Yeah, the C code looks like a fairly typical 2d API. I was just
referring to what I saw in the screenshot, with message boxes<br>
I assume you were using to draw a mustache on Mona Lisa in the
running instace of Pd. But I probably misunderstood what<br>
you were doing.<br>

<pre style=""><pre style=""><font color="#000000"><span style="white-space:pre-wrap">The wrapper offers a layer structure called *t_elayer *that owns a set of
points.
First we create a layer for a t_ebox (GUI object) :
ebox_start_layer(t_ebox *x, t_symbol* name, float width, float height)
To create a path, you can use several functions :
egraphics_move_to(t_elayer *g, float x, float y),
egraphics_line_to(t_elayer *g, floatx, float y),
egraphics_curve_to(t_elayer*g, float ctrl1x, float ctrl1y, float ctrl2x, float ctrl2y, float endx, float endy),
ect...
The functions append points to the t_elayer.
Before drawing all the paths, we apply the matrix transformations and mark
the layer ready to be drawn :</span></font></pre></pre>

Just curious-- in the features you mention translate and rotate, but
not scale and skew. Is there a reason for that?<br>
