15.1 gzipGzip (1) is the GNU compression program. It compresses only a single file. The basic usage is as follows:$ gzip filenameAfter the program executes, the file name becomes filename.gz, and in general the size is smaller than the original file. Note that the program does not create a new file filename.gz, but instead changes the filename to filename.gz. Generally speaking, the compression rate of text files is higher. And those JPEG images, MP3 and other similar files compression rate is n

When you insert a picture in a Word2010 document, if the picture is large in size, the file size of the Word document becomes large. Even if you change the size of a picture in a Word document or crop a picture, the size of the picture does not change. However, users can compress all the pictures or selected pictures in the Word2010 document, which can reduce the size of the picture effectively, and reduce the size of the Word2010 file. To

Android bitmap compressWith the development of mobile phone hardware, android camera functions become more and more powerful, and can find high-resolution images.In some scenarios, you need to take photos and upload them to the service. However, because the image size is too large, uploading will be very slow (in some network scenarios) and will consume a lot of traffic, to achieve high speed, we need to reduce the image size. There are two ways to reduce the image size: 1. Take a small image; 2

GZipStream class Provides methods and attributes for compressing and extracting streams. This class represents the GZip data format, which uses industry-standard algorithms for lossless compression and decompression of files. This format includes a cyclic redundancy check value that detects data corruption. GZip uses the same algorithm as DeflateStream, but it can be extended to use other compression formats. This format can be easily implemented in a way that does not involve the right to use a

Although you can reduce the size of a word file by compressing all the pictures or the size of the pictures in the Word2007 document, it is cumbersome to perform a compression operation each time. The user can set picture compression options to achieve the purpose of automatically compressing picture dimensions when saving Word documents, as described in the following steps: Step 1th, open the Word2007 document window and select any picture. On the Format tab of the Open Picture Tools ribbon, c

Recently wanted to use Layabox to make a small game, however Laya itself does not own the build tool. Then think of writing modular things or use Webpack to make, with ES6 grammar is also relatively clear.So it was loaded with Webpack, only babel-loader to compile code written in ES6. The configuration file is as follows:Const WEBPACK = require (' webpack '= { entry: { index:'./src/scence1.js ' }, Output: { ' [name].js ', + '/src ' }, module: { rules: [{ /\.js$ /, /nod
