If + <b>--bgcolor</b> is not specified, <b>pampaintspill</b> makes an + educated guess about the background color based on the colors in the + image's corners.</dd> + + <dt><b>--wrap</b></dt> + <dd>Allow gradients to wrap around image borders. That is, colors + that spill off the right side of the image reappear on the left side of + the image and likewise for left/right, top/bottom, and + bottom/top. <b>--wrap</b> makes images tileable, which is nice for + producing desktop backgrounds.</dd> + + <dt><b>--all</b></dt> + <dd>Recolor all pixels, not just background pixels. Normally, + non-background-colored pixels in the input image appear unmodified in + the output image. With <b>--all</b>, <em>all</em> pixels are colored + based on their distance from all of the (other) non-background-colored + pixels.</dd> + + <dt><b>--downsample</b>=<i>number</i></dt> + <dd>Ignore all but <i>number</i> non-background-colored pixels. + When a large number of pixels in the input image differ in color from + the background, <b>pampaintspill</b> runs very slowly. The + <b>--downsample</b> option randomly selects a given number of colored + pixels to use as paint sources for the gradients and ignores the rest, + thereby trading off image quality for speed of execution.</dd> + + <dt><b>--power</b>=<i>number</i></dt> + <dd>Control how color intensity changes as a function of the + distance from a paint source. The default value for <i>number</i> is + -2.0, which means that intensity drops (because of the minus sign) with + the square (because of the 2.0) of the distance from each paint + source. -2.0 generally works well in practice, but other values can be + specified for various special effects. With very small numbers of paint + sources, -1.0 may produce subtler gradients, but these get muddier as + the number of paint sources increases. Positive numbers (e.g., 1.0 and + 2.0) make the paint sources stand out in the output image by pushing the + gradients away from them.</dd> +</dl> + + +<h2 id="see_also">SEE ALSO</h2> + +<ul> +<li><a href="pamgradient.html">pamgradient</a> +<li><A href="ppmmake.html"><b>ppmmake</b></A>, +<li><A href="ppmrainbow.html"><b>ppmrainbow</b></A>, +<li><A href="pgmramp.html"><b>pgmramp</b></A>, +<li><A href="ppmpat.html"><b>ppmpat</b></A>, +<li><a href="pam.html">pam</a> +</ul> + +<h2 id="history">HISTORY</h2> + +<p><b>pampaintspill</b> was new in Netpbm 10.50 (March 2010). + + +<h2 id="copyright">COPYRIGHT</h2> + +<p>Copyright © 2010 Scott Pakin, <a href= +"mailto:scott+pbm@pakin.org"><i>scott+pbm@pakin.org</i></a>.</p> + +<hr /> + +<h2 id="index">Table Of Contents</h2> + +<ul> + <li><a href="#name">NAME</a></li> + <li><a href="#synopsis">SYNOPSIS</a></li> + <li><a href="#description">DESCRIPTION</a></li> + <li><a href="#options">OPTIONS</a></li> + <li><a href="#see_also">SEE ALSO</a></li> + <li><a href="#history">HISTORY</a></li> + <li><a href="#copyright">COPYRIGHT</a></li> +</ul> + +</body> +</html> + diff --git a/pamslice.html b/pamslice.html index efb42efe..e0e40566 100644 --- a/pamslice.html +++ b/pamslice.html @@ -3,16 +3,14 @@ <HEAD><TITLE>Pamslice User Manual</TITLE></HEAD> <BODY> <H1>pamslice</H1> -Updated: 22 June 2002 +Updated: 8 February 2010 <BR> <A HREF="#index">Table Of Contents</A> -<A NAME="lbAB"> </A> <H2>NAME</H2> pamslice - extract one line of values out of a Netpbm image -<A NAME="lbAC"> </A> -<H2>SYNOPSIS</H2> +<H2 id="synopsis">SYNOPSIS</H2> <B>pamslice</B> {<B>-row=</B><i>rownumber</i> | <B>-column=</B><i>columnnumber</i>} @@ -24,8 +22,7 @@ pamslice - extract one line of values out of a Netpbm image You may use two hyphens instead of one.
