compression

My TCP Client receives a image within a packet.The image is compressed with zlib.The task is to decompress the image and put it on the form. I'm planning to save the compressed image in the current directory,decompress it and load the decompressed file on the form. The first problem comes with saving the file(compressed).The zlib can save it decompressed. The code below loads the compressed file and saves it after decompression. private void decompressFile(string inFile, string outFile) { System.IO.FileStream outFileStream = new System.IO.FileStream(outFile, System.IO.FileMode.Create); zlib

I'm looking for a tool that allows you to merge 2 large CSS files. All the ones I've tried so far (like CSSMerge) haven't worked out. Some of them just randomly remove properties. Others choke on the non-standard properties like -webkit and -moz and give me errors. And I also need something that preserves the case of each rule. CSSMerge changed all rules to lower-case. Try CSS Compressor & Minifier It have lots of options, you can compress and/or minify css. Copy both CSS files into CSS input Turn on Sort selectors and properties Obtain output Manually remove duplicates Re-enter input compress

I'm trying to encode an image into a byte array and send it to a server. the encoding and sending parts wok fine but my problem is that the byte array is too large and takes too long to send so I thought compressing it would make it go faster. but the actual problem is that I CAN NOT use system.io or streams. and I'm targeting .net 2.0. Thank you. using System.IO; using System.IO.Compression; code: public static byte[] Compress(byte[] data) { MemoryStream output = new MemoryStream(); using (DeflateStream dstream = new DeflateStream(output, CompressionLevel.Optimal)) { dstream.Write(data, 0,

I've been reading this article from Valve that seems to explain the architecture of their multiplayer system. It seems they delay rendering by a couple ticks on the client so they can handle dropped packets, but they also send packets as "delta snapshots" (the difference between two adjacent states). Suppose we have times A, B, C, and the client is correct at time A but drops the packet at B, and then receives the one at C. How can it correctly deduce the state at time C? The packet at C only tells (I think) the delta between states B and C, and the client only knows the state at A. What am I

What I need is to be able to extract the files in a .rar file into streams. I'm creating a test case to get a sense of how to use unrar source . I've been searching and tinkering for a while, but I can't figure out how to use the library. I'm surprised I can't even find documentation or a tutorial for it, considering how common .rar archives are. I've made a bit of progress on my own, but it doesn't always work. Certain files are extracted properly. Other files are jumbled up for some reason (but not completely "garbage" binary data). All I know so far is, usually (but not always): not working

I want to store JSON data in local storage. Sometimes data stored could be more than 5MB(max threshold allowed by browsers for each domain). Is there anyway i can compress or zip the data and store it in local storage ? How much latency it will add if compression and decompression for every JS function on large data ? I am using this json data to display on webpage..... It is like a static data which is mostly same for entire session. we provide actions like search, filter etc on this json data...Whenever user enters a keyword, i search in this json data which is stored in local storage

I understand that GZIP is a combination of LZ77 and Huffman coding and can be configured with a level between 1-9 where 1 indicates the fastest compression (less compression) and 9 indicates the slowest compression method (best compression). My question is, does the choice of level only impact the compression process or is there an additional cost also incurred in decompression depending on the level used to compress? I ask because typically many web servers will GZIP responses on the fly if the client supports it, e.g. Accept-Encoding: gzip . I appreciate that when doing this on the fly a

I have added the following lines in tomcat's conf/server.xml file to enable gzip compression but its not working. Pages are still uncompressesd. <Connector port="8080" compression="on" compressionMinSize="2048" noCompressionUserAgents="gozilla, traviata" compressableMimeType="text/html,text/xml,text/plain,text/css, text/javascript,text/json,application/x-javascript, application/javascript,application/json"/> Any idea? If Tomcat is fronted by Apache on port 80, you will need to enable compression in Apache itself. The compression in Tomcat will only work if you access it directly on port 8080.
