arcobjects - How to set min and max value for stretchType: esriRasterStretch_PercentMinimumMaximum

How can I set the min and max values for the stretch type "Percent Clip" in arcobjects?

It's possible to set the Stretch type:

rasterStretch.StretchType = esriRasterStretchTypesEnum.esriRasterStretch_PercentMinimumMaximum;

But I have no idea how I can set the min and max values (like in the Properties Dialog of ArcMap).
