CFbsFont Class Reference

class CFbsFont : public CFont

Font managed by the font and bitmap server. CFbsFont objects are used for screen and off-screen bitmap fonts. They are usually obtained by calls to the CBitmapDevice::GetNearestFontInPixels() and MGraphicsDeviceMap::GetNearestFontInTwips() functions. The class implements a number of functions inherited from CFont. CBitmapDevice::GetNearestFontInPixels()

MGraphicsDeviceMap::GetNearestFontInTwips()
