+<h3 class="subsub"><img src="pixmaps/shapes.png"> The shape recognizer</h3>
+<p>
+ The shape recognizer is also a special
+ operating mode of the pen and highlighter tools. When it is enabled,
+ Xournal attempts to recognize geometric shapes as they are drawn, and
+ if successful will replace the drawn strokes accordingly. The shapes
+ that can be recognized are: line segments, circles, rectangles, arrows,
+ triangles and quadrilaterals. Polygonal shapes can be drawn in a single
+ stroke or in a sequence of consecutive strokes.
+</p>
+<p>
+ The recognizer is set to be as unobtrusive as possible, and should not
+ interfere too much with handwriting. (It differs in this and other ways
+ from another shape recognizer written for Xournal by Lukasz Kaiser).
+ As a result, it may only recognize shapes if you draw them carefully and
+ deliberately. Specific tips for better recognition: (1) for circles,
+ a closed curve that isn't quite round works better
+ than a rounder curve that doesn't close; (2) for arrows, it is better
+ to lift the pen before drawing the tip of the arrow, and make sure
+ the tip consists of two straight line segments;
+ (3) for very elongated rectangles,
+ recognition tends to be better if you lift the pen between consecutive
+ sides.

Version 0.4.1 (Sep 15, 2007):
<ul>
<li> bugfix: compatibility with new versions of pdftoppm (thanks to
or whiteout eraser); a value of "highlighter" indicates that the stroke
should be painted in a partially transparent manner (Xournal uses an alpha
coefficient of 0.5).

The <i>color</i> attribute can take one of the standard values "black",
"blue", "red", "green", "gray", "lightblue", "lightgreen", "magenta",
"orange", "yellow", "white", or can specify a hexadecimal RGBA value in
-the format "#rrggbbaa". The <i>width</i> attribute is a floating-point
-number and specifies the width of the stroke in points (1/72 in).

+The <i>width</i> attribute is a floating-point
+number (or a sequence of floating-point numbers starting with version 0.4.2),

+variable-width stroke, the <i>width</i> attribute contains a
+whitespace-separated succession of floating-point values: first the
+nominal brush width, and then the width of each successive segment forming
+the stroke.)

<p>
I have also had a report that one of the workarounds used by Xournal to
bypass a calibration bug in GTK+ can actually entirely prevent strokes
from being drawn. If you are being unsuccessful at drawing in Xournal
-with XInput enabled, try recompiling after changing the first line of
-<tt>src/main.c</tt> to

If this modification does improve things for you, and if you have a bit
of spare time to help investigate the causes of this problem, please
contact me.
