Hello! I am new to DirectFB and have low understanding of how really DirectFB works. Please, help me in advice.
I am using QT for develop my GUI application. I have proprietary graphic libs (provides blit, drawRect, etc) for several platforms with unified api. To get the hardware acceleration i wrote gfxplugin for QT that use this graphic libs, but i am do not get suitable performance for my application. I read in another thread: On Fri, May 7, 2010 at 6:18 PM, Melwyn Lobo <[email protected]> wrote: > Hi , > I must say I was really impressed with performances of DirectFB when > compiling Qtopia 4.6.2 and using DirectFB as Gfx driver....

That mean if i will use DirectFB whithout gfxdriver than i can to get 3 times better performnace? I can't understand this... If DirectFB use only QT software fallback... How we get better performace???!!! So, i think if i try to write gfxdriver for DirectFB that will use this graphic libs, can i get more better performace? Thank you!! _______________________________________________ directfb-users mailing list [email protected] http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-users
