David and Hussein, I'm running out of gas so this will be my last entry this evening. I will try to complete the remaining topics tomarrow. Glen Rippel Hinting: Yes, hinting is very difficult, and implemented differently depending on the format. Most fonts require a good set of hints below 60 pixels. Hints maintain the uniform stroke thickness, uniform character heights, and baseline references, side bearings, ect..... and allow for hours of stress free reading. Allowing designers to choose any font format combination for authoring and maintaining the original font fidelity is almost an impossible goal and this is achieved by using TrueDoc. TrueDoc has a unique automatic hinting process which is applied to the character shapes during the authoring process. The results of the TrueDoc character recording process are excellent and can only be improved upon by font designers hand tuning for discrete point sizes. In addition to TrueDoc's excellent auto-hinting process, our OEMs and ISVs also can make use of TrueDoc's anti-alias modules that deliver grey scale bitmaps during the rendering process. Bitmaps can be delivered which are 32K pixels high. Rendering speed of bitmaps for screens are in the range of 400 to 500 characters per second on a 486/66. Once generated and cached, the performance is limited mostly by the blit operations.
