Reprint Please specify source: http://blog.csdn.net/zhaokaiqiang1992Bitmap's handling has always been a big problem in Android development, because with a little attention, bitmap will be able to eat all of our memory and then crash and exit! However, as long as we have mastered some of bitmap's common processing skills, we can effectively avoid this problem, henceforth no longer afraid of bitmap.The pictures have different shapes and sizes. In most c

High-performance datagram Matching Structure Based on index and bitmap, and high-performance bitmapAfter I wrote two proposition compositions, I couldn't get rid of it... I'm on a business trip in Beijing. I'll have two more essays before I leave! (Written on the evening of February 21, and entered Beijing the next day)When I describe the data packet classification Dimension Tree structure, a large number of binary Tree structures are used. This means

It's not hard to understand the word mass data. Mainly for a given amount of data is particularly large, occupy a particularly large memory situation. So what's the relationship to the bitmap? Look at the following example of Tencent's massive data. For example: 4 billion unsigned integers that are not repeated are not ordered. Give an unsigned integer how to quickly determine whether a number is in these 4 billion numbers. For this problem, we gave

Detailed description of the canvas-based video mask plug-in, detailed description of the canvas mask Adds a cover for a video to block a video area. During a certain video period, for example, the area between 10th and 20th minutes is not displayed. Application scenarios include hiding TV icons, blocking advertisements in the lower right corner of the video, and acting as mosaic. A long video may contain mu

The Winform application implements a general mask layer and a winform mask. On the WEB, when we need to process big data or complex logic, because of the long time consumption, we usually display a translucent mask layer on the page during processing, put an icon or prompt above: processing... in this way, the user experience is better. However, in Winform client

In OpenCV, the more common is the rectangular mask cvrect, does not specifically provide a circular mask, then we can only write a function to simulate the circle mask, need to provide the size of the original image, as well as the center of the circle mask position and radius, return a CV:: Mat type

The previous article describes how to use bitmap to sort non-duplicate data. The Sorting Algorithm is ready at a moment. I want to test the big data, because small data is quickly ranked in the memory. I. dataset generation requirements 1. The data is an integer in the range of 0--2147483647 (2 ^ 31-1; 2. The dataset contains an integer ranging from 0 to 2 ^ 31-1 of 60%, that is, the number of kicked 40%; 3. No duplicate data in the dataset, that is,

At Oracle 9i or above, Oracle sometimes chooses to convert the B-Tree index to BITMAP for SQL Execution, resulting in an extremely bad execution plan. The conversion is determined by the hidden parameter _ B _tree_bitmap_plans. If this parameter is set to true, it is converted. Otherwise, no conversion is performed. In 8i, the default value of this parameter is false, Therefore, only when a bitmap index exi
