.SH NAME
|
|||
|
|
mime.convs \- mime type conversion file for cups (deprecated)
|
|||
|
|
.SH DESCRIPTION
|
|||
|
|
The \fBmime.convs\fR file defines the filters that are available for converting files from one format to another.
|
|||
|
|
The standard filters support text, PDF, PostScript, and many types of image files.
|
|||
|
|
.LP
|
|||
|
|
Additional filters are specified in files with the extension \fI.convs\fR in the CUPS configuration directory.
|
|||
|
|
.LP
|
|||
|
|
Each line in the \fBmime.convs\fR file is a comment, blank, or filter
|
|||
|
|
line.
|
|||
|
|
Comment lines start with the # character.
|
|||
|
|
Filter lines specify the source and destination MIME types along with a relative cost associated with the filter and the filter to run:
|
|||
|
|
.nf
|
|||
|
|
|
|||
|
|
source/type destination/type cost filter
|
|||
|
|
|
|||
|
|
.fi
|
|||
|
|
The \fIsource/type\fR field specifies the source MIME media type that is consumed by the filter.
|
|||
|
|
.LP
|
|||
|
|
The \fIdestination/type\fR field specifies the destination MIME media type that is produced by the filter.
|
|||
|
|
.LP
|
|||
|
|
The \fIcost\fR field specifies the relative cost for running the filter.
|
|||
|
|
A value of 100 means that the filter uses a large amount of resources while a value of 0 means that the filter uses very few resources.
|
|||
|
|
.LP
|
|||
|
|
The \fIfilter\fR field specifies the filter program filename.
|
|||
|
|
Filenames are relative to the CUPS filter directory.
|
|||
|
|
