prevent memory leakage and enhance program robustness. In terms of code, an ImageManager is used to manage and cache images. The function interface is public void loadBitmap (String url, Handler handler). The url is the image address to be downloaded, handler is the callback after the image is successfully downloaded. It processes the message in handler, and the message contains the image information and bitmap object. The ImageMemoryCache, ImageFile

Map class, we have already written a preliminary article, and the functions still need to be expanded and improved. Now we are trying to move our buffer area. Upload a: 640x480 bitmap: we use this image as a map. We use this material as our map and try to move some of our maps. If we move the whole map, the efficiency will naturally be low. We just move the rectangle in this way, dynamic bitmap cutting method. Keyboard Control Method: (this method is provided by a person on the internet, borrow

However, the image processing efficiency of the GD library is slightly inferior to that of the imagemagick library, therefore, we recommend replacing it with the imagemagick library for image processing. Before you start, make sure that GD or Imagick has been installed locally. When Intervention Image is used, you only need to pass an ar

However, it is necessary to provide an interface that allows users to have the opportunity to do some other special processing of the downloaded

queue to protect your data. When you write code to make a special data structure available only to code that runs in the dispatch queue. Then, as the dispatch queue runs continuously, you will ensure that only one block of code accesses the data structure at the same time.In this application we need to protect two data structures:1. Linkurls array in Imagelistviewcontroller. To protect it, we write code to make it run only in the main thread.2. The pendingzips variable in
