PROGRAM:
NAME
xlito - Append/Delete/Show a Trailing Option string in a file.
(XLoadImageTrailingOptions)
SYNOPSIS
xlito [option] [string] files ...
DESCRIPTION
xlito (XLoadImageTrailingOptions) is a utility that provides a file format independent way
of marking image files with the appropriate options to display correctly. It does this by
appending to a file, a string specified by the user. The string is marked with some magic
numbers so that it can be extracted by a program that knows what to look for. Since almost
all image files have some sort of image dimension information in the file, the programs
that load or manipulate these files generally do not look beyond the point at which they
have read the complete image, so trailing information is safely be hidden. If appending
this information causes trouble with other utilities, it can simply be deleted.
Appropriate version of xloadimage (ie. xli 1.00) will recognise these trailing options at
the end of the image files, and will treat the embedded string as if it were a sequence of
command line Image Options. Any Global Options will be ignored, and unlike command line
image Options, Trailing Options are never propagated to other images.
Old versions of xloadimage (3.01 or less) can be made forward compatible by using the -x
option to pull the trailing options out of the image files, and put them on the command
line where xloadimage can see them.
OPTIONS
The default behavior is to display the trailing option strings (if any) of the files on
the argument line. The following options change the behavior of xlito:
-c option_string file_name ...
This adds or changes the embedded string to option_string. The string will have
to be quoted if it is composed of more than one word.
-d file_name ...
Delete any embedded trailing option strings in the given files.
-x file_name ...
Process the files and create a command line string suitable for use by xloadimage.
Arguments starting with - are echoed, arguments not starting with - are treated as
files and any trailing options strings are echoed followed by the file name. The
xloadimage option -name is treated correctly.
EXAMPLES
If fred.gif has the wrong aspect ratio, then it might need viewing with the xloadimage
options:
xloadimage -yzoom 130 fred.gif
This option can then be appended to the file by:
xlito -c "-yzoom 130" fred.gif
and from then on some new versions of xloadimage will get the appropriate options from the
image file itself. Old versions of xloadimage can be made to work by using:
xloadimage `xlito -x fred.gif`
This can be made transparent by using a script containing something like:
xloadimage `xlito -x $∗`
The script could be called xli for instance.
The options can be deleted with:
xlito -d fred.gif
