.SH NAME
wxGraphicsRenderer \- Functions for wxGraphicsRenderer class
.SH DESCRIPTION
.LP
A \fIwxGraphicsRenderer\fR\& is the instance corresponding to the rendering engine used\&. There may be multiple instances on a system, if there are different rendering engines present, but there is always only one instance per engine\&. This instance is pointed back to by all objects created by it (\fIwxGraphicsContext\fR\&, \fIwxGraphicsPath\fR\& etc\&.) and can be retrieved through their \fIwxGraphicsObject:getRenderer/1\fR\& method\&. Therefore you can create an additional instance of a path etc\&. by calling \fIwxGraphicsObject:getRenderer/1\fR\& and then using the appropriate CreateXXX() function of that renderer\&.

.LP
Returns the default renderer on this platform\&.
.LP
On macOS this is the Core Graphics (a\&.k\&.a\&. Quartz 2D) renderer, on MSW the GDIPlus renderer, and on GTK we currently default to the Cairo renderer\&.

Creates a graphics font with the given characteristics\&.

If possible, the \fIcreateFont/4\fR\& overload taking \fIwxFont\fR\& should be used instead\&. The main advantage of this overload is that it can be used without X server connection under Unix when using Cairo\&.
