The Magick scripting language (MSL) will primarily benefit those
that want to accomplish custom image processing tasks but do not
wish to program, or those that do not have access to a Perl
interpreter or a compiler. The interpreter is called conjure and
here is an example script:
All operations will closely follow the key/value pairs defined
in PerlMagick, unless otherwise noted.
Conjure is in the early stages of development
as of April 2002.
This early announcement is to allow ImageMagick users to
contribute ideas early in the process so when the scripting
language is released it will be useful/stable from the get-go! If
you want to contribute suggestions about the Magick scripting
language (MSL), post them to the ImageMagick tools list at
imagemagick-tools @ lists.sourceforge.net.
Options are processed in command line order. Any option you
specify on the command line remains in effect until it is
explicitly changed by specifying the option again with a different
effect, or if it is changed by a statement in the scripting
language.
You can define your own keyword/value pairs on the command line.
The script can then use this information when setting values by
including %[keyword] in the string. For example, if you included
"-dimensions 400x400" on the command line, as illustrated above,
then any string containing "%[dimensions]" would have 400x400
substituted. The "%[string]" can be used either an entire string,
such as geometry="%[dimensions]" or as a part of a string such as
filename="%[basename].png".
The keyword can be any string except for the following reserved
strings (in any upper, lower, or mixed case variant):
debug, help, and
verbose, whose usage is described below.
The value can be any string. If either the keyword or the value
contains white space or any symbols that have special meanings to
your shell such as "#", "|", or "%", enclose the string in
quotation marks or use "\" to escape the white space and special
symbols.
Keywords and values are case dependent. "Key", "key", and "KEY"
would be three different keywords.
For a more detailed description of each option, see Options,
above.
ImageMagick(1).
The Magick Scripting Language (MSL) presently defines the
following elements and their attributes:
<image>
Define a new image object. </image>
destroys it. Because of this, if you wish to reference multiple
"subimages" (aka pages or layers), you can embed one
image element inside of another. For example:
Define a new group of image objects. By default, images are
only valid for the life of their
<image>element.
<image> -- creates the image
..... -- do stuff with it
</image> -- dispose of the image
However, in a group, all images in that group will stay around
for the life of the group:
<group> -- start a group
<image> -- create an image
.... -- do stuff
</image> -- NOOP
<image> -- create another image
.... -- do more stuff
</image> -- NOOP
<write filename="image.mng" /> -- output
</group> -- dispose of both images
Write the image(s) to disk, either as a single multiple-image
file or multiple ones if necessary.
<write filename=image.tiff" />
<get>
Get any attribute recognized by PerlMagick's GetAttribute() and
stores it as an image attribute for later use. Currently only
width and height are supported.
<get width="base-width" height="base-height" />
<print output="Image size is %[base-width]x%[base-height].\n" />
<set>
background, bordercolor, clip-mask, colorspace, density,
magick, mattecolor, opacity. Set an attribute recognized by
PerlMagick's GetAttribute().
