|

|
||
|
|
reads one or more
|
||
|
|
<FONT SIZE="-1">TIFF</FONT>
|
||
|
|
facsimile image files and prints a compressed form of
|
||
|
|
P<FONT SIZE="-2">OST</FONT>S<FONT SIZE="-2">CRIPT</FONT> on the standard output that is suitable for printing.
|
||
|
|
<P>
|
||
|
|
|
||
|
|
By default, each page is scaled to reflect the
|
||
|
|
image dimensions and resolutions stored in the file.
|
||
|
|
The
|
||
|
|
<B>-x</B>
|
||
|
|
|
||
|
|
and
|
||
|
|
<B>-y</B>
|
||
|
|
|
||
|
|
options can be used to specify the horizontal and vertical
|
||
|
|
image resolutions (lines/inch), respectively.
|
||
|
|
If the
|
||
|
|
<B>-S</B>
|
||
|
|
|
||
|
|
option is specified, each page is scaled to fill an output page.
|
||
|
|
The default output page is 8.5 by 11 inches.
|
||
|
|
Alternate page dimensions can be specified in inches with the
|
||
|
|
<B>-W</B>
|
||
|
|
|
||
|
|
and
|
||
|
|
<B>-H</B>
|
||
|
|
|
||
|
|
options.
|
||
|
|
<P>
|
||
|
|
|
||
|
|
By default
|
||
|
|
<I>fax2ps</I>
|
||
|
|
|
||
|
|
generates P<FONT SIZE="-2">OST</FONT>S<FONT SIZE="-2">CRIPT</FONT> for all pages in the file.
|
||
|
|
The
|
||
|
|
<B>-p</B>
|
||
|
|
|
||
|
|
option can be used to select one or more pages from
|
||
|
|
a multi-page document.
|
||
|
|
<P>
|
||
|
|
|
||
|
|
<I>fax2ps</I>
|
||
|
|
|
||
|
|
generates a compressed form of P<FONT SIZE="-2">OST</FONT>S<FONT SIZE="-2">CRIPT</FONT> that is
|
||
|
|
optimized for sending pages of text to a P<FONT SIZE="-2">OST</FONT>S<FONT SIZE="-2">CRIPT</FONT>
|
||
|
|
printer attached to a host through a low-speed link (such
|
||
|
|
as a serial line).
|
||
|
|
Each output page is filled with white and then only
|
||
|
|
the black areas are drawn.
|
||
|
|
The P<FONT SIZE="-2">OST</FONT>S<FONT SIZE="-2">CRIPT</FONT> specification of the black drawing operations
|
||
|
|
is optimized by using a special font that encodes the
|
||
|
|
move-draw operations required to fill
|
||
|
|
the black regions on the page.
|
||
|
|
This compression scheme typically results in a substantially
|
||
|
|
reduced P<FONT SIZE="-2">OST</FONT>S<FONT SIZE="-2">CRIPT</FONT> description, relative to the straightforward
|
||
|
|
imaging of the page with a P<FONT SIZE="-2">OST</FONT>S<FONT SIZE="-2">CRIPT</FONT>
|
||
|
|
<I>image</I>
|
||
|
|
|
||
|
|
operator.
|
||
|
|
This algorithm can, however, be ineffective
|
||
|
|
for continuous-tone and white-on-black images.
|
||
|
|
For these images, it sometimes is more efficient to send
|
||
|
|
the raster bitmap image directly; see
|
||
|
|
<I><A HREF="tiff2ps+1.html">tiff2ps</A></I>(1).

Some messages about malformed
|
||
|
|
<FONT SIZE="-1">TIFF</FONT>
|
||
|
|
images come from the
|
||
|
|
<FONT SIZE="-1">TIFF</FONT>
|
||
|
|
library.
|
||
|
|
<P>
|
||
|
|
|
||
|
|
Various messages about badly formatted facsimile images
|
||
|
|
may be generated due to transmission errors in received
|
||
|
|
facsimile.
|
||
|
|
<I>fax2ps</I>
|
||
|
|
|
||
|
|
attempts to recover from such data errors by resynchronizing
|
||
|
|
decoding at the end of the current scanline.
|
||
|
|
This can result in long horizontal black lines in the resultant
|
||
|
|
P<FONT SIZE="-2">OST</FONT>S<FONT SIZE="-2">CRIPT</FONT> image.

|

|
|
|
||
|
|
If the destination printer supports P<FONT SIZE="-2">OST</FONT>S<FONT SIZE="-2">CRIPT</FONT> Level II then
|
||
|
|
it is always faster to just send the encoded bitmap generated
|
||
|
|
by the

<I><A HREF="tiff2ps+1.html">tiff2ps</A></I>(1)

should probably figure out when it is doing a poor

job of compressing the output and just generate

|
|
P<FONT SIZE="-2">OST</FONT>S<FONT SIZE="-2">CRIPT</FONT> to image the bitmap raster instead.
