The
HalfZooming
renderer lets you control the way your graphic objects will grow or
shrink when you zoom in or out. You can specify the following
parameters:
- Maximum zoom level above which the objects will stop growing; their size will stay fixed past this zoom level.
- Minimum zoom level below which the objects will not be drawn any more; they will be replaced by gray boxes, or will keep a fixed size.
You can also specify an initial zoom factor
by which the minimum and maximum zoom levels will be multiplied.
The following table lists the properties of the
HalfZooming
