It produces an ESC/P2 +raster graphic printer control stream as output. + +<P> This program creates an output that is printable on Epson printers +that understand the <a +href="http://www.epson.co.uk/support/manuals/pdf/ESCP/Part_1.pdf">ESC/P2 +printer control language</a> (e.g. the Stylus models). For older +Epson 9-pin dot matrix printers, which use the ESC/P protocol, see +<B>pbmtoepson</B>. + +<A NAME="lbAE"> </A> +<H2>OPTIONS</H2> + +<dl COMPACT> + +<dt><b>-compress=</b><i>compressionmode</i> + +<dd>This determines the compression mode that <b>pbmtoescp2</b> uses +in its output. Valid values for <I>compressionmode</I> are <b>0</b> +and <b>1</b>. <b>-compress=0</B> results in a printer control stream +with uncompressed raster graphic data. <b>-compress=1</b> results in +a printer control stream with RLE compressed raster graphic data +(RLE means Run Length Encoding). The default is <b>-compress=1</b>. +</dd> + +<dt><b>-resolution=</b><i>dpi</i></dt> + +<dd>This determines the horizontal and the vertical print resolution +set in the printer control stream. Another way of looking at it is a +declaration of what the resolution of the input image is (PBM images +don't have inherent resolution). Valid values for <i>dpi</i> are +<b>180</b> and <b>360</b>. See <a href="#hints">hints</a> for more +information on this. + +<p>The default is <b>-resolution=360</b>. + + +</dd> + +</dl> + +<H2 id="hints">HINTS</H2> + +<P>RLE compresses very well bitmaps of line drawings, preferably +horizontal oriented contents like texts, sheets of music, etc. +However, bitmaps derived from photographs are not ideal for RLE. In +extreme cases, when no byte repetitions occur in the input, the result +will be even slightly bigger than the input. To avoid this, use +compression mode 0 to switch off RLE. + +<p>Each pixel in the input PBM image becomes one dot in the printed +output. Therefore, you must make sure the width and height of the +input are appropriate for the print resolution you choose and the +print area you want. E.g. if you print at 180 dpi and want the image +to print as 8 inches by 10, you must supply a PBM that is 1440 +pixels wide by 1800 pixels high. You can adjust the size of the +input with <b>pamscale</b>, <b>pamstretch</b>, <b>pbmreduce</b>, or +<b>pamenlarge</b>. + + +<A NAME="lbAG"> </A> +<H2>SEE ALSO</H2> + +<B><A HREF="escp2topbm.html">escp2topbm</A></B>, +<B><A HREF="pbmtoepson.html">pbmtoepson</A></B>, +<B><A HREF="pamscale.html">pamscale</A></B>, +<B><A HREF="pamstretch.html">pamstretch</A></B>, +<B><A HREF="pbmreduce.html">pbmreduce</A></B>, +<B><A HREF="pamenlarge.html">pamenlarge</A></B>, +<B><A HREF="pbm.html">pbm</A></B> + +<A NAME="lbAH"> </A> +<H2>AUTHOR</H2> + +<P>Copyright (C) 2003 by Ulrich Walcher (<A +HREF="mailto:u.walcher@gmx.de">u.walcher@gmx.de</A>). + +<A NAME="history"> </A> +<H2>HISTORY</H2> + +<p><b>pbmtoescp2</b> was added to Netpbm in Release 10.18 (August 2003); +it was created around the same time. + +<HR> +<A NAME="index"> </A> +<H2>Table Of Contents</H2> +<UL> +<LI><A HREF="#lbAB">NAME</A> +<LI><A HREF="#lbAC">SYNOPSIS</A> +<LI><A HREF="#lbAD">DESCRIPTION</A> +<LI><A HREF="#lbAE">OPTIONS</A> +<LI><A HREF="#hints">HINTS</A> +<LI><A HREF="#lbAG">SEE ALSO</A> +<LI><A HREF="#lbAH">AUTHOR</A> +<LI><A HREF="#history">HISTORY</A> +</UL> +</BODY> +</HTML> + |
