img()" method of
the CGI module (see CGI).
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.
imgsize always exits
