NAME

       imgsizer - automatically splice in height and width params for HTML IMG tags

SYNOPSIS

       imgsizer [-d file] [--document-root file] [-h file] [--help file] [-n] [--no-overwrite]
                [HTMLFile] [-v file] [--version]

OPTIONS

       Display version information and exit.

       Display usage information.

       Directory where absolute image filenames (i.e, ones which contain a leading "/") may be
       found.

       -n, --no-overwwrite, .SH DESCRIPTION
              The imgsizer script automates away the tedious task of creating and updating the
              extension HEIGHT and WIDTH parameters in HTML IMG tags. These parameters help many
              browsers (including the Netscape/Mozilla family) to multi-thread image loading,
              instead of having to load images in strict sequence in order to have each one's
              dimensions available so the next can be placed. This generally allows text on the
              remainder of the page to load much faster.

       This script will try create such attributes for any IMG tag that lacks them. It will
       correct existing HEIGHT and WIDTH tags unless either contains a percent (%) sign, in which
       case the existing dimensions are presumed to be relative and left unaltered.

       This script may be called with no arguments. In this mode, it filters HTML presented on
       stdin to HTML (unaltered except for added or corrected HEIGHT and WIDTH attributes) on
       stdout. If called with file arguments, it will attempt to transform each file in place.
       Each argument file is not actually modified until the script completes a successful
       conversion pass.

       The -d <directory> option sets the DocumentRoot, where images with an absolute filename
       (i.e., ones which contain a leading "/") may be found. If none is specified, the
       DocumentRoot defaults to the current working directory.

       The -n (no-overwrite) opion prevents the program from overwriting existing width and
       height tags if both are present.

       Additional options may also be specified in the environmental variable "IMGSIZER". For
       example, to avoid typing "imgsizer -d /var/www/docs" each time imgsizer is invoked, you
       might tell sh (or one of its descendants):

       IMGSIZER="-d /var/www/docs"; export IMGSIZER

       or, if you use csh:

       setenv IMGSIZER "-d /var/www/docs"

       This script is written in Python, and thus requires a Python interpreter on the host
       system. It also requires either the identify(1) utility distributed in the open-source
       ImageMagick suite of image-display and manipulation tools, or a modern version of file(1)
       and rdjpgcom(1). These utilities are used to extract sizes from the images; imgsizer
       itself has no knowledge of graphics formats. The script will handle any image format known
       to identify(1) including PNG, GIF, JPEG, XBM, XPM, PostScript, BMP, TIFF, and anything
       else even remotely likely to show up as an inline image.

NOTE

       The -q, -l, and -m options of the 1.0 versions are gone. What they used to do has been
       made unnecessary by smarter logic.

BUGS

       The code uses regular expressions rather than true HTML/XML parsing. Some perverse but
       legal constructions, like extraneous space within quoted numeric attributes, will be
       mangled.
