This article is about
image points to the position of the image before rotation is basically not likely to be positive, so it is necessary to use bilinear interpolation (the theory of the specific analysis in the previous article in detail mentioned).The main code is as follows:/******************* image rotation ******************/int centerofrotation_x = mydraw_width/2;//Rotation C
After IOS upgrades to 10, you will find that you are unable to perform a true machine test. I also encountered this in the iOS 8.4, 9.3 update.
