In fact, it's a redesign... I think you shouldn't change the DirectFB without experience. I see several problems: 1 DirectFB do blitting line by line. Serious work is needed to change it method. 2 Changing the axes is changing size of surface.
Try to rotate the surface within your app first. 2007/10/23, Bin Chen <[EMAIL PROTECTED]>: > I am sure I need do 90 degree rotation to the screen, i need to modify > the blit function to translate the axis. > > Do you have any better method? > > Bin > > On 10/23/07, Nikita Egorov <[EMAIL PROTECTED]> wrote: > > Do you really sure you need optimization the DirectFB ?
