I was the last maintainer and have no will or need to keep it. Raster wants to remove it soon. that said, the acceleration DirectFB provides is crap... particularly on most hardwares for current UI needs. What it does is easy layering of hw-capable videos, so you can have 4-5 different planes hw-blended (usually 1 background, 1 on-screen-display/gui, 2 video). Most of them offer solid color fill (rectangle) and image (sometimes ARGB, sometimes RGB... most of times no colorizing or fading). When they do not offer an alternative, DirectFB automatically fallsback to software, being as slow. -- Gustavo Sverzut Barbieri http://profusion.mobi embedded systems -------------------------------------- MSN: barbi...@gmail.com Skype: gsbarbieri Mobile: +55 (19) 9225-2202 ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
