<hr/><a name="_details"></a><h2>Detailed Description</h2>
127
<p>Interface for drawing. </p>
128
<p>Painter-derived classes are used for drawing to the screen and for generating PDF and Postscript output.</p>
129
<p>The <a class="el" href="classipe_1_1_painter.html" title="Interface for drawing.">Painter</a> maintains a stack of graphics states, which includes stroke and fill color, line width, dash style, miter limit, line cap and line join. It also maintains a separate stack of transformation matrices. The <a class="el" href="classipe_1_1_painter.html" title="Interface for drawing.">Painter</a> class takes care of maintaining the stacks, and setting of the attributes in the current graphics state.</p>
130
<p>Setting an attribute with a symbolic value is resolved immediately using the stylesheet <a class="el" href="classipe_1_1_cascade.html" title="A cascade of style sheets.">Cascade</a> attached to the <a class="el" href="classipe_1_1_painter.html" title="Interface for drawing.">Painter</a>, so calling the <a class="el" href="classipe_1_1_painter.html#a4aa37b34a58998f659afea439b46d1ae" title="Return current stroke color.">stroke()</a> or <a class="el" href="classipe_1_1_painter.html#af322ad5dc2602815fee306d978ef298d" title="Return current fill color.">fill()</a> methods of <a class="el" href="classipe_1_1_painter.html" title="Interface for drawing.">Painter</a> will return the current absolute color.</p>
131
<p>It's okay to set symbolic attributes that the stylesheet does not define - they are set to a default absolute value (black, solid, etc.).</p>
132
<p>The painter is either in "general" or in "path construction" mode. The <a class="el" href="classipe_1_1_painter.html#a580edf6422147229766c369a120f1db7" title="Enter path construction mode.">newPath()</a> member starts path construction mode. In this mode, only the path construction operators (moveTo, lineTo, curveTo, rect, drawArc, closePath), the transformation operators (transform, untransform, translate), and the matrix stack operators (pushMatrix, popMatrix) are admissible. The path is drawn using drawPath, this ends path construction mode. <a class="el" href="classipe_1_1_path.html" title="The path object (polylines, polygons, and generalizations).">Path</a> construction operators cannot be used in general mode.</p>
133
<p>The graphics state for a path must be set before starting path construction mode, that is, before calling <a class="el" href="classipe_1_1_painter.html#a580edf6422147229766c369a120f1db7" title="Enter path construction mode.">newPath()</a>.</p>
134
<p>Derived classes need to implement the doXXX functions for drawing paths, images, and texts. The transformation matrix has already been applied to the coordinates passed to the doXXX functions. </p>

<p>Draw an arc of the unit circle of length <em>alpha</em>. </p>
1509
<p>PDF does not have an "arc" or "circle" primitive, so to draw an arc, circle, or ellipse, Ipe has to translate it into a sequence of <a class="el" href="classipe_1_1_bezier.html" title="A cubic Bezier spline.">Bezier</a> curves.</p>
1510
<p>The approximation is based on the following: The unit circle arc from (1,0) to (cos a, sin a) be approximated by a <a class="el" href="classipe_1_1_bezier.html" title="A cubic Bezier spline.">Bezier</a> spline with control points (1, 0), (1, beta) and their mirror images along the line with slope a/2, where beta = 4.0 * (1.0 - cos(a/2)) / (3 * sin(a/2))</p>
1511
<p>Ipe draws circles by drawing four <a class="el" href="classipe_1_1_bezier.html" title="A cubic Bezier spline.">Bezier</a> curves for the quadrants, and arcs by patching together quarter circle approximations with a piece computed from the formula above.</p>
1512
<p><em>alpha</em> is normalized to [0, 2 pi], and applied starting from the point (1,0).</p>
1513
<p>The function generates a sequence of <a class="el" href="classipe_1_1_bezier.html" title="A cubic Bezier spline.">Bezier</a> splines as calls to curveTo. It is assumed that the caller has already executed a moveTo to the beginning of the arc at (1,0).</p>
1514
<p>This function may modify the transformation matrix. </p>
