AW: Investigated, very interesting. The imported bitmap has a PrefMapMode of
MAP_PIXEL and a PrefSize of (113, 23), this is the same in 3.0 and 3.1. The
difference happens when this is changed to logical sizes. In 3.0, this chage is
done (starting from old DoPaintObject) in ImpCalcBmpFillSizes using:
if( MAP_PIXEL == aBmpPrefMapMode.GetMapUnit() )
rBmpOutputSize = Application::GetDefaultDevice()->PixelToLogic(
aBmpPrefSize,
rOutputMapMode );
else
rBmpOutputSize = OutputDevice::LogicToLogic( aBmpPrefSize,
aBmpPrefMapMode,
rOutputMapMode );
while the primitive version adapts the pixel to logic size much earlier using:
aBitmap.SetPrefSize(Application::GetDefaultDevice()->LogicToLogic(
aBitmap.GetPrefSize(),
aBitmap.GetPrefMapMode(), aDestinationMapUnit));
The very intersting thing is the exception in the old version for bitmaps: it
leads to another result:
PixelToLogic(Size(113, 23), MAP_100TH_MM) -> (3986, 811)
LogicToLogic(Size(113, 23), MAP_PIXEL, 100TH_MM) -> (2990, 609)
where both versions use Application::GetDefaultDevice() for the PixelToLogic
call. I would have expected the same results for both calls ?!?
AW->PL: Any hints why both calls give different results ...???
