Chimera Convert Configuration

Chimera can be configured to use other programs to convert data from a form that chimera cannot handle to a form that it can handle. For example, chimera can use a convert program to turn JPEG inline images to GIF inline images. The file that describes the convert configuration is called the convert file. Each convert specification is described by a line in the protocol file. Blank lines or lines beginning with '#' are ignored.

Each protocol entry is made up of the following white space (excluding carriage returns and line feeds) delimited fields: 

use in-content-type out-content-type command

Use

The use field indicates the circumstances for which the conversion will be used. Following is a list of possible use values:

In-Content-Type

This describes the type to be converted. This must match in order for the conversion to be done.

Out-Content-Type

This describes the result of the conversion.

Command

This is the command used to do the conversion. It must accept a filename argument on the command line. The name is the file that contains the data to be converted.
