2.CADisplayLink
1> contains quartzcore frames
2> Fixed refresh frequency (1 seconds Refresh 60 times)
3> requires high refresh speed, suitable for fast refresh
4> Creating DisplayLink
Returns an Cadisplaylink timer object that will call 60 times the target's Sel method in 1 seconds and pass Cadisplaylink as a parameter
execution time can appear the effect is better animation2. Uncertain time gifThe above method is to execute GIF time according to the given constant time 1.5s, the disadvantage is that if the current method as a generic class method, this 1.5s is very unscientific. So the bottom-up method is to first calculate the total length of time for the picture. Perform the animation again.#import TotalTime; Cadisplaylink *displaylink;} @end @implementation mot
the transparency of the Calayer, adding an animation to the view, which will eventually be Calayer tagged and passed Catransaction submits to an intermediate state to go. When all of the above operations are completed, Runloop is about to enter hibernation (or exit), the Observer that is concerned about the event will be notified. At this point the Core Animation registered Observer will be in the callback, all the intermediate state is submitted to the GPU to display, if there is animation, th

2011 up to now, no more Windows drivers.Recently, as a result of the project needs, try to change a graphics card driver (kmdod), in practice, I proved in theory to a driving architecture is correct or not. (USB Display = Kmdod + avstream).Among them, Kmdod is the completion of the display part of the function, complete the VIDPN (Video present network), the driver of the original post physical device into a USB physical device.And avstream The reason for this, the completion is due to the USB V
