<i>fax2ps</i> reads one or more <small>TIFF</small>

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.</td></table>

By default <i>fax2ps</i> generates P <small>OST</small> S

<i>fax2ps</i> generates a compressed form of P
|
|
<small>OST</small> S <small>CRIPT</small> that is optimized
|
|
for sending pages of text to a P <small>OST</small> S
|
|
<small>CRIPT</small> 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 <small>OST</small> S <small>CRIPT</small>
|
|
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 <small>OST</small> S <small>CRIPT</small>
|
|
description, relative to the straightforward imaging of the
|
|
page with a P <small>OST</small> S <small>CRIPT</small>
|
|
<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>tiff2ps</i>(1).</td></table>

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 <small>OST</small> S <small>CRIPT</small>
