compression

问题 Is there any way to compress large files into smaller .zip of .tar.gz files in google drive? I tried google appscript but it created .zip files but not compressing. How to do this? 回答1: I have tried and tested the below code with a pdf file which is in my Drive of 10MB size and it did compressed it for 9MB. I even tested for a Drive file(slides), it did compress it. function fileZip(){ var files = DriveApp.getFilesByName('Google_Apps_Script_Second_Edition.pdf'); while (files.hasNext()) { var

问题 Does any mainstream compression algorithm, for example either snappy, zlib or bzip natively support streaming data across the network? For example if I have to send a compressed payload, then will I have to manually prepend the size of the payload before sending the message? Or does any library provide the API to tell whether a message is complete given x bytes? 回答1: zlib, bzip2, lz4, zstd, brotli, lzma2, and many others all support streaming through the use of an end-of-data marker in the

问题 I need to run a script to compress all folders within a folder that is 2 levels within a directory structure. I want the script to compress all folders within the log folder and then delete the original folder, thus saving loads on space. To illustrate the folders I wish to compress, see below: Drive Location-->machinename-->logtype-->folders_i_want_to_compress Within folder 2 there are folders with dates in the format yyyymmdd and it is these that I wish to compress as zip files. I cannot

问题 I want to use gzip or deflate compression on outgoing POST and PUT JSON requests to an API project from an Angular 4 application. Presently, I'm using HttpClient to send the requests. I've tried using pako or zlib to generate the compressed content, but the server returns back responses indicating a bad implementation of the compression algorithm. My POST TypeScript looks like the following: public post(url: string, content: any): Observable < any > { const fullUrl: string = `${HttpService

问题 From this list of examples, it seems that Kakadu is able to compress volumetric images along the z-direction by leveraging the multi-component transform (Part 2) of the JPEG 2000 standard. Specifically example (Aj). I tested it, it seems to work. I tried to modify the example above for an image of 1024 x 1024 x 128 pixels, I want to group slices in batches of 32 (or 64) and do a full DWT on the individual batches, but I fail. This is what I tried: kdu_compress -i img.rawl\*128@2097152 -o img

问题 I am new to System.IO.Compression I am trying to compress and decompress some information. For compression I used code project and it seems to work. I am compressing string at the moment. For decompressing I would like to docompress a Stream This is what I have at the moment var zipString = _compressor.Compress(request); using (var sw = new StreamWriter(req.GetRequestStream())) { sw.Write(zipString); sw.Close(); } WebResponse respStream = req.GetResponse(); Stream resp = respStream
