<H2>What Is Grid Removal?</H2>
<P>Grid lines in an original image interfere with the automatic line
and point detection algorithms in Engauge Digitizer. In most
cases, however, the grid lines can be quickly removed using
one of the grid removal features offered by Engauge
Digitizer. The resulting processed image can be automatically digitized
using <A HREF="tutorautolinegraph.html#segmentfill">Segment Fill</A> and
<A HREF="tutorautopointgraph.html#pointmatch">Point Match</A>.</P>
<P>Here is an example of how grid removal can clean up an image:</P>

<H2>How Do I Control Grid Removal?</H2>
<P>By simply changing the Grid Removal settings, grid lines can usually be
removed.</P>
<P>Use the Settings/Grid Removal dialog to experiment with various
discretizing settings. You can get more information about the
<A HREF="dlggridremoval.html">Grid Removal dialog</A>.</P>
