<hr><a name="_details"></a><h2>Detailed Description</h2>
101
Interface for drawing.
103
IpePainter-derived classes are used for drawing to the screen and for generating PDF and Postscript output.<p>
104
The <a class="el" href="class_ipe_painter.html">IpePainter</a> maintains a stack of graphics states, which includes stroke and fill color, line width, dash style, miter limit, line cap and line join, and the current transformation matrix. The <a class="el" href="class_ipe_painter.html">IpePainter</a> class takes care of maintaining this stack, and setting of the attributes in the current graphics state.<p>
105
Setting an attribute with a symbolic value is resolved immediately using the <a class="el" href="class_ipe_style_sheet.html">IpeStyleSheet</a> attached to the <a class="el" href="class_ipe_painter.html">IpePainter</a>, so calling the <a class="el" href="class_ipe_painter.html#a16a77ab52b1da7345b02814142719e2">Stroke()</a> or <a class="el" href="class_ipe_painter.html#7723d2c28be7dd411d11c546bd9ff633">Fill()</a> methods of <a class="el" href="class_ipe_painter.html">IpePainter</a> will return the current absolute color.<p>
106
It's okay to set symbolic attributes that the stylesheet does not define - they are set to a default absolute value (normal, black, solid, etc.).<p>
107
A null fill color is drawn as if it was void. Ipe objects exploit this: only group objects ever need to explicitly contain a 'void' fill color.<p>
108
A null stroke color means not to draw any outline on paths. This is only meant to support old Ipe files (before 6.0 pre 25).<p>
109
The correct way to draw filled objects without boundary is to set the line style to 'void'.<p>
110
A null dash style is drawn as solid.<p>
111
A null line width is drawn as whatever is the standard of the drawing medium (that is, as line width 0).<p>
112
The painter is either in "general" or in "path construction" mode. The <a class="el" href="class_ipe_painter.html#c473e683ac238caac0706d06998e8dbf">NewPath()</a> member starts path construction mode. In this mode, only the path construction operators (MoveTo, LineTo, CurveTo, Rect, DrawArc, DrawEllipse, ClosePath), the transformation operators (Transform, Untransform, Translate), and the stack operators (Push, Pop) are admissible. (Pushs and pops must balance inside path construction. Note that pushs and pops inside path construction only affect the current (painter-internal) tranformation matrix, they do not generate Postscript gsave/grestore operators.) The path is drawn using DrawPath, this ends path construction mode. Path construction operators cannot be used in general mode.<p>
113
Derived classes need to implement the DoXXX functions for drawing paths, images, and texts.

Draw the unit circle.
432
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 Bezier curves.<p>
433
The approximation is based on the following: The unit circle arc from (1,0) to (cos a, sin a) be approximated by a Bezier 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>
434
Ipe draws circles by drawing four Bezier curves for the quadrants, and arcs by patching together quarter circle approximations with a piece computed from the formula above.<p>
435
This does not modify the transformation matrix. The path is generated as a sequence MoveTo .. CurveTo .. ClosePath operators, but is not actually drawn (DrawPath is not called).

Draw an arc of the unit circle of length <em>alpha</em>.

<em>alpha</em> is normalized to [0, 2 pi], and applied starting from the point (1,0).<p>
458
The function works by generating a sequence of Bezier splines (see DrawEllipse for details of the transformation). It only generates calls to CurveTo. It is assumed that the caller has already executed a MoveTo to the beginning of the arc at (1,0).<p>
459
This function may modify the transformation matrix.
