Thanks Rick! I wonder what happens to the pressure information if the user has a habit of resting their palm on the screen as they write. I'm sure it is only sensitive to the pen tip but the pressure varies as the writer pivots on the palm. Hmm. Not important... I suppose to get more details one would have to dig around the MS announcements or any papers they've published in the recent past. len -----Original Message----- From: Rick Jelliffe [mailto:ricko@a...] From: "Bullard, Claude L (Len)" <clbullar@i...> > What exactly is INK? It seems to be a vector format storing (sampled) gestures from a pen. The sampling rate seems to be hardware-dependent. Each sampled point seems to contain pressure information. Different pen tips can be stored for faithful rendering/resizing at differing resolutions. The vectors can have text recognition applied: CJK writing has a very fixed order, so storing the stroke order and direction (rather than just a bit map) is important and may allow better recognition than bad Latin writing could have. But the usual thing would seem to be storing the graphic and overlaying it on some other image: if the text recognition fails, you still have the vector format.
