◆ setSimplificationTolerance()
void QgsGeometryPaintEngine::setSimplificationTolerance |
( |
double |
tolerance | ) |
|
Sets a simplification tolerance (in painter units) to use for on-the-fly simplification of geometries while rendering.
This will result in simpler, generalised paths.
Set tolerance to 0 to disable simplification. (No simplification is the default behavior).

( |
int |

Sets the number of segments to use when drawing stroked paths with a rounded pen.
The default is 8 segments, a smaller number will result in simpler paths.
