+<h2>wx.PseudoDC</h2>
+
The wx.PseudoDC class provides a way to record operations on a DC and then
play them back later. The PseudoDC can be passed to a drawing routine as
if it were a real DC. All Drawing methods are supported except Blit but
</pre>
The operations can be tagged with an id in order to associated them with a
specific object. To do this use:<pre>
-SetId(id)
+ SetId(id)
</pre>
Every operation after this will be associated with id until SetId is called
again. The PseudoDC also supports object level clipping. To enable this use:<pre>
-SetIdBounds(id,rect)
+ SetIdBounds(id,rect)
</pre>
for each object that should be clipped. Then use:<pre>
-DrawToDCClipped(dc, clippingRect)
+ DrawToDCClipped(dc, clippingRect)
</pre>
To draw the PseudoDC to a real dc. This is useful for large scrolled windows
where many objects are offscreen.
Objects can be moved around without re-drawing using:<pre>
-TranslateId(id, dx, dy)
+ TranslateId(id, dx, dy)
</pre>
To re-draw an object use:<pre>
-ClearId(id)
-SetId(id)
+ ClearId(id)
+ SetId(id)
</pre>
and then re-draw the object.
