Hello,
I was using TeeChart Pro v2013.08.130521 32bit VCL with XE3 C++ Builder and recently switched to XE6 with TeeChart v2014.11.140512.

I'm using teechart as kind of a graphic osciloscope. Picture generated elsewhere and stored in TBitmap is shown as a background of a chart using TChart->BackImage->Assign(TBitmap). In old version it looked like this:

Pixels could be clearly distinguished even with zoom.
With new version it looks like this:

Picture is anti-aliased and white background become grayish - it was white. No code has changed since the upgrade. Is there any way to make it look like before?
