Yoga, Miix tablets have a gravitational induction function, how to lock the screen rotation, Yoga itself has a gravitational induction physical switch, but Miix no gravity sensor switch, how to shut down the system? Now let's introduce how to turn off the screen rotation in the Windows 88.1 system (Gravity sensor )。 Right-click in the desktop space to open the screen resolution, as shown: Open scre

versus pixels:When using native drawing technologies such as quartz, uikit, and core animation, you specify coordinate values using a logical coordinate space, which measures distances in points. this logical coordinate system is decoupled from the device coordinate space used by the system frameworks to manage the pixels on the screen. generally, the size used in the program is calculated by point. in the old iPhone, point and pixel are hardly distinguished, because they are both and

following graphics initialization functions: void far initgraph (int far *gdriver,int far *gmode,char); where Gdriver and Gmode represent graphics drives and patterns, path refers to the directory path where the graphics driver resides. The symbolic constants and corresponding resolutions for graphics drives, graphics patterns are shown in table 2. The graphics driver is provided by the Turbo C Publisher with the file name extension. BGI. Different graphics drivers are available depending on

Conversion principle and code example of RGB to YUV Conversion principle and code example of RGB to YUV Because H.264 and other compression algorithms are performed in the color space of YUV, color space conversion is required before compression. If the resources collected by the camera are RGB, first convert them to YUV. if the resources are YUV, sort the data according to the YUV format supported by the compressors. This article uses rgb24 à yuv420 (yv12) as an example to explain the

Dip: Device Independent pixels (device independent pixel ). Different devices have different display effects, which are related to the hardware of the device. We recommend that you use this function to support WVGA, hvga, and qvga without pixels.Density-independent pixels, an abstract unit based on the physical density of the screen. Density can be understood as the number of pixels per inch (unit: DPI). 1dp is actually equivalent to a point on the screen with a density of DPI (can it be underst
