- % Conjure interprets and executes scripts in the Magick Scripting Language
- % (MSL). 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:
- %
- % <?xml version="1.0" encoding="UTF-8"?>
- % <image size="400x400" >
- % <read filename="image.gif" />
- % <get width="base-width" height="base-height" />
- % <resize geometry="%[dimensions]" />
- % <get width="width" height="height" />
- % <print output="Image sized from %[base-width]x%[base-height]
- % to %[width]x%[height].\n" />
- % <write filename="image.png" />
- % </image>

- % ConjureImageCommand() describes the format and characteristics of one or
- % more image files. It will also report if an image is incomplete or corrupt.
- % The information displayed includes the scene number, the file name, the
- % width and height of the image, whether the image is colormapped or not,
- % the number of colors in the image, the number of bytes in the image, the
- % format of the image (JPEG, PNM, etc.), and finally the number of seconds
- % it took to read and process the image.
- %
- % The format of the ConjureImageCommand method is:
- %
- % MagickBooleanType ConjureImageCommand(ImageInfo *image_info,int argc,
- % char **argv,char **metadata,ExceptionInfo *exception)
- %
- % A description of each parameter follows:
- %
- % o image_info: The image info.
- %
- % o argc: The number of elements in the argument vector.
- %
- % o argv: A text array containing the command line arguments.
- %
- % o metadata: any metadata is returned here.
- %
- % o exception: Return any errors or warnings in this structure.
