Hello,

Our app displays images with NativePixelformat set to true. We implemented window/level functionality via setting whitevalue/blackvalue properties of IEbitmap. Works OK, except if a zoomfilter is active. Then setting blackvalue/whitevalue has no effect.

Will this be changed in the foreseeable future, or is this something we have to live with?

Regards, Ronald

Hello,
this is a known problem. Please wait next release for a fix.
You can also fix it opening hyieutils.pas, inside method "TIEBitmap.RenderToTIEBitmap", locate:

ietmp2.RenderToTIEBitmap(.....

Just before above line insert following code:

ietmp2.BlackValue := fBlackValue;
ietmp2.WhiteValue := fWhiteValue;
