<p style="margin-left:11%; margin-top: 1em"><i>fax2ps</i>

reads one or more <small>TIFF</small> facsimile image files
|
|
|
|
|
and prints a compressed form of <br>

|

|
|
|
|
|
|
|
|
|
|
<p style="margin-left:11%; margin-top: 1em">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>

|
|
<p style="margin-left:11%; margin-top: 1em">By default

<i>fax2ps</i> generates for all pages in the file. The
|
|
|
|
|
<b>−p</b> option can be used to select one or more

|
|
<p style="margin-left:11%; margin-top: 1em"><i>fax2ps</i>
|
|
|
|
|
generates a compressed form of that is optimized for sending
|
|
|
|
|
pages of text to a 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 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 description, relative to the straightforward imaging
|
|
|
|
|
of the page with a <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).</p>
