| 53 | <p><i>fax2ps</i> reads one or more <small>TIFF</small>
|
|---|
| 54 | facsimile image files and prints a compressed form of
|
|---|
| 55 | PostScript on the standard output that is suitable for
|
|---|
| 56 | printing.</p>
|

| 57 | <!-- INDENTATION -->
|
|---|
| 58 | <p>By default, each page is scaled to reflect the image
|
|---|
| 59 | dimensions and resolutions stored in the file. The
|
|---|
| 60 | <b>−x</b> and <b>−y</b> options can be used to
|
|---|
| 61 | specify the horizontal and vertical image resolutions
|
|---|
| 62 | (lines/inch), respectively. If the <b>−S</b> option is
|
|---|
| 63 | specified, each page is scaled to fill an output page. The
|
|---|
| 64 | default output page is 8.5 by 11 inches. Alternate page
|
|---|
| 65 | dimensions can be specified in inches with the
|
|---|
| 66 | <b>−W</b> and <b>−H</b> options.</p>
|
|---|
| 67 | <!-- INDENTATION -->
|
|---|
| 68 | <p>By default <i>fax2ps</i> generates PostScript for all
|
|---|
| 69 | pages in the file. The <b>−p</b> option can be used to
|
|---|
| 70 | select one or more pages from a multi-page document.</p>
|
|---|
| 71 | <!-- INDENTATION -->
|
|---|
| 72 | <p><i>fax2ps</i> generates a compressed form of PostScript
|
|---|
| 73 | that is optimized for sending pages of text to a PostScript
|
|---|
| 74 | printer attached to a host through a low-speed link (such as
|
|---|
| 75 | a serial line). Each output page is filled with white and
|
|---|
| 76 | then only the black areas are drawn. The PostScript
|
|---|
| 77 | specification of the black drawing operations is optimized
|
|---|
| 78 | by using a special font that encodes the move-draw
|
|---|
| 79 | operations required to fill the black regions on the page.
|
|---|
| 80 | This compression scheme typically results in a substantially
|
|---|
| 81 | reduced PostScript description, relative to the
|
|---|
| 82 | straightforward imaging of the page with a PostScript
|
|---|
| 83 | <i>image</i> operator. This algorithm can, however, be
|
|---|
| 84 | ineffective for continuous-tone and white-on-black images.
|
|---|
| 85 | For these images, it sometimes is more efficient to send the
|
|---|
| 86 | raster bitmap image directly; see <b>tiff2ps</b>(1).</p>
