imgsize - Man Page

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 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"


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).

-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
