75
Interface for drawing. 
 
76
<p>
 
77
IpePainter-derived classes are used for drawing to the screen and for generating PDF output.<p>
 
78
The IpePainter 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 IpePainter class takes care of maintaining this stack, and setting of the attributes in the current graphics state.<p>
 
79
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 IpePainter, so calling the <a class="el" href="class_ipe_painter.html#a31">Stroke()</a> or <a class="el" href="class_ipe_painter.html#a32">Fill()</a> methods of IpePainter will return the current absolute color.<p>
 
80
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>
 
81
Attributes must not be changed after a path has been started. (Although this does not seem to be stated explicitely in the PDF Reference, Acrobat Reader 4 complains if the dash style is set after a path has been defined.)<p>
 
82
Derived classes need to implement the functions for drawing paths, images, and texts.<p>
 
83
A null color is drawn as if it was void. Ipe objects exploit this: only group objects ever need to explicitly contain a 'void' color.<p>
 
84
A null dash style is drawn as solid.<p>
 
85
A null line width is drawn as whatever is the standard of the drawing medium.

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>
 
684
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>
 
685
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>
 
686
This does not modify the transformation matrix. The path is generated as a sequence BeginClosedPath .. CurveTo .. EndClosedPath, but is not actually drawn (DrawPath is not called).     </td>
