Hi,
The problem is I dont want to ship databases with bitmap families,
but rather display bitmap as is so that 1pix in bitmap is rendered to
exactly 1phisical devise pixel.
What I experience and try to avoid is scaling the bitmap on high-density
displays!
I tried WinSetScalingMode(kBitmapScalingOff);
I tried WinSetCoordinateSystem(kDensityDouble/ kDensityLow);
I tried BmpCreateBitmapV3(pBmpV1, kDensityDouble/ kDensityLow,
BmpGetBits(pBmpV1)...);
I tried WinCreateOffscreenWindow(...nativeFormat/ screenFormat);
Nothing worked as targetted.
What I need is effect of drawing bitmap (BitmapTypeV3) with kDensityDouble.
Thanks!
