recvq/fax* - received facsimile document format
Facsimile received by HylaFAX are placed in the recvq subdirectory.
Each facsimile document is stored as a single Class F Tagged Image File
Format (TIFF) file. This format includes the following information:
o page width and length
o horizontal and vertical resolution
o page orientation
o phone number of the sender
o date and time document was received
o number of scanlines received with errors
o maximum number of consecutive scanlines received with errors
o whether or not bad scanlines were regenerated by the receiver
o make and model of the modem used to receive the document
o name of the host computer on which the document was received
Image data is written using either CCITT T.4 or CCITT T.6 compression.
By default data is written using the compression scheme/data format
negotiated by the sender and receiver. However, if faxgetty(8) is
configured to do copy quality checking then data is written using the
compression scheme defined by the RecvDataFormat configuration
parameter; see hylafax-config(5).
A scanline that is regenerated by the receiver because of an error is
typically just a copy of the previous good scanline.
The files in the recvq directory are created with the protection mode
specified in the server configuration file(s). By default, files are
created with mode 0600 and owned by the fax user, which means that they
are accessible only to the fax user.
To print a facsimile on a POSTSCRIPT(R) printer, the fax2ps(1) program
can be used.
