In iOS video processing, video decomposition images and image compositing videos are frequently encountered in iOS video processing, and this blog post analyzes the conversion of iOS video images to two parts.(1) Video decomposition imageHere the video decomposition images using Avassetimagegenerator, using this class can be easily implemented under different time stamps, video frame capture. Note that this method of video decomposition of picture fra

Compositing mode: The composition mode represents the relationship of the part and the whole with the tree structure. The compositing mode allows the client to equate a single constituent object with a composite object made up of them.Two forms: according to the implementation of the interface is divided into safe and transparent typeThe composition mode can not provide a management method for the parent ob

In the layer palette, in the mode Drop-down list, there are several modes for compositing. Understanding the role of these models plays an important role in the synthesis of images. The following is a detailed description: Normal mode : This is the basic pattern of drawing and compositing , as well as the standard mode of a layer. When a tonal and selected image area is synthesized into the background, The

In iOS video processing, video exploded images and image compositing videos are frequently encountered problems in iOS video processing. This blog on the two parts of the iOS video image of the mutual conversion to do a bit of analysis.(1) Video decomposition imageHere the video exploded images using a Avassetimagegenerator. using this class can be very convenient to achieve a different time between the Poke, video frame capture.

compiler to synthesize the default constructor. The compiler will only synthesize the default constructor when it is required by the compiler. What kind of class is the compiler need to synthesize the default constructor?　　Summarize: The composite default constructor always does not initialize the class's built-in type and the data members of the composite type. Clearly the default constructor is required by the program and is required by the compiler, and only the default construc

This is a recent technical sharing in the company. It introduced the accelerated compositing mechanism in WebKit. Accelerated compositing (layer-based hybrid acceleration) is mainly used for accelerating CSS 3 animation, apple first introduced WebKit and implemented it on safari. Currently, other major WebKit ports, including QT, chrome, and Android, also provide their respective implementations. Handouts
