imgsize

IMGSIZE(1p)						User Contributed Perl Documentation					       IMGSIZE(1p)

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
