NAME
throttleimg - Script to automatically split images into multiple sizes
SYNOPSIS
throttleimg [options] file1 ...
DESCRIPTION
throttleimg is a script distributed with Apache::Throttle. It can be used to automatically create a set of different size images from one large image and store them in a format that Apache::Throttle will understand.
The file (or files) you specify will be replaced with a directory of the same name. The original file will be saved in this directory as "Z-<original name>". throttleimg will then create a set of images (the number of images can be set with the --steps option and defaults to 3) that look like the original image but have a lower quality.
Theoretically, this script can be used to automatically convert all of your existing images to be controlled by Apache::Throttle. You might try a command like:
find /home/httpd -name '*.gif' -o -name '*.jpg' | \
xargs throttleimg --time=5 --steps=3OPTIONS
- --help, -h
-
Shows usage information.
- --quiet, -q
-
This option tells throttleimg not to output any status messages to STDOUT. Only warnings and errors are printed to STDERR.
- --time=<seconds>, -t=<seconds>
-
This is the time in seconds that the image should take to load. It is used to determine the speed required to download each image. This can be a floating point number.
- --steps=<images>, -s=<seconds>
-
This option tells throttleimg how many different images to make.
- --same-size
-
This option tells throttleimg not to change the size of the images created. You probably want to use this if you're using these images inline in a HTML page and don't plan to use WIDTH and HEIGHT arguments in the <IMG> tag.
- --same-colors
-
This option tells throttleimg not to change the number of colors in the images created. It is the default value for JPEGs.
- --same-quality
-
This option tells throttleimg not to change the quality of the images created. It is the default value for GIFs.
- --undo, -u
-
This option causes throttleimg to do the opposite of what it normally does. Instead of turning an image into a directory of different images, it removes all of the images created by a previous call to throttleimg and replaces the directory with the original image.
