compression

问题 I am using ZIpstorer class library to compress files. I am able to zip a file by calling zip.AddFile procedure. But I want to zip folders which has subfolders too. So the resulting zip file should have folder and subfolder structure inside the zip file normally. I am not able to do it. if i process each file by looping all folders and sub folders and then if call zip.Addfile then it will result in zip file with all the files inside it without a directory structure. So how can i zip a folder

问题 I'm not sure if this is possible but is there a way to capture screen using an extension without an https url and without going into native code? Does chrome provide some kind of API call for capturing screen with a compression codec that doesn't involve chrome.desktopCapture ? I'm also wondering how something like screencastify works, where does one begin with trying to build something like this? 来源： https://stackoverflow.com/questions/29035215/in-chrome-extensions-is-there-a-way-to-record

问题 I found that, for the same string, the result of using zlib in golang is different with that in c. How can I compress in golang and decompress in c by zlib ? Which version does go use? 回答1: Just because the compressed data is different doesn't mean that it can't be decompressed. zlib-compliant compressed data generated anywhere can be decompressed by a compliant zlib decoder anywhere else. Did you try decompressing? As for the difference, @twotwotwo points out that compress/zlib in Go is not

问题 I have a file that is compressed and I want to decompress it. Do you know if there is a command or do I need to follow another path? 回答1: There isn't one built into FORTRAN 77, but you can shell out to the UNIX commands gzip, gunzip to compress/decompress a file (assuming you are running on UNIX). 回答2: Does this help you? 来源： https://stackoverflow.com/questions/680478/is-there-a-command-in-fortran77-or-later-that-decompresses-a-file

问题 I'm struggling tremendously with this problem. I have a row (B14:CW15) of integers that count how many times each unique string occurs within the original string. It is structured like so. Biagrams: +h hb bl I) )m mj jk km mm mk k^ mm +h Unique Biagrams: +h hb bl I) )m mj jk km mm mk k^ Biagram Count: 2 1 1 1 1 1 1 1 2 1 1 I can't for the life of my figure out how I can extract the top n biagrams from this without excel selecting duplicate biagrams. The Large() function has not worked as it

问题 I am creating a custom message encoder similar to what you have in the WCF example projects(WF_WCF_Samples\WCF\Extensibility\MessageEncoder\Compression). The problem I am having is when sending a request, using the default textMessageEncoder with no compression produces this request after encoding. However, when I am using my custom encoder with gzip compression and sending a request from soapUI this is what I get. As you can see the To and Action are missing. It ends up giving me this

问题 I'm trying to decompress buffer compressed by php deflate implementation. Here's the code: public static void CopyTo(Stream src, Stream dest) { byte[] bytes = new byte[4096]; int cnt, i = 0; while ((cnt = src.Read(bytes, 0, bytes.Length)) != 0 ) { dest.Write(bytes, 0, cnt); } dest.Flush(); } public static byte[] Unzip(byte[] bytes) { using (var msi = new MemoryStream(bytes)) using (var mso = new MemoryStream()) { using (var gs = new DeflateStream(msi, CompressionMode.Decompress)) { msi

问题 This is from a Answer on SO As to the GZIP compression, you shouldn't do it yourself. Let the server do itself. Fix your code to remove all manual attempts to compress the response, it should end up to basically look like this: @Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String json = createItSomehow(); response.setContentType("application/json"); response.setCharacterEncoding("UTF-8"); response.getWriter()
